Laravel現場異常「照亮\會議\ TokenMismatchException」

Question

Laravel 5.1

我偶爾會收到此錯誤，最常登錄在IE11但有時在AJAX調用了。我在我的登錄窗體中有相應的csrf字段，並且我也將它添加到了AjaxSetup函數中。

我認爲它發生在ajax上，因爲用戶在一段時間後回到頁面，並嘗試在會話過期後使用函數。

雖然IE11問題已經被註銷，但IE11問題讓我感到困惑。

1. 如何在會話過期後使用ajax函數時自動重定向到登錄？

2. 如何防止IE11在嘗試登錄時產生此錯誤？

。

您遺漏了ajax請求的CSRF令牌以及表單帖子。確保包含令牌或Web組中間件下的所有路由。

你可以在你的頭文件中創建一個meta標籤。

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

，包括此令牌到你的Ajax調用。 （您的ajax請求可能看起來不同，但應該在數據中有_token。）

var CSRF_TOKEN = $（'meta [name =「csrf-token」]'）。attr（'content'）;

$.ajax({ 
    type: "POST", 
    data: {_token: CSRF_TOKEN, data:data}, 
    dataType: 'JSON', 
    url: "/check", 
    success: function(msg){ 
     //something... 
    }); 
}); 

對於表單文章，您可以在表單中包含以下代碼。

{{ csrf_field() }}
