How to set request headers in laravel

Laravel is a popular PHP framework that provides rich features and good design patterns to help us build efficient and maintainable web applications. In actual development, sometimes we need to set some customized information in the request headers of Laravel applications. This article will introduce how to set request headers in Laravel.

1. Use middleware to set request headers

In Laravel, we can use middleware middleware to set request headers. In a Laravel application, middleware is a special component used to handle HTTP requests and responses. Therefore, using middleware to set request headers is an excellent choice.

We can use Laravel's make:middleware command to create a middleware:

php artisan make:middleware SetCustomHeader

In the newly created SetCustomHeader class, we can add the request header information we need in the handle method:

namespace App\Http\Middleware;

use Closure;

class SetCustomHeader
{
    public function handle($request, Closure $next)
    {
        $request->headers->set('Custom-Header', 'Custom Value');

        return $next($request);
    }
}

In the above code, we use the $request->headers->set() method to set the request header information. Custom-Header here is the name of the custom header information, and Custom Value is the custom value we set.

After setting up the middleware, we also need to register it in the global middleware of the application. In the app/Http/Kernel.php file, add our new middleware to the middleware array $middlewareGroups:

protected $middlewareGroups = [
    'web' => [
        // other middleware
        \App\Http\Middleware\SetCustomHeader::class,
    ],

    // other middleware groups
];

Then we can start using the new custom request header.

2. Use global middleware to set request headers

In Laravel, we can also use global middleware to set request headers. Global middleware will be executed during each request processing. Therefore, global middleware can also easily set request header information.

First, we need to register a new middleware in the global middleware of the application:

protected $middleware = [
    // other middleware
    \App\Http\Middleware\SetCustomHeader::class,
];

Then, we can set custom request headers in the middleware class as in the previous section Message:

namespace App\Http\Middleware;

use Closure;

class SetCustomHeader
{
    public function handle($request, Closure $next)
    {
        $request->headers->set('Custom-Header', 'Custom Value');

        return $next($request);
    }
}

Finally, we can use Laravel's request and response functionality as usual, and they will include the custom request headers we just set.

Summary

In this article, we introduced how to set custom request header information in Laravel. We can use middleware or global middleware to achieve this function. Either way, setting request header information is very simple. By setting custom request header information, we can add more functions and features to the application.
