阿贾克斯与拉拉维尔错误与路由 - Ajax with Laravel Error with Routing

我在调用 ajax 时遇到了 laravel 的路由问题，但我真的不明白是什么原因造成的，因为我应该调用 ajax 并成功返回。任何帮助将不胜感激。谢谢！

这是我的 ajax 代码

$.ajax({
            type: "POST",
            url: baseLocalUrl, //baseLocalUrl= "http://localhost:4567/admin/menuBuilder/1/save"
            data: 
            {
                html: $("#comment_area").text()
            },
            success: function(data){
                alert("success!");
            }

});

这是我的路线

Route::group(array('prefix' => 'admin', 'before' => 'auth'), function()
{
.....
Route::post('menuBuilder/{role}/save' , array('uses' => 'AdminMenuBuilderController@saveHTML' ));
.....
});

这是我的控制器方法

public function saveHTML($roleId){
        //$decodeJson = Input::get('html');
        return "success";
}

这是我收到的错误

 POST http://localhost:4567/admin/menuBuilder/1/save 500 (Internal Server Error)

您需要在

AJAX 调用的标头中包含 CSRF 令牌。试试这个：

在 HTML <head>块中：

<!-- This is one of the more common ways of accessing your CSRF token. -->
<meta name="csrf-token" content="{{ csrf_token() }}">

对于您的 AJAX 调用：

var token = $('meta[name="csrf-token"]').attr('content');
$.ajax({
  type: "POST",
  url: baseLocalUrl,
  data: {
    html: $("#comment_area").text()
  },
  // Added the CSRF token to the request header.
  header: {"X-CSRF-Token": token},
  success: function(data) {
    alert("Success!");
  }
});

最后，在 app/filters.php 中，将您的 CSRF 过滤器更改为：

Route::filter('csrf', function()
{
  $token = Request::ajax() ? Request::header('X-CSRF-Token') : Input::get('_token');
  if (Session::token() != $token)
  {
    throw new Illuminate'Session'TokenMismatchException;
  }
});
