從WCF服務返回CookiesContainer對象

Question

我想從WCF服務返回CookiesContainer對象，但是我無法返回。我可以從服務返回字符串。

這裏是我的的Web.config

[ServiceContract] 
public interface IService1

    CookieCollection GetCookies(); 

    [OperationContract] 
    CookieContainer GetConnect(string uname, string password); 
    //string GetConnect(string uname, string password);

     req = (HttpWebRequest)WebRequest.Create("http://site5.way2sms.com/"); 
     req.CookieContainer = new CookieContainer(); 
     // req.CookieContainer.Add(cc); 

     req.CookieContainer.Add(cc); 
     req.KeepAlive = true; 

     req.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11"; 
     req.ContentType = "application/x-www-form-urlencoded";

      CookieContainer con = new CookieContainer(); 
      req.CookieContainer = con; 
      req.CookieContainer.Add(GetCookies()); 
      req.KeepAlive = true;

      req.Referer = "http://site5.way2sms.com/content/index.html"; 

      byte[] data = System.Text.Encoding.Default.GetBytes("username=" + uid + "&password=" + password); 
      req.Credentials = new NetworkCredential(uid, password); 
      req.ContentLength = data.Length; 
      req.AllowAutoRedirect = true; 
      req.ServicePoint.Expect100Continue = true; 

      str = req.GetRequestStream(); 
      str.Write(data, 0, data.Length); 
      str.Close(); 


      res = (HttpWebResponse)req.GetResponse(); 

      string iduri = System.Web.HttpUtility.ParseQueryString(res.ResponseUri.Query).Get("id"); 

      if (iduri != "") 
      { 
       return con; 
       //return "Success"; 
      } 
      else 
      { 
       res.Close(); 
       str.Close();

     //} 
     //catch (Exception ex) 
     //{ 

     //} 
    } 
    } 
} 

這裏是我的Login.xaml.cs

private void btnSignin_Click(object sender, RoutedEventArgs e) 
    { 
     string uid = txtUsername.Text.Trim(); 
     string password = txtPassword.Password.Trim(); 

     networkIsAvailable = Checknetwork(); 
     if (networkIsAvailable) 
     { 
      MessageBox.Show("Network Avaliable", "Avaliable", MessageBoxButton.OK); 
      //svc.GetcookiesCompleted += new EventHandler<GetcookiesCompletedEventArgs>(svc_Get_Cookies); 
      //svc.GetcookiesAsync(); 

      txtblockcheck.Visibility = Visibility.Visible; 
      svc.GetConnectCompleted += new EventHandler<GetConnectCompletedEventArgs>(svc_Get_Connected); 
      svc.GetConnectAsync(uid, password); 
     } 
     else 
     { 
      MessageBox.Show("Please check your network", "Warning", MessageBoxButton.OK); 
     } 
    } 


    void svc_Get_Connected(object send, GetConnectCompletedEventArgs e) 
    { 
     CookieContainer con = e.Result; 
    } 

當我從服務回報CookiesContainer我得到這個以下錯誤

有沒有終點在HTTP偵聽：//本地主機：3922 /服務1 .svc可以接受該消息。這通常是由不正確的地址或SOAP操作引起的。有關更多詳細信息，請參閱InnerException（如果存在）。

我不明白我怎麼能從服務返回CookiesContainer對象到客戶端 可以anybuddy告訴我嗎？

Answer 1

如果沒有別的，爲了幫助調試它，我會手動運行序列化。 CookieContainer不是XmlSerializable（但是是可序列化的Soap，所以不應該是真正的問題），但我絕對不喜歡發送除了通過web服務寫入的POCO對象以外的其他東西。

這裏是我的通用序列化方法，可能只是給它的字節數組，或Convert.ToBase64String()並返回。如果沒有別的，這將絕對確認您的web服務按預期工作。

使用方法，我有如下：

public byte[] GetConnect(string uid, string password) 
{ 
    ... 

    if (iduri != "") 
    { 
     return SerializeObject(con); 
    } 
} 

-

void svc_Get_Connected(object send, GetConnectCompletedEventArgs e) 
{ 
    CookieContainer con = DeserializeObject<CookieContainer >(e.Result); 
} 

-

public static byte[] SerializeObject<T>(T obj) 
{ 
    try 
    { 
     using (MemoryStream memoryStream = new MemoryStream()) 
     { 
      BinaryFormatter xs = new BinaryFormatter(); 
      xs.Serialize(memoryStream, obj); 

      return memoryStream.ToArray(); 
     } 
    } 
    catch 
    { 
     return null; 
    } 
} 
public static T DeserializeObject<T>(byte[] xml) 
{ 
    BinaryFormatter xs = new BinaryFormatter(); 
    MemoryStream memoryStream = new MemoryStream(xml); 
    return (T)xs.Deserialize(memoryStream); 
} 

Answer 2

那麼試試這個：

1. 在您的客戶端項目中，轉到您的服務參考號，右鍵單擊，然後點擊更新服務參考。每次您對服務標誌（任何方法或參數）進行更改時，都必須更新此參考。也許你做了一些改變，忘記做這一步。

2. 爲了以防萬一，在接口和服務定義中設置參數名稱等於。注意CookieContainer GetConnect(string uname, string password);在你定義接口指定string uname，但服務1執行聲明CookieContainer GetConnect(string uid, string password);，使用string uid。不應該是一個問題，而只是爲了整潔。
