POST、GET、DELETE操作を受け入れるためにwcf Rest Serviceを作成しました。サーバーにGETリクエストを発行すると、JSONデータは表示されず、[]マークがGoogle Chromeに表示されます。Wcf RestサービスGETメソッド
ここにインターフェイスがあります。
[OperationContract]
[WebInvoke(Method = "GET",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/GetCustomers/{prefix}")]
string GetCustomers(string prefix);
ここに実装があります。
public string GetCustomers(string prefix)
{
List<object> customers = new List<object>();
string sql = "SELECT * FROM Current_Account_Holder_Details WHERE Account_Holder_Last_Name LIKE @prefix + '%'";
using (SqlConnection conn = new SqlConnection())
{
conn.ConnectionString = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlCommand cmd = new SqlCommand(sql))
{
cmd.Parameters.AddWithValue("@prefix", prefix);
cmd.Connection = conn;
conn.Open();
using (SqlDataReader sdr = cmd.ExecuteReader())
{
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));
}
}
