Question

以下发布请求失败，出现HTTP错误500，但我不明白为什么。

请求看起来像这样：

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.

请求标头如下：

这是一个ASP.Net MVC应用程序，我的控制器返回该视图，从而触发此发布请求，如下所示：

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

Answer 1

该问题是HTTP错误代码所建议的服务器端问题。

自然地，我在控制器中放置了一个断点，但是在调试时没有碰到断点。

我需要做的是使用IIS Express启动我的Web应用程序，然后才遇到断点，并且我能够调试真正的服务器端问题。
