Question

我想从WCF服务返回CookiesContainer对象，但我无法返回。我可以从服务中返回字符串。

这是我的 Web.config

[ServiceContract]
public interface IService1

    CookieCollection GetCookies();

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

        req.CookieContainer = new CookieContainer();

        req.ServicePoint.Expect100Continue = true;

        return ((HttpWebResponse)req.GetResponse()).Cookies;
    }

    public CookieContainer GetConnect(string uid, string password)
    //public string GetConnect(string uid, string password)
    {

            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;

            else
            {

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

        //}
    }
  }
 }

这是我的 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;
    }

当我从服务中返回CookiesContainer时，我收到以下错误

在 http：// localhost：3922 / Service1.svc 上没有可以接受该消息的端点。这通常是由错误的地址或SOAP操作引起的。有关更多详细信息，请参阅InnerException（如果存在）。

我不明白如何将CookiesContainer对象从服务返回到客户端 anybuddy可以告诉我吗？

Answer 1

如果没有别的，为了帮助调试，我会手动运行序列化。 CookieContainer不是XmlSerializable（但是Soap Serializable真的不应该是问题）但是我从不喜欢发送除了通过webservices写的POCO对象以外的任何东西。

这是我的通用序列化方法，可能只是将其提供给字节数组，或者Convert.ToBase64String()并返回它。如果没有别的，这将绝对确认您的网络服务正在按预期工作。

使用我在下面的方法：

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

试试这个：

在您的客户端项目中，转到服务参考，右键单击，然后点击更新服务参考。每次对服务标志（任何方法或参数）进行更改时，都必须更新此引用。也许你做了一些改变而忘了做这一步。
以防万一，在接口和服务定义中设置params名称等于。注意 interface 中定义的CookieContainer GetConnect(string uname, string password);指定string uname，但 Service1 实现使用CookieContainer GetConnect(string uid, string password);声明string uid。不应该是一个问题，而只是为了整洁。
