WCF RESTful 서비스, 서버는 의미있는 응답

Question

내가 오류가 계속, WCF를 사용하여 편안한 서비스를 생성하고 제공하지 않았다

이

서버는 의미있는 답변을 제공하지 않았다을; 이는 계약 불일치, 조기 세션 종료 또는 내부 서버 오류로 인해 발생할 수 있습니다.

이것은 사용자 이름과 현재 시간을 가져 와서 로그 인/아웃을위한 데이터베이스에 저장하는 시간 시계 응용 프로그램입니다.

저는 REST 세계에 처음 오신 분 누구도 도와 드릴 수 있습니까?

내 서비스 인터페이스 :

ServiceContract(Namespace:="WCFRESTService")> _ 
Public Interface IService1 

<OperationContract()> _ 
<WebInvoke(UriTemplate:="/login", Method:="PUT")> _ 
Function InsertUserDetails(ByVal username As String, ByVal time As DateTime) As String 
End Interface 

서비스 코드 :

<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Required)> _ 
<ServiceBehavior(Namespace:="WCFRESTService")> _ 
Public Class Service1 
    Implements IService1 

    Private con As New SqlConnection("Data Source=TE-LAPTOP-001\SQL2008R2;Initial Catalog=timeClock;Integrated Security=True") 

    Public Function InsertUserDetails(ByVal username As String, ByVal time As DateTime) As String Implements IService1.InsertUserDetails 

     Dim strMessage As String = String.Empty 
     Dim errorMessage As String = String.Empty 
     Dim numcount As Integer = 0 

     numcount = getusercount(username) 
     If (numcount = 0) Then 

      Try 


       con.Open() 
       Dim cmd As New SqlCommand("spInsertLog", con) 
       cmd.CommandType = CommandType.StoredProcedure 

       cmd.Parameters.AddWithValue("@username", username) 
       cmd.Parameters.AddWithValue("@timein", time) 


       cmd.ExecuteNonQuery() 


      Catch ex As Exception 
       errorMessage = ex.ToString 
      Finally 
       con.Close() 
      End Try 

      strMessage = "You have Signed In at: " + time 
     ElseIf (numcount = 1) Then 

      strMessage = "Error: You need to SignOut before you can SignIn" 
     End If 


     Return errorMessage + strMessage 
    End Function 

    Public Function getusercount(ByVal username As String) As Integer 
     Dim count As Int32 = 0 
     Try 
      con.Open() 
      Dim cmd As New SqlCommand("spgetcount", con) 
      cmd.CommandType = CommandType.StoredProcedure 

      cmd.Parameters.AddWithValue("@username", username) 
      count = Convert.ToInt32(cmd.ExecuteScalar()) 


     Catch ex As Exception 
     Finally 
      con.Close() 
     End Try 


     Return count 
    End Function 
End Class

당신은 (클라이언트의 같은 종류의) 여기 REST 필요가 없습니다. 은 그러나 당신이 원하는 경우 - 사용 스트림을 시도 REST 방식에서에서 WebGet이-응답 :

[OperationContract, WebGet(UriTemplate = "/SendMessage?login={login}&password={password}&phoneNum={phoneNum}&message={message}", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]  
System.IO.Stream SendMessage(string login, string password, string phoneNum, string message, TimeSpan timeout); 
//.. 

public Stream SendMessage(string login, string password, string phoneNum, string message, TimeSpan timeout) 
{ 
//.. 
return new MemoryStream(Encoding.Default.GetBytes(jsonString)); 
}
