laravel throttle not working code example

Example: throttle laravel

//In Laravel we use throttle middleware to restrict the amount of traffic 
//for a given route or group of routes. The throttle middleware accepts two parameters 
//that determine the maximum number of requests that can be made in a given number of minutes. 
//For example: 
//Here 60 is number of requests you can make in 1 minute.
  
Route::middleware('throttle:60,1')->get('/user', function () { 
  //
});
