在$ http.post請求上獲取錯誤消息

Question

我收到此錯誤消息：'對象引用未設置為對象的實例。

服務端：

[OperationContract]
[WebInvoke(UriTemplate = "user_login/", Method = "POST", ResponseFormat = WebMessageFormat.Json)]
UserBase UserLogin(UserBase value);

public UserBase UserLogin(UserBase value)
{
    UserLogic UserLg = new UserLogic();
    value = UserLg.GetUser(value);
    return value;
}

客戶端：

var DTO = {
              user_email: "v@prova.it",
              user_pass: "v"
          }

          var deferred = $q.defer();
          $http.post(constants().user_login, DTO
               )
                  .success(function (d) {
                      data = d;
                      $timeout(function () {
                          $rootScope.$broadcast('userLoggedIn');
                      });
                      deferred.resolve(d);
                  })
                  .error(function(data, status, headers, config) {

                  });

在本地主機上，一切正常。 但是將項目上傳到外部服務器的IIS之后，出現下一個錯誤：

在那里，當我打開閑雜人之后，別無他法。 我檢查了服務器日志，但沒有找到有趣的東西...請幫助。

在System.ServiceModel.Dispatcher.MessageRpc.Process（Boolean isOperationContextSet）
