Question

我正在将wcf rest服务用于angular js应用程序。我试图在角度js应用程序中显示基于账户持有人姓氏的单个记录。当将值发布到wcf服务及其接收值时。检查ado.net代码中的值是否有效或无效。检查值后，它能够在Google Chrome网络点按响应部分中检索帐户持有人信息。但问题是没有在网页中显示任何内容。

这是界面。

 [OperationContract]
    [WebInvoke(Method = "GET",
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json,
    UriTemplate = "/GetCustomers/{Account_Holder_Last_Name}")]
    string GetCustomers(string Account_Holder_Last_Name);

这是实施。

 public string GetCustomers(string Account_Holder_Last_Name)
        {

            List<object> customers = new List<object>();
            string sql = "SELECT * FROM Current_Account_Holder_Details WHERE Account_Holder_Last_Name =@Account_Holder_Last_Name";
            using (SqlConnection conn = new SqlConnection())
            {
                conn.ConnectionString = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
                using (SqlCommand cmd = new SqlCommand(sql))
                {
                    cmd.Parameters.AddWithValue("@Account_Holder_Last_Name", Account_Holder_Last_Name);
                    cmd.Connection = conn;
                    conn.Open();
                    using (SqlDataReader sdr = cmd.ExecuteReader())
                    {
                        if (sdr.HasRows)
                        {
                            while (sdr.Read())
                            {

                                customers.Add(new
                                {
                                    Tittle = sdr["Tittle"],
                                    Account_Holder_First_Name = sdr["Account_Holder_First_Name"],
                                    Account_Holder_Last_Name = sdr["Account_Holder_Last_Name"],
                                    Account_Holder_DOB = sdr["Account_Holder_DOB"],
                                    Account_Holder_House_No = sdr["Account_Holder_House_No"],
                                    Account_Holder_Street_Name = sdr["Account_Holder_Street_Name"],
                                    Account_Holder_Post_Code = sdr["Account_Holder_Post_Code"],

                                    Account_Holder_Occupation = sdr["Account_Holder_Occupation"],
                                    Account_Number = sdr["Account_Number"]



                                });
                            }

                        }

                    }
                    conn.Close();
                }

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

        }

这是脚本代码。

以下是接收值的wcf服务的屏幕截图。

这是屏幕截图谷歌Chrome网络选项卡能够捕获数据和网页不显示数据。
