Question

我使用jquery（ajax）连接到返回字符串的Web服务，它不能与我合作。它总是去错误功能。这是我的网络服务：

SELECT A1.ID_USER,
       A1.CNAME,
      (SELECT CNAME
           FROM
             (SELECT CNAME,
                     COUNTER
              FROM
                (SELECT id_Category AS IDCATEGORT,
                        COUNT(*) AS COUNTER
                 FROM gamescateg
                 WHERE id_game IN
                     (SELECT ID_GAME
                      FROM UserGames
                      WHERE id_user=UsersGamers.ID_USER --replaced A2 with UsersGamers
                      )
                 GROUP BY id_Category
                )
              JOIN Categories ON id_Category =IDCATEGORT
              ORDER BY COUNTER DESC
             )
           WHERE rownum = 1
        ) AS FAVORITECATEGORY
FROM UsersGamers A1
JOIN UsersGamers A2 ON A1.ID_USER= A2.ID_USER

这是我的js代码：

 [HttpGet]
        [ActionName("GetImage")]
        public string GetImage(string base64String, string imgName,string reqTitle , string reqSubject, string reqStatus,string Creator , DateTime creationdate )
        {

            try
            {
                using (PhMobAppEntities context = new PhMobAppEntities())
                {
                    ClaimsApproval _ca = new ClaimsApproval();
                    _ca.imageBasestrg = base64String;
                    _ca.imageName = imgName;
                    _ca.Creator = Creator;
                    _ca.CreationTime = creationdate;
                    _ca.ReqStatus = reqStatus;
                    _ca.ReqTitle = reqTitle;
                    _ca.ReqSubject = reqSubject;
                    context.ClaimsApprovals.Add(_ca);
                    context.SaveChanges();
                    return "Success";
                }

            }
            catch (DbEntityValidationException ex)
            {

                var errorMessages = ex.EntityValidationErrors
                        .SelectMany(x => x.ValidationErrors)
                        .Select(x => x.ErrorMessage);

                var fullErrorMessage = string.Join("; ", errorMessages);

                var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);

                throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);
            }
        }

当我在高级休息客户端测试我的网络服务时运行正常，请提供建议。

我尝试连接到您的网络服务，我得到以下回复：

{"$id":"1","Message":"No HTTP resource was found that matches the request URI 'http://41.128.183.109:1212/api/Data/GetImage'."}

我认为你的c＃代码存在内部问题，可能与您的路由有关。你的javascript调用可能工作正常，但你只传递一个参数，“test”，而你的声明中还有更多。

你得到什么http响应代码？
