发布后发布后返回400错误请求

Question

看到我的POST方法返回400 Bad Request之后，我完全被困住了。奇怪的是，他们在Local上工作得很好。当我发布API项目并将其部署到我们的测试服务器时，POST方法将停止工作。

这是我的web.config文件：

<configuration>

我已在此处IIS hosted WCF Service return HTTP 400 Bad Request和此处ASP.NET Web API "400 Bad Request" on POST Request When Deploying to Test Server尝试了建议的解决方案，但不幸的是，在我的情况下，这些解决方案都不起作用。

最后一点是，当我收到此错误时，Fiddler上的错误消息也完全为空。

{"Message":""}

谢谢！

我将安全标签注释掉，因为它们也不能解决我的问题。

下面是在服务器上返回错误请求，但在本地上可以正常工作的方法：

public HttpResponseMessage PostLogin(LoginWM loginWM)
    {
        try
        {
            if (_userTokenManager.CheckUser(loginWM))
            {
                _userTokenManager.SaveToken(loginWM.Email, loginWM.Password);
                return Request.CreateResponse(HttpStatusCode.Created, _userTokenManager.PublishToken(loginWM.Email, loginWM.Password));
            }
            else
            {
                return Request.CreateErrorResponse(HttpStatusCode.NotFound, new Exception("User not found."));
            }
        }
        catch (Exception ex)
        {
            return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ex.Message);
        }
    }

我要发送的内容（JSON格式）如下：

{"Email":"ozgur@gmail.com","Password":"oa123"}

这是我用于上述JSON的类：

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace XX.XX.Model.WebModel
{
    public class LoginWM
    {
    [Required]
    [StringLength(50)]
    public string Email { get; set; }

    [Required]
    [StringLength(20)]
    public string Password { get; set; }
}
