无法识别 URL 意外以 '/$metadata' 结尾的请求格式

Question

以为我会尝试看看是否有人看过这个或类似的东西，因为我不确定从哪里开始寻找。我有一堆网络服务，它们在很长一段时间内都很好，但现在我的服务器人员说他们给出了一个我以前从未见过的错误。有什么想法/东西要看吗？

您所需要的只是将以下内容添加到您的 web.config 中

<configuration>
  <system.web>
    <webServices>
      <protocols>
        <add name="HttpGet"/>
        <add name="HttpPost"/>
      </protocols>
    </webServices>
  </system.web>
</configuration>

我的网络服务也记录Event Code 3005 .我使用 JQuery $.ajax() 调用我的 Web 服务，它会产生两个 http 请求。第一个请求是"选项"请求，它会遇到一条500 Internal Server Error消息。这是用Event Code 3005记录的那个。第二个请求是"POST"请求，它会遇到来自 Web 服务的正确答案。

我试图防止"OPTIONS"请求被记录为错误并没有成功，但我希望这些信息对您有所帮助。

我的错误日志也与您的短语匹配：
