WebApi Post方法总是返回'请求的资源不支持http方法'状态:405方法不允许

我创建了一个简单的web api服务GET &POST用户数据。

一切都很好在Localhost。但是当我在服务器上托管服务时，当我从邮差/浏览器调用它时，Get方法工作正常。但是Post方法总是返回"请求的资源不支持http方法'GET'。"状态:405 Method Not Allowed。

有一件事我在这里感到困惑，即我请求POST调用，但状态信息显示我'GET'错误。为什么会这样呢?如果是CORS问题?我通过在应用程序级别(Web)的互联网上搜索答案，尝试了CORS启用各种场景/方面。配置以及Nuget包管理器Cors)。仍然得到405方法不允许。下面粘贴我的API代码:
