Extract Token and Role at the backend.md

In Laravel, you can extract the token and other headers from the HTTP request using the request() object, which is an instance of the Illuminate\Http\Request class. Here's how you can extract the token and the role from the request headers:

1. Extracting the Authorization Token:

   To extract the authorization token (usually in Bearer Token format) from the request headers, you can use the header() method on the Request object:

   $token = $request->header('Authorization');

   This will give you the entire authorization header, including the "Bearer " prefix and the token itself. If you want to extract just the token without the "Bearer " prefix, you can further manipulate the string, like so:

   $authorizationHeader = $request->header('Authorization');
   $token = str_replace('Bearer ', '', $authorizationHeader);

2. Extracting the User Role:

   To extract the user role from a custom header (e.g., X-User-Role) in the request headers, you can use the header() method similarly:

   $userRole = $request->header('X-User-Role');

   This code will extract the value of the X-User-Role header from the request headers.

Once you've extracted the token and user role, you can use them in your authentication and authorization logic. For example, you can use Laravel's built-in middleware like auth and create custom middleware to check the token and role before allowing access to specific routes or controller methods.
