• Accessing The Request
  • Request Path & Method
  • PSR-7 Requests
• Retrieving Input
  • Old Input
  • Cookies
• Files

  • Storing Uploaded Files

Accessing The Request

To obtain an instance of the current HTTP request via dependency injection, you should type-hint the Illuminate\Http\Request class on your controller method. The incoming request instance will automatically be injected by the service container:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    /**
     * Store a new user.
     *
     * @param  Request  $request
     * @return Response
     */
    public function store(Request $request)
    {
        $name = $request->input('name');

        //
    }
}

Dependency Injection & Route Parameters

If your controller method is also expecting input from a route parameter you should list your route parameters after your other dependencies. For example, if your route is defined like so:

Route::put('user/{id}', 'UserController@update');

You may still type-hint the Illuminate\Http\Request and access your route parameter id by defining your controller method as follows:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    /**
     * Update the specified user.
     *
     * @param  Request  $request
     * @param  string  $id
     * @return Response
     */
    public function update(Request $request, $id)
    {
        //
    }
}

Accessing The Request Via Route Closures

You may also type-hint the Illuminate\Http\Request class on a route Closure. The service container will automatically inject the incoming request into the Closure when it is executed:

use Illuminate\Http\Request;

Route::get('/', function (Request $request) {
    //
});
