Any -HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be -updated to work with the new immutable PSR-7 request and response objects. Any -event listeners or subscribers need to be updated to become middleware -functions that wrap handlers (or are injected into a -`GuzzleHttp\HandlerStack`). - -- Removed `GuzzleHttp\BatchResults` -- Removed `GuzzleHttp\Collection` -- Removed `GuzzleHttp\HasDataTrait` -- Removed `GuzzleHttp\ToArrayInterface` -- The `guzzlehttp/streams` dependency has been removed. Stream functionality - is now present in the `GuzzleHttp\Psr7` namespace provided by the - `guzzlehttp/psr7` package. -- Guzzle no longer uses ReactPHP promises and now uses the - `guzzlehttp/promises` library. We use a custom promise library for three - significant reasons: - 1. React promises (at the time of writing this) are recursive. Promise - chaining and promise resolution will eventually blow the stack. Guzzle - promises are not recursive as they use a sort of trampolining technique. - Note: there has been movement in the React project to modify promises to - no longer utilize recursion. - 2. Guzzle needs to have the ability to synchronously block on a promise to - wait for a result. Guzzle promises allows this functionality (and does - not require the use of recursion). - 3. Because we need to be able to wait on a result, doing so using React - promises requires wrapping react promises with RingPHP futures. This - overhead is no longer needed, reducing stack sizes, reducing complexity, - and improving performance. -- `GuzzleHttp\Mimetypes` has been moved to a function in - `GuzzleHttp\Psr7\mimetype_from_extension` and - `GuzzleHttp\Psr7\mimetype_from_filename`. -- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query - strings must now be passed into request objects as strings, or provided to - the `query` request option when creating requests with clients. The `query` - option uses PHP's `http_build_query` to convert an array to a string. If you - need a different serialization technique, you will need to pass the query - string in as a string. There are a couple helper functions that will make - working with query strings easier: `GuzzleHttp\Psr7\parse_query` and - `GuzzleHttp\Psr7\build_query`. -- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware - system based on PSR-7, using RingPHP and it's middleware system as well adds - more complexity than the benefits it provides. All HTTP handlers that were - present in RingPHP have been modified to work directly with PSR-7 messages - and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces - complexity in Guzzle, removes a dependency, and improves performance. RingPHP - will be maintained for Guzzle 5 support, but will no longer be a part of - Guzzle 6. -- As Guzzle now uses a middleware based systems the event system and RingPHP - integration has been removed. Note: while the event system has been removed, - it is possible to add your own type of event system that is powered by the - middleware system. - - Removed the `Event` namespace. - - Removed the `Subscriber` namespace. - - Removed `Transaction` class - - Removed `RequestFsm` - - Removed `RingBridge` - - `GuzzleHttp\Subscriber\Cookie` is now provided by - `GuzzleHttp\Middleware::cookies` - - `GuzzleHttp\Subscriber\HttpError` is now provided by - `GuzzleHttp\Middleware::httpError` - - `GuzzleHttp\Subscriber\History` is now provided by - `GuzzleHttp\Middleware::history` - - `GuzzleHttp\Subscriber\Mock` is now provided by - `GuzzleHttp\Handler\MockHandler` - - `GuzzleHttp\Subscriber\Prepare` is now provided by - `GuzzleHttp\PrepareBodyMiddleware` - - `GuzzleHttp\Subscriber\Redirect` is now provided by - `GuzzleHttp\RedirectMiddleware` -- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in - `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone. -- Static functions in `GuzzleHttp\Utils` have been moved to namespaced - functions under the `GuzzleHttp` namespace. This requires either a Composer - based autoloader or you to include functions.php. -- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to - `GuzzleHttp\ClientInterface::getConfig`. -- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed. -- The `json` and `xml` methods of response objects has been removed. With the - migration to strictly adhering to PSR-7 as the interface for Guzzle messages, - adding methods to message interfaces would actually require Guzzle messages - to extend from PSR-7 messages rather then work with them directly. - -## Migrating to middleware - -The change to PSR-7 unfortunately required significant refactoring to Guzzle -due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event -system from plugins. The event system relied on mutability of HTTP messages and -side effects in order to work. With immutable messages, you have to change your -workflow to become more about either returning a value (e.g., functional -middlewares) or setting a value on an object. Guzzle v6 has chosen the -functional middleware approach. - -Instead of using the event system to listen for things like the `before` event, -you now create a stack based middleware function that intercepts a request on -the way in and the promise of the response on the way out. This is a much -simpler and more predictable approach than the event system and works nicely -with PSR-7 middleware. Due to the use of promises, the middleware system is -also asynchronous. - -v5: - -```php -use GuzzleHttp\Event\BeforeEvent; -$client = new GuzzleHttp\Client(); -// Get the emitter and listen to the before event. -$client->getEmitter()->on('before', function (BeforeEvent $e) { - // Guzzle v5 events relied on mutation - $e->getRequest()->setHeader('X-Foo', 'Bar'); -}); -``` - -v6: - -In v6, you can modify the request before it is sent using the `mapRequest` -middleware. The idiomatic way in v6 to modify the request/response lifecycle is -to setup a handler middleware stack up front and inject the handler into a -client. - -```php -use GuzzleHttp\Middleware; -// Create a handler stack that has all of the default middlewares attached -$handler = GuzzleHttp\HandlerStack::create(); -// Push the handler onto the handler stack -$handler->push(Middleware::mapRequest(function (RequestInterface $request) { - // Notice that we have to return a request object - return $request->withHeader('X-Foo', 'Bar'); -})); -// Inject the handler into the client -$client = new GuzzleHttp\Client(['handler' => $handler]); -``` - -## POST Requests - -This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params) -and `multipart` request options. `form_params` is an associative array of -strings or array of strings and is used to serialize an -`application/x-www-form-urlencoded` POST request. The -[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart) -option is now used to send a multipart/form-data POST request. - -`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add -POST files to a multipart/form-data request. - -The `body` option no longer accepts an array to send POST requests. Please use -`multipart` or `form_params` instead. - -The `base_url` option has been renamed to `base_uri`. - -4.x to 5.0 ----------- - -## Rewritten Adapter Layer - -Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send -HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor -is still supported, but it has now been renamed to `handler`. Instead of -passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP -`callable` that follows the RingPHP specification. - -## Removed Fluent Interfaces - -[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil) -from the following classes: - -- `GuzzleHttp\Collection` -- `GuzzleHttp\Url` -- `GuzzleHttp\Query` -- `GuzzleHttp\Post\PostBody` -- `GuzzleHttp\Cookie\SetCookie` - -## Removed functions.php - -Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following -functions can be used as replacements. - -- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode` -- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath` -- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path` -- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however, - deprecated in favor of using `GuzzleHttp\Pool::batch()`. - -The "procedural" global client has been removed with no replacement (e.g., -`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client` -object as a replacement. - -## `throwImmediately` has been removed - -The concept of "throwImmediately" has been removed from exceptions and error -events. This control mechanism was used to stop a transfer of concurrent -requests from completing. This can now be handled by throwing the exception or -by cancelling a pool of requests or each outstanding future request -individually. - -## headers event has been removed - -Removed the "headers" event. This event was only useful for changing the -body a response once the headers of the response were known. You can implement -a similar behavior in a number of ways. One example might be to use a -FnStream that has access to the transaction being sent. For example, when the -first byte is written, you could check if the response headers match your -expectations, and if so, change the actual stream body that is being -written to. - -## Updates to HTTP Messages - -Removed the `asArray` parameter from -`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header -value as an array, then use the newly added `getHeaderAsArray()` method of -`MessageInterface`. This change makes the Guzzle interfaces compatible with -the PSR-7 interfaces. - -3.x to 4.0 ----------- - -## Overarching changes: - -- Now requires PHP 5.4 or greater. -- No longer requires cURL to send requests. -- Guzzle no longer wraps every exception it throws. Only exceptions that are - recoverable are now wrapped by Guzzle. -- Various namespaces have been removed or renamed. -- No longer requiring the Symfony EventDispatcher. A custom event dispatcher - based on the Symfony EventDispatcher is - now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant - speed and functionality improvements). - -Changes per Guzzle 3.x namespace are described below. - -## Batch - -The `Guzzle\Batch` namespace has been removed. This is best left to -third-parties to implement on top of Guzzle's core HTTP library. - -## Cache - -The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement -has been implemented yet, but hoping to utilize a PSR cache interface). - -## Common - -- Removed all of the wrapped exceptions. It's better to use the standard PHP - library for unrecoverable exceptions. -- `FromConfigInterface` has been removed. -- `Guzzle\Common\Version` has been removed. The VERSION constant can be found - at `GuzzleHttp\ClientInterface::VERSION`. - -### Collection - -- `getAll` has been removed. Use `toArray` to convert a collection to an array. -- `inject` has been removed. -- `keySearch` has been removed. -- `getPath` no longer supports wildcard expressions. Use something better like - JMESPath for this. -- `setPath` now supports appending to an existing array via the `[]` notation. - -### Events - -Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses -`GuzzleHttp\Event\Emitter`. - -- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by - `GuzzleHttp\Event\EmitterInterface`. -- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by - `GuzzleHttp\Event\Emitter`. -- `Symfony\Component\EventDispatcher\Event` is replaced by - `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in - `GuzzleHttp\Event\EventInterface`. -- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and - `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the - event emitter of a request, client, etc. now uses the `getEmitter` method - rather than the `getDispatcher` method. - -#### Emitter - -- Use the `once()` method to add a listener that automatically removes itself - the first time it is invoked. -- Use the `listeners()` method to retrieve a list of event listeners rather than - the `getListeners()` method. -- Use `emit()` instead of `dispatch()` to emit an event from an emitter. -- Use `attach()` instead of `addSubscriber()` and `detach()` instead of - `removeSubscriber()`. - -```php -$mock = new Mock(); -// 3.x -$request->getEventDispatcher()->addSubscriber($mock); -$request->getEventDispatcher()->removeSubscriber($mock); -// 4.x -$request->getEmitter()->attach($mock); -$request->getEmitter()->detach($mock); -``` - -Use the `on()` method to add a listener rather than the `addListener()` method. - -```php -// 3.x -$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } ); -// 4.x -$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } ); -``` - -## Http - -### General changes - -- The cacert.pem certificate has been moved to `src/cacert.pem`. -- Added the concept of adapters that are used to transfer requests over the - wire. -- Simplified the event system. -- Sending requests in parallel is still possible, but batching is no longer a - concept of the HTTP layer. Instead, you must use the `complete` and `error` - events to asynchronously manage parallel request transfers. -- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`. -- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`. -- QueryAggregators have been rewritten so that they are simply callable - functions. -- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in - `functions.php` for an easy to use static client instance. -- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from - `GuzzleHttp\Exception\TransferException`. - -### Client - -Calling methods like `get()`, `post()`, `head()`, etc. no longer create and -return a request, but rather creates a request, sends the request, and returns -the response. - -```php -// 3.0 -$request = $client->get('/'); -$response = $request->send(); - -// 4.0 -$response = $client->get('/'); - -// or, to mirror the previous behavior -$request = $client->createRequest('GET', '/'); -$response = $client->send($request); -``` - -`GuzzleHttp\ClientInterface` has changed. - -- The `send` method no longer accepts more than one request. Use `sendAll` to - send multiple requests in parallel. -- `setUserAgent()` has been removed. Use a default request option instead. You - could, for example, do something like: - `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`. -- `setSslVerification()` has been removed. Use default request options instead, - like `$client->setConfig('defaults/verify', true)`. - -`GuzzleHttp\Client` has changed. - -- The constructor now accepts only an associative array. You can include a - `base_url` string or array to use a URI template as the base URL of a client. - You can also specify a `defaults` key that is an associative array of default - request options. You can pass an `adapter` to use a custom adapter, - `batch_adapter` to use a custom adapter for sending requests in parallel, or - a `message_factory` to change the factory used to create HTTP requests and - responses. -- The client no longer emits a `client.create_request` event. -- Creating requests with a client no longer automatically utilize a URI - template. You must pass an array into a creational method (e.g., - `createRequest`, `get`, `put`, etc.) in order to expand a URI template. - -### Messages - -Messages no longer have references to their counterparts (i.e., a request no -longer has a reference to it's response, and a response no loger has a -reference to its request). This association is now managed through a -`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to -these transaction objects using request events that are emitted over the -lifecycle of a request. - -#### Requests with a body - -- `GuzzleHttp\Message\EntityEnclosingRequest` and - `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The - separation between requests that contain a body and requests that do not - contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface` - handles both use cases. -- Any method that previously accepts a `GuzzleHttp\Response` object now accept a - `GuzzleHttp\Message\ResponseInterface`. -- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to - `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create - both requests and responses and is implemented in - `GuzzleHttp\Message\MessageFactory`. -- POST field and file methods have been removed from the request object. You - must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface` - to control the format of a POST body. Requests that are created using a - standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use - a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if - the method is POST and no body is provided. - -```php -$request = $client->createRequest('POST', '/'); -$request->getBody()->setField('foo', 'bar'); -$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r'))); -``` - -#### Headers - -- `GuzzleHttp\Message\Header` has been removed. Header values are now simply - represented by an array of values or as a string. Header values are returned - as a string by default when retrieving a header value from a message. You can - pass an optional argument of `true` to retrieve a header value as an array - of strings instead of a single concatenated string. -- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to - `GuzzleHttp\Post`. This interface has been simplified and now allows the - addition of arbitrary headers. -- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most - of the custom headers are now handled separately in specific - subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has - been updated to properly handle headers that contain parameters (like the - `Link` header). - -#### Responses - -- `GuzzleHttp\Message\Response::getInfo()` and - `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event - system to retrieve this type of information. -- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed. -- `GuzzleHttp\Message\Response::getMessage()` has been removed. -- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific - methods have moved to the CacheSubscriber. -- Header specific helper functions like `getContentMd5()` have been removed. - Just use `getHeader('Content-MD5')` instead. -- `GuzzleHttp\Message\Response::setRequest()` and - `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event - system to work with request and response objects as a transaction. -- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the - Redirect subscriber instead. -- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have - been removed. Use `getStatusCode()` instead. - -#### Streaming responses - -Streaming requests can now be created by a client directly, returning a -`GuzzleHttp\Message\ResponseInterface` object that contains a body stream -referencing an open PHP HTTP stream. - -```php -// 3.0 -use Guzzle\Stream\PhpStreamRequestFactory; -$request = $client->get('/'); -$factory = new PhpStreamRequestFactory(); -$stream = $factory->fromRequest($request); -$data = $stream->read(1024); - -// 4.0 -$response = $client->get('/', ['stream' => true]); -// Read some data off of the stream in the response body -$data = $response->getBody()->read(1024); -``` - -#### Redirects - -The `configureRedirects()` method has been removed in favor of a -`allow_redirects` request option. - -```php -// Standard redirects with a default of a max of 5 redirects -$request = $client->createRequest('GET', '/', ['allow_redirects' => true]); - -// Strict redirects with a custom number of redirects -$request = $client->createRequest('GET', '/', [ - 'allow_redirects' => ['max' => 5, 'strict' => true] -]); -``` - -#### EntityBody - -EntityBody interfaces and classes have been removed or moved to -`GuzzleHttp\Stream`. All classes and interfaces that once required -`GuzzleHttp\EntityBodyInterface` now require -`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no -longer uses `GuzzleHttp\EntityBody::factory` but now uses -`GuzzleHttp\Stream\Stream::factory` or even better: -`GuzzleHttp\Stream\create()`. - -- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface` -- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream` -- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream` -- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream` -- `Guzzle\Http\IoEmittyinEntityBody` has been removed. - -#### Request lifecycle events - -Requests previously submitted a large number of requests. The number of events -emitted over the lifecycle of a request has been significantly reduced to make -it easier to understand how to extend the behavior of a request. All events -emitted during the lifecycle of a request now emit a custom -`GuzzleHttp\Event\EventInterface` object that contains context providing -methods and a way in which to modify the transaction at that specific point in -time (e.g., intercept the request and set a response on the transaction). - -- `request.before_send` has been renamed to `before` and now emits a - `GuzzleHttp\Event\BeforeEvent` -- `request.complete` has been renamed to `complete` and now emits a - `GuzzleHttp\Event\CompleteEvent`. -- `request.sent` has been removed. Use `complete`. -- `request.success` has been removed. Use `complete`. -- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`. -- `request.exception` has been removed. Use `error`. -- `request.receive.status_line` has been removed. -- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to - maintain a status update. -- `curl.callback.write` has been removed. Use a custom `StreamInterface` to - intercept writes. -- `curl.callback.read` has been removed. Use a custom `StreamInterface` to - intercept reads. - -`headers` is a new event that is emitted after the response headers of a -request have been received before the body of the response is downloaded. This -event emits a `GuzzleHttp\Event\HeadersEvent`. - -You can intercept a request and inject a response using the `intercept()` event -of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and -`GuzzleHttp\Event\ErrorEvent` event. - -See: http://docs.guzzlephp.org/en/latest/events.html - -## Inflection - -The `Guzzle\Inflection` namespace has been removed. This is not a core concern -of Guzzle. - -## Iterator - -The `Guzzle\Iterator` namespace has been removed. - -- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and - `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of - Guzzle itself. -- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent - class is shipped with PHP 5.4. -- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because - it's easier to just wrap an iterator in a generator that maps values. - -For a replacement of these iterators, see https://github.com/nikic/iter - -## Log - -The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The -`Guzzle\Log` namespace has been removed. Guzzle now relies on -`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been -moved to `GuzzleHttp\Subscriber\Log\Formatter`. - -## Parser - -The `Guzzle\Parser` namespace has been removed. This was previously used to -make it possible to plug in custom parsers for cookies, messages, URI -templates, and URLs; however, this level of complexity is not needed in Guzzle -so it has been removed. - -- Cookie: Cookie parsing logic has been moved to - `GuzzleHttp\Cookie\SetCookie::fromString`. -- Message: Message parsing logic for both requests and responses has been moved - to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only - used in debugging or deserializing messages, so it doesn't make sense for - Guzzle as a library to add this level of complexity to parsing messages. -- UriTemplate: URI template parsing has been moved to - `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL - URI template library if it is installed. -- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously - it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary, - then developers are free to subclass `GuzzleHttp\Url`. - -## Plugin - -The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`. -Several plugins are shipping with the core Guzzle library under this namespace. - -- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar - code has moved to `GuzzleHttp\Cookie`. -- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin. -- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is - received. -- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin. -- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before - sending. This subscriber is attached to all requests by default. -- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin. - -The following plugins have been removed (third-parties are free to re-implement -these if needed): - -- `GuzzleHttp\Plugin\Async` has been removed. -- `GuzzleHttp\Plugin\CurlAuth` has been removed. -- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This - functionality should instead be implemented with event listeners that occur - after normal response parsing occurs in the guzzle/command package. - -The following plugins are not part of the core Guzzle package, but are provided -in separate repositories: - -- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler - to build custom retry policies using simple functions rather than various - chained classes. See: https://github.com/guzzle/retry-subscriber -- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to - https://github.com/guzzle/cache-subscriber -- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to - https://github.com/guzzle/log-subscriber -- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to - https://github.com/guzzle/message-integrity-subscriber -- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to - `GuzzleHttp\Subscriber\MockSubscriber`. -- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to - https://github.com/guzzle/oauth-subscriber - -## Service - -The service description layer of Guzzle has moved into two separate packages: - -- http://github.com/guzzle/command Provides a high level abstraction over web - services by representing web service operations using commands. -- http://github.com/guzzle/guzzle-services Provides an implementation of - guzzle/command that provides request serialization and response parsing using - Guzzle service descriptions. - -## Stream - -Stream have moved to a separate package available at -https://github.com/guzzle/streams. - -`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take -on the responsibilities of `Guzzle\Http\EntityBody` and -`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number -of methods implemented by the `StreamInterface` has been drastically reduced to -allow developers to more easily extend and decorate stream behavior. - -## Removed methods from StreamInterface - -- `getStream` and `setStream` have been removed to better encapsulate streams. -- `getMetadata` and `setMetadata` have been removed in favor of - `GuzzleHttp\Stream\MetadataStreamInterface`. -- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been - removed. This data is accessible when - using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`. -- `rewind` has been removed. Use `seek(0)` for a similar behavior. - -## Renamed methods - -- `detachStream` has been renamed to `detach`. -- `feof` has been renamed to `eof`. -- `ftell` has been renamed to `tell`. -- `readLine` has moved from an instance method to a static class method of - `GuzzleHttp\Stream\Stream`. - -## Metadata streams - -`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams -that contain additional metadata accessible via `getMetadata()`. -`GuzzleHttp\Stream\StreamInterface::getMetadata` and -`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed. - -## StreamRequestFactory - -The entire concept of the StreamRequestFactory has been removed. The way this -was used in Guzzle 3 broke the actual interface of sending streaming requests -(instead of getting back a Response, you got a StreamInterface). Streaming -PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`. - -3.6 to 3.7 ----------- - -### Deprecations - -- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.: - -```php -\Guzzle\Common\Version::$emitWarnings = true; -``` - -The following APIs and options have been marked as deprecated: - -- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead. -- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead. -- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead. -- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead. -- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead. -- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated -- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client. -- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8. -- Marked `Guzzle\Common\Collection::inject()` as deprecated. -- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use - `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or - `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` - -3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational -request methods. When paired with a client's configuration settings, these options allow you to specify default settings -for various aspects of a request. Because these options make other previous configuration options redundant, several -configuration options and methods of a client and AbstractCommand have been deprecated. - -- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`. -- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`. -- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')` -- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0 - - $command = $client->getCommand('foo', array( - 'command.headers' => array('Test' => '123'), - 'command.response_body' => '/path/to/file' - )); - - // Should be changed to: - - $command = $client->getCommand('foo', array( - 'command.request_options' => array( - 'headers' => array('Test' => '123'), - 'save_as' => '/path/to/file' - ) - )); - -### Interface changes - -Additions and changes (you will need to update any implementations or subclasses you may have created): - -- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`: - createRequest, head, delete, put, patch, post, options, prepareRequest -- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()` -- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface` -- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to - `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a - resource, string, or EntityBody into the $options parameter to specify the download location of the response. -- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a - default `array()` -- Added `Guzzle\Stream\StreamInterface::isRepeatable` -- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods. - -The following methods were removed from interfaces. All of these methods are still available in the concrete classes -that implement them, but you should update your code to use alternative methods: - -- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use - `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or - `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or - `$client->setDefaultOption('headers/{header_name}', 'value')`. or - `$client->setDefaultOption('headers', array('header_name' => 'value'))`. -- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`. -- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail. -- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail. -- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail. -- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin. -- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin. -- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin. - -### Cache plugin breaking changes - -- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a - CacheStorageInterface. These two objects and interface will be removed in a future version. -- Always setting X-cache headers on cached responses -- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin -- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface - $request, Response $response);` -- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);` -- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);` -- Added `CacheStorageInterface::purge($url)` -- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin - $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache, - CanCacheStrategyInterface $canCache = null)` -- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)` - -3.5 to 3.6 ----------- - -* Mixed casing of headers are now forced to be a single consistent casing across all values for that header. -* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution -* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader(). - For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader(). - Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request. -* Specific header implementations can be created for complex headers. When a message creates a header, it uses a - HeaderFactory which can map specific headers to specific header classes. There is now a Link header and - CacheControl header implementation. -* Moved getLinks() from Response to just be used on a Link header object. - -If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the -HeaderInterface (e.g. toArray(), getAll(), etc.). - -### Interface changes - -* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate -* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti() -* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in - Guzzle\Http\Curl\RequestMediator -* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string. -* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface -* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders() - -### Removed deprecated functions - -* Removed Guzzle\Parser\ParserRegister::get(). Use getParser() -* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser(). - -### Deprecations - -* The ability to case-insensitively search for header values -* Guzzle\Http\Message\Header::hasExactHeader -* Guzzle\Http\Message\Header::raw. Use getAll() -* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object - instead. - -### Other changes - -* All response header helper functions return a string rather than mixing Header objects and strings inconsistently -* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle - directly via interfaces -* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist - but are a no-op until removed. -* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a - `Guzzle\Service\Command\ArrayCommandInterface`. -* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response - on a request while the request is still being transferred -* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess - -3.3 to 3.4 ----------- - -Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs. - -3.2 to 3.3 ----------- - -### Response::getEtag() quote stripping removed - -`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header - -### Removed `Guzzle\Http\Utils` - -The `Guzzle\Http\Utils` class was removed. This class was only used for testing. - -### Stream wrapper and type - -`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase. - -### curl.emit_io became emit_io - -Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the -'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io' - -3.1 to 3.2 ----------- - -### CurlMulti is no longer reused globally - -Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added -to a single client can pollute requests dispatched from other clients. - -If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the -ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is -created. - -```php -$multi = new Guzzle\Http\Curl\CurlMulti(); -$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json'); -$builder->addListener('service_builder.create_client', function ($event) use ($multi) { - $event['client']->setCurlMulti($multi); -} -}); -``` - -### No default path - -URLs no longer have a default path value of '/' if no path was specified. - -Before: - -```php -$request = $client->get('http://www.foo.com'); -echo $request->getUrl(); -// >> http://www.foo.com/ -``` - -After: - -```php -$request = $client->get('http://www.foo.com'); -echo $request->getUrl(); -// >> http://www.foo.com -``` - -### Less verbose BadResponseException - -The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and -response information. You can, however, get access to the request and response object by calling `getRequest()` or -`getResponse()` on the exception object. - -### Query parameter aggregation - -Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a -setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is -responsible for handling the aggregation of multi-valued query string variables into a flattened hash. - -2.8 to 3.x ----------- - -### Guzzle\Service\Inspector - -Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig` - -**Before** - -```php -use Guzzle\Service\Inspector; - -class YourClient extends \Guzzle\Service\Client -{ - public static function factory($config = array()) - { - $default = array(); - $required = array('base_url', 'username', 'api_key'); - $config = Inspector::fromConfig($config, $default, $required); - - $client = new self( - $config->get('base_url'), - $config->get('username'), - $config->get('api_key') - ); - $client->setConfig($config); - - $client->setDescription(ServiceDescription::factory(__DIR__ .
