Question

我正在用Laquvel 5和Jquery ajax开发一个应用程序。我在视图中有一个选项卡面板。当点击一个标签按钮时它正在加载一个初始表单。它加载了jquery ejax而没有任何问题。之后用户可以将数据输入到表单中，当单击“更新”按钮时，数据应使用jquery ajax保存到数据库。基本上没有页面刷新。

虽然之前的ajax表单加载工作，但点击此按钮，页面刷新并显示令牌不匹配异常。我也包含了csrf令牌。无法确定原因是什么。我已将csrf令牌作为元内容包含在内像这样的价值，

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

在jquery ajax代码中，获得这样的值。

var CSRF_TOKEN=$('meta[name="csrf-token"]').attr('content');

以下是Laravel堆栈跟踪，

Answer 1

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

在文档中。

Answer 2

php artisan clear-compiled

通过访问ajax请求中的{{csrf_token（）}}，将csrf_token包含在请求中。
