Laravel provides an expressive, minimal API around the Guzzle HTTP client, allowing you to quickly make outgoing HTTP requests to communicate with other web applications. Laravel's wrapper around Guzzle is focused on its most common use cases and a wonderful developer experience.
The HTTP client also allows you to construct request URLs using the URI template specification. To define the URL parameters that can be expanded by your URI template, you may use the withUrlParameters method:

Of course, it is common when making POST, PUT, and PATCH requests to send additional data with your request, so these methods accept an array of data as their second argument. By default, data will be sent using the application/json content type:
If you would like to send files as multi-part requests, you should call the attach method before making your request. This method accepts the name of the file and its contents. If needed, you may provide a third argument which will be considered the file's filename, while a fourth argument may be used to provide headers associated with the file:
If you would like the HTTP client to automatically retry the request if a client or server error occurs, you may use the retry method. The retry method accepts the maximum number of times the request should be attempted and the number of milliseconds that Laravel should wait in between attempts:
If needed, you may pass a third argument to the retry method. The third argument should be a callable that determines if the retries should actually be attempted. For example, you may wish to only retry the request if the initial request encounters an ConnectionException:
If a request attempt fails, you may wish to make a change to the request before a new attempt is made. You can achieve this by modifying the request argument provided to the callable you provided to the retry method. For example, you might want to retry the request with a new authorization token if the first attempt returned an authentication error:
If all of the requests fail, an instance of Illuminate\Http\Client\RequestException will be thrown. If you would like to disable this behavior, you may provide a throw argument with a value of false. When disabled, the last response received by the client will be returned after all retries have been attempted:
Unlike Guzzle's default behavior, Laravel's HTTP client wrapper does not throw exceptions on client or server errors (400 and 500 level responses from servers). You may determine if one of these errors was returned using the successful, clientError, or serverError methods:
If you have a response instance and would like to throw an instance of Illuminate\Http\Client\RequestException if the response status code indicates a client or server error, you may use the throw or throwIf methods:
If you would like to perform some additional logic before the exception is thrown, you may pass a closure to the throw method. The exception will be thrown automatically after the closure is invoked, so you do not need to re-throw the exception from within the closure:
Since Laravel's HTTP client is powered by Guzzle, you may take advantage of Guzzle Middleware to manipulate the outgoing request or inspect the incoming response. To manipulate the outgoing request, register a Guzzle middleware via the withRequestMiddleware method:
Sometimes, you may want to register a middleware that applies to every outgoing request and incoming response. To accomplish this, you may use the globalRequestMiddleware and globalResponseMiddleware methods. Typically, these methods should be invoked in the boot method of your application's AppServiceProvider:
To configure default options for every outgoing request, you may utilize the globalOptions method. Typically, this method should be invoked from the boot method of your application's AppServiceProvider:
Sometimes, you may wish to make multiple HTTP requests concurrently. In other words, you want several requests to be dispatched at the same time instead of issuing the requests sequentially. This can lead to substantial performance improvements when interacting with slow HTTP APIs.
Thankfully, you may accomplish this using the pool method. The pool method accepts a closure which receives an Illuminate\Http\Client\Pool instance, allowing you to easily add requests to the request pool for dispatching:
As you can see, each response instance can be accessed based on the order it was added to the pool. If you wish, you can name the requests using the as method, which allows you to access the corresponding responses by name:
The pool method cannot be chained with other HTTP client methods such as the withHeaders or middleware methods. If you want to apply custom headers or middleware to pooled requests, you should configure those options on each request in the pool:
The Laravel HTTP client allows you to define "macros", which can serve as a fluent, expressive mechanism to configure common request paths and headers when interacting with services throughout your application. To get started, you may define the macro within the boot method of your application's App\Providers\AppServiceProvider class:
Many Laravel services provide functionality to help you easily and expressively write tests, and Laravel's HTTP client is no exception. The Http facade's fake method allows you to instruct the HTTP client to return stubbed / dummy responses when requests are made.
Alternatively, you may pass an array to the fake method. The array's keys should represent URL patterns that you wish to fake and their associated responses. The * character may be used as a wildcard character. Any requests made to URLs that have not been faked will actually be executed. You may use the Http facade's response method to construct stub / fake responses for these endpoints:
When all the responses in a response sequence have been consumed, any further requests will cause the response sequence to throw an exception. If you would like to specify a default response that should be returned when a sequence is empty, you may use the whenEmpty method:
If you require more complicated logic to determine what responses to return for certain endpoints, you may pass a closure to the fake method. This closure will receive an instance of Illuminate\Http\Client\Request and should return a response instance. Within your closure, you may perform whatever logic is necessary to determine what type of response to return:
If you would like to ensure that all requests sent via the HTTP client have been faked throughout your individual test or complete test suite, you can call the preventStrayRequests method. After calling this method, any requests that do not have a corresponding fake response will throw an exception rather than making the actual HTTP request:
When faking responses, you may occasionally wish to inspect the requests the client receives in order to make sure your application is sending the correct data or headers. You may accomplish this by calling the Http::assertSent method after calling Http::fake.
The assertSent method accepts a closure which will receive an Illuminate\Http\Client\Request instance and should return a boolean value indicating if the request matches your expectations. In order for the test to pass, at least one request must have been issued matching the given expectations:
You may use the recorded method to gather all requests and their corresponding responses. The recorded method returns a collection of arrays that contains instances of Illuminate\Http\Client\Request and Illuminate\Http\Client\Response:
Additionally, the recorded method accepts a closure which will receive an instance of Illuminate\Http\Client\Request and Illuminate\Http\Client\Response and may be used to filter request / response pairs based on your expectations:
Laravel fires three events during the process of sending HTTP requests. The RequestSending event is fired prior to a request being sent, while the ResponseReceived event is fired after a response is received for a given request. The ConnectionFailed event is fired if no response is received for a given request.
The RequestSending and ConnectionFailed events both contain a public $request property that you may use to inspect the Illuminate\Http\Client\Request instance. Likewise, the ResponseReceived event contains a $request property as well as a $response property which may be used to inspect the Illuminate\Http\Client\Response instance. You may create event listeners for these events within your application:
All routes and controllers should return a response to be sent back to the user's browser. Laravel provides several different ways to return responses. The most basic response is returning a string from a route or controller. The framework will automatically convert the string into a full HTTP response:
Returning a full Response instance allows you to customize the response's HTTP status code and headers. A Response instance inherits from the Symfony\Component\HttpFoundation\Response class, which provides a variety of methods for building HTTP responses:
You may also return Eloquent ORM models and collections directly from your routes and controllers. When you do, Laravel will automatically convert the models and collections to JSON responses while respecting the model's hidden attributes:
Keep in mind that most response methods are chainable, allowing for the fluent construction of response instances. For example, you may use the header method to add a series of headers to the response before sending it back to the user:
Laravel includes a cache.headers middleware, which may be used to quickly set the Cache-Control header for a group of routes. Directives should be provided using the "snake case" equivalent of the corresponding cache-control directive and should be separated by a semicolon. If etag is specified in the list of directives, an MD5 hash of the response content will automatically be set as the ETag identifier:
You may attach a cookie to an outgoing Illuminate\Http\Response instance using the cookie method. You should pass the name, value, and the number of minutes the cookie should be considered valid to this method: 152ee80cbc
