Вызов AJAX в Laravel возвращает исключение Http

Question

Когда я пытался использовать ajax в laravel, он показывает следующую ошибку:

Код моего контроллера:

public function getPublicAttraction(Request $request)
    {
        return response(['msg'=>'success']);
    }

Вызов ajax,

<script>
    function getAttraction()
    {

        var pass= {'_token':$('meta[name="csrf-token"]').attr('content')

    };
    $.ajax({
            type:'POST',
            url:'{{route("Attractions")}}',
            datatype:'json',
            data: pass,
            success:function(data){
                $("#public_attractions").html(data.msg);
            }
        }).fail(function(jqXHR, textStatus, error){
            $("#public_attractions").html(jqXHR.responseText);
        });


    }
    $(document).ready(function(){
         getAttraction();
    });
</script>

метатег с токеном csrf,

<meta name="csrf-token" content="!!{csrf_token()}!!">

запись файла маршрута web.php,

Route::post('/getAttractions','AjaxController@getPublicAttraction')->name('Attractions');

Я думаю, что застрял, пожалуйста, помогите.

Answer 1

Хорошо, все выглядит хорошо, за исключением того, что метатег CSRF, потому что вам не нужно ничего экранировать в токене csrf, поэтому правильный способ печати токена будет: <!-- CSRF Token --> <meta name="csrf-token" content="{{ csrf_token() }}"> Это лучшее предположениеЯ не могу дать вам, потому что вы не предоставляете ни HTTP-статус ответа, ни ситуацию, в которой выдается исключение. Сообщение об исключении также пусто, так что ...

Answer 2

Почему вы заново изобретаете что-то, что работает нормально.

1-й Токен в лезвии должен выглядеть следующим образом: (у вас есть дополнительный !! по любой причине)

<meta name="csrf-token" content="{{ csrf_token() }}">

2-й Поместите этот код где-нибудь в мастер-клинок:

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
