发布AJAX调用资源控制器的存储方法不适用于laravel 5.4

我想通过资源控制器使用post类型ajax请求将表单数据存储在数据库中，但它给了我错误 POST http://localhost:8000/reservations 405 (Method Not Allowed)

AJAX

$('#btn_add').click(function() {
      $('#user-form').ajaxSubmit({
          type: 'POST',
          url: '{!! url($route)!!}', //it's http://localhost:8000/reservations
          headers: {
            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
          },
          success: function(result) {
          console.log(result);
              $('#user_up_stat').addClass('modal-' + result['type']);
              $('#user_up_stat_title').html(result['status']);
              $('#user_up_stat_msg').html(result['msg']);
              $('#user_up_stat').modal('show');
          },
          error: function(response){
            console.log(response);
            }
      });
  });

控制器

public function store(Request $request)
 {
    $this->check();
    if($request->name == null || $request->name == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to Update enter a valid name."];
    if($request->email == null || $request->email == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to create select a valid email."];
    if($request->phone == null || $request->phone == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid phone number."];
    if($request->address == null || $request->address == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid address."];
    if($request->checkin_date == null || $request->checkin_date == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid check in date."];
    if($request->checkout_date == null || $request->checkout_date == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid check out date."];
    if($request->room_id == null || $request->room_id == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to Update enter a valid room id."];
    if($request->card_name == null || $request->card_name == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid card name."];
    if($request->card_number == null || $request->card_number == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid card number."];
    if($request->expiry_date == null || $request->expiry_date == '')
        return ['status'=>'Error','type'=>'danger','msg'=>"Unable to update enter a valid expiry date."];
    $reservations=new Reservation();
    $reservations->name = $request->name;
    $reservations->email = $request->email;
    $reservations->address = $request->address;
    $reservations->checkin_date = $request->checkin_date;
    $reservations->checkout_date = $request->checkout_date;
    $reservations->room_id = $request->room_id;
    $reservations->card_name = $request->card_name;
    $reservations->card_number = $request->card_number;
    $reservations->expiry_date = $request->expiry_date;

    if($request->has('card_type'))
        $reservations->card_type = $request->card_type;

    $reservations->save();
    return ['status'=>'Success','type'=>'success','msg'=>'Reservation updated successfully.'];
 }

路线

Route::resource('/reservations' , 'ReservationsController');
