Datatables ajax post请求失败，状态码为500。

Question

下面的帖子请求以HTTP错误500失败，但我看不出原因。

请求看起来是这样的。

var table = table = $('#table-styling').DataTable({
  serverSide: true,
  pageLength: 25,
  processing: true,
  language: {
      loadingRecords: "Loading...",
      processing: "Loading..."
  },
  ajax: {
      url: '/myapplication/myrequest',
      type: 'POST',
      contentType: "application/json;",
      dataType: 'json',
      traditional: true,
      data: function (d) {
          return JSON.stringify(d);
      },
      headers: {
          AntiForgeryToken: $(':input[name="__RequestVerificationToken"]').val()
      }
  },

// etc.  

请求头是这样的

这是一个ASP.Net MVC应用程序，我的控制器返回了视图，它像这样启动了这个post请求。

@section Scripts {
    <script type="text/javascript">
        $(document).ready(function () {
            myscript.function.load();
        });
    </script>
}

Answer 1

问题是，正如HTTP错误代码所提示的那样，是服务器端的问题。

所以我很自然地在我的控制器中放了一个断点，但是在调试的时候并没有打到断点。

我需要做的是用IIS Express启动我的web应用，只有这样断点才被击中，我才能调试出真正的服务器端问题。
