Laravel中的AJAX調用返回Http異常

Question

當我嘗試在laravel中使用ajax時，顯示以下錯誤，

{“ message”：“”，“ exception”：“ Symfony \\ Component \\ HttpKernel \\ Exception \\ HttpException”，“ file”：“ C：\\ xampp \\ htdocs \\ TravelAssistant \\ vendor \\ laravel \\ framework \\ src \\ Illuminate

我的控制器代碼是

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

阿賈克斯電話，

<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>

帶有csrf令牌的元標記，

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

路由文件web.php條目，

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

我想我被困住了，請幫忙。

Answer 1

為什么要重新發明行之有效的東西。

刀片中的第一個令牌應如下所示：（無論出於何種原因，您都有額外的!!）

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

2nd將此代碼放在主刀片中的某個位置：

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

Answer 2

好的，除了CSRF元標記的方式外，其他一切看起來都不錯，因為您不需要轉義csrf令牌中的任何內容，因此打印令牌的正確方法將是： <!-- CSRF Token --> <meta name="csrf-token" content="{{ csrf_token() }}"> Token- <!-- CSRF Token --> <meta name="csrf-token" content="{{ csrf_token() }}">這是我無法給您的最佳猜測，因為您沒有提供響應的HTTP狀態是什么，也不提供拋出異常的哪種情況，異常消息也為空所以..
