In Laravel, both request classes and policies can handle authorization.
Request classes have an authorize method that is called automatically by the framework before the request is handled. It is a convenient way to perform authorization checks on a specific request.
Policies provide a more flexible and reusable way to handle authorization across multiple request classes. They are classes that organize authorization logic around a particular model or resource. They allow you to define granular abilities for your application's users and groups.
When both the request's authorize method and a policy's __call method (or method with the same name as the action) return false for the same action, the framework will consider the user as unauthorized and will return a 403 Forbidden response.
In such scenarios, the priority is given to the authorize method of the request class. If it returns true, the framework will continue to process the request and will not check against any policy. However, if it returns false or throws an exception, Laravel will check the policy's method with the same name as the action, and if it returns false, the user will be considered unauthorized and a 403 Forbidden response will be returned.
In summary, both request classes and policies can handle authorization in Laravel, with priority given to the authorize method of request classes.
