Laravel Intercept throttle exceptions

To intercept and handle throttle exceptions in Laravel, you can create a custom middleware to catch the ThrottleRequestsException. The approach you're trying to use in bootstrap/app.php is not the correct place to handle route-specific exceptions. Instead, you should create a middleware that wraps around the throttle middleware to catch and handle the exception.

Here's how you can achieve this:

1. Create a Custom Middleware:

   First, create a new middleware using the Artisan command:

   php artisan make:middleware HandleThrottleException
   

2. Implement the Middleware Logic:

   Open the newly created middleware file located at app/Http/Middleware/HandleThrottleException.php and modify it to catch the ThrottleRequestsException:

   namespace App\Http\Middleware;
   
   use Closure;
   use Illuminate\Http\Request;
   use Illuminate\Routing\Middleware\ThrottleRequests;
   use Illuminate\Http\Exceptions\ThrottleRequestsException;
   use Illuminate\Support\Facades\Log;
   
   class HandleThrottleException extends ThrottleRequests
   {
       public function handle(Request $request, Closure $next, $maxAttempts = 60, $decayMinutes = 1, $prefix = '')
       {
           try {
               return parent::handle($request, $next, $maxAttempts, $decayMinutes, $prefix);
           } catch (ThrottleRequestsException $e) {
               // Log the exception or perform any other action
               Log::channel('login_errors')->error("{$request->ip()} Excessive throttling attempts");
   
               // Return a custom response
               return response()->json([
                   'message' => 'Too many login attempts. Banned for 1 hour',
               ], 429);
           }
       }
   }
   

3. Register the Middleware:

   Register your custom middleware in app/Http/Kernel.php. You can add it to the $routeMiddleware array:

   protected $routeMiddleware = [
       // Other middleware
       'handleThrottle' => \App\Http\Middleware\HandleThrottleException::class,
   ];
   

4. Apply the Middleware to Your Route:

   Finally, apply your custom middleware to the route:

   Route::middleware('handleThrottle:4,1')->get('/', function () {
       if (auth()->check()) {
           return redirect()->route('dashboard');
       }
   
       return view('home');
   })->name('login');
   

By following these steps, you can effectively intercept and handle throttle exceptions in your Laravel application.
