Question

我正在开发wcf休息服务，我将它用于角度js应用程序。我正在尝试根据帐号检索用户帐户信息。当我使用帐号调用方法形式的本地主机时，我以jSON格式从sql数据库获取数据。但是，当我尝试从角度js应用程序调用该方法时，我在Google Chrome控制台窗口中出现以下错误，并且未在网页中显示数据。

获取http://localhost:52098/HalifaxIISService.svc/GetAccountDetails?Account_Number15 404（未找到）。

我检查网络标签及其在响应部分中的显示结束点未找到。

这是界面。

    [OperationContract]
   [WebInvoke(Method = "GET",
   RequestFormat = WebMessageFormat.Json,
   ResponseFormat = WebMessageFormat.Json,
   //BodyStyle = WebMessageBodyStyle.Bare,
    UriTemplate = "/GetAccountDetails/{Account_Number}")]
    string  GetAccountDetails(string Account_Number);

这是实施。

 public string GetAccountDetails(string Account_Number)
        {
                //Convert.ToInt32(Account_Number);
            List<object> customers = new List<object>();
            string sql = "SELECT * FROM Current_Account_Details WHERE Account_Number=@Account_Number";
            using (SqlConnection conn = new SqlConnection())
            {
                conn.ConnectionString = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
                using (SqlCommand cmd = new SqlCommand(sql))
                {
                    cmd.Parameters.AddWithValue("@Account_Number",Account_Number);
                    cmd.Connection = conn;
                    conn.Open();
                    using (SqlDataReader sdr = cmd.ExecuteReader())
                    {
                        while (sdr.Read())
                        {

                            customers.Add(new
                            {
                                Account_Number = sdr["Account_Number"],
                                Account_Creation_Date = sdr["Account_Creation_Date"],
                                Account_Type = sdr["Account_Type"],
                                Branch_Sort_Code = sdr["Branch_Sort_Code"],
                                Account_Fees = sdr["Account_Fees"],
                                Account_Balance = sdr["Account_Balance"],
                                Over_Draft_Limit = sdr["Over_Draft_Limit"],




                            });
                        }
                    }
                    conn.Close();
                }

                return (new JavaScriptSerializer().Serialize(customers));
            }

        }
    }
}

这是脚本代码。

var app = angular.module("WebClientModule", [])
    .controller('Web_Client_Controller', ["$scope", 'myService', function ($scope, myService) {
        var Account_Number = $scope.Account_Number;
        $scope.search = function (Account_Number) {
            var promiseGetSingle = myService.getbyAccount_Number(Account_Number);

            promiseGetSingle.then(function (pl) {
                var res = pl.data;
                $scope.Account_Number = res.Account_Number;
                $scope.Account_Creation_Date = res.Account_Creation_Date;
                $scope.Account_Type = res.Account_Type;
                $scope.Branch_Sort_Code = res.Branch_Sort_Code;
                $scope.Account_Fees = res.Account_Fees;
                $scope.Account_Balance = res.Account_Balance;
                $scope.Over_Draft_Limit = res.Over_Draft_Limit;

                //   $scope.IsNewRecord = 0;
            },
                function (errorPl) {
                    console.log('failure loading Employee', errorPl);

                });
        }

    }]);




app.service("myService", function ($http) {

        this.getbyAccount_Number = function (Account_Number) {
            return $http.get("http://localhost:52098/HalifaxIISService.svc/GetAccountDetails?Account_Number" + Account_Number);
        };

   })

这是HTML。
