What are some examples of middleware in Laravel?

In Laravel, middleware acts as a bridge between a request and a response. Here are a few examples:

1. Authenticate: Checks if the user is authenticated.
2. CheckRole: Ensures the user has the right role to access a resource.
3. TrimStrings: Trims whitespace from string inputs.
4. EncryptCookies: Encrypts cookies for security.

Can you explain how to create custom middleware?

Sure! To create custom middleware in Laravel, you can use the artisan command:

php artisan make:middleware CustomMiddleware

This will create a new middleware file in the app/Http/Middleware directory. You can then define your logic in the handle method.

How do I register this middleware?

You can register your middleware in the app/Http/Kernel.php file. Add it to the $routeMiddleware array like this:

protected $routeMiddleware = [
    'custom' => \\App\\Http\\Middleware\\CustomMiddleware::class,
];

Now you can use it in your routes!

What are some common use cases for middleware?

• Authentication and authorization checks
