Laravel 10 Get Request Header Example

Hello, developers, In this article, we'll see how to get a request header in laravel 10. Here, we'll see the header value in laravel 10. In this tutorial, we'll create an endpoint to retrieve all headers or specific ones effortlessly.

Here, we'll use the header() request method and get the header request value.

Laravel 10 Get Request Header

Define a route in your routes/web.php file or routes/api.php file, depending on whether you are working with a web or API route.

use App\Http\Controllers\UserController;

Route::get('/get-request-headers', [UserController::class, 'getRequestHeaders']);

Now, we'll create a controller using the following command.

php artisan make:controller UserController

Next, open the controller and implement the method to retrieve request headers:

app/Http/Controller/UserController

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class UserController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function getRequestHeaders(Request $request)
    {
        $headers = $request->header(); /* Getting All Headers from request */
  
        $header = $request->header('Accept'); /* Getting Singe Header value from request */
    
        return response()->json($headers);
    }
}

Now, run the laravel 10 application using the following command.

php artisan serve

If you want to retrieve a specific header, you can use the header method on the request:

public function getRequestHeaders(Request $request)
{
    // Retrieve a specific header
    $contentType = $request->header('Content-Type');

    return response()->json(['Content-Type' => $contentType]);
}

To handle cases where a header may not exist, you can use the has method:

public function getRequestHeaders(Request $request)
{
    // Check if a header exists
    if ($request->headers->has('Authorization')) {
        $authorizationHeader = $request->header('Authorization');
        return response()->json(['Authorization' => $authorizationHeader]);
    } else {
        return response()->json(['message' => 'Authorization header not present'], 400);
    }
}
