jquery - How to write Laravel routing so that it can correctly respond to Ajax requests initiated by the front end in GET mode?

Question

jquery's ajax method, for GET requests, will splice the url and query parameters into http://xxx.xxx/aaa/bbb?arg1=ddd to initiate the request.

I define a route like Route::get('aaa/bbb/{arg1}'). The request that this route can recognize is http://xxx.xxx/aaa/bbb/ddd.

For such a problem, how should laravel's routing be written to correctly respond to the front-end AJAX request?

Post the solved code memo:
Route:
Route::get('getProjectInfoByAPI/{url?}', 'ProjectController@getProjectInfo');
front end:

       $.ajax({
                url: 'getProjectInfoByAPI',
                type: 'GET',
                data: {
                    url: xxx,
                },
                dataType: 'json',
                success: function(response){
    
                }
            });
        });

Answer 1

Route::get('/aaa/bbb/{arg1?}','UserController@arg1');

$.ajax({

         type: 'get',
         url: '/aaa/bbb',
         data: {'arg1': 'ddd'},
         headers: {'X-CSRF-Token': $('meta[name=csrf-token]').attr('content')},
         dataType: 'json',
         success: function (msg) {
            }
        });
