/** * The trusted proxies for this application * * @var array */ protected $proxies = [ '192.168.1.1', '192.168.1.2', ]; /** * The headers that should be used to detect proxies * * @var string */ protected $headers = Request::HEADER_X_FORWARDED_ALL;

As you can see, the $headers array defaults to trusting all forwarded headers from the trusted proxies; if you want to customize this list, take a look at the Symfony docs on trusting proxies.

Testing

Outside of the context of you as a developer using requests, responses, and middleware in your own testing, Laravel itself actually uses each quite a bit.

When you’re doing application testing with calls like $this->get('/'), you’re instructing Laravel’s application testing framework to generate request objects that represent the interactions that you’re describing. Then those request objects are passed to your application as these were actual visits. That’s why the application tests are so accurate: your application doesn’t actually “know” that it’s not a real user that’s interacting with it.

In this context, many of the assertions you’re making—say, assertResponseOk()—are assertions against the response object generated by the application testing framework. The assertResponseOk() method just looks at the response object and asserts that its isOk() method returns true—which is just checking that its status code is 200. In the end, everything in application testing is acting as if this were a real page request.

Find yourself in a context where you need a request to work with in your tests? You can always pull one from the container with $request = request(). Or you could create your own—the constructor parameters for the Request class, all optional, are as follows:
