Python 2.7 Python2.7和wcf之间的双工通信

我是WCF的新手。我能够构建一个自托管WCF服务，并使用NetTcpBindings将4.NET应用程序连接到该服务。现在，我需要另外一个用Python2.7脚本编写的客户端来连接到这个提供双工通信的WCF服务

据我在谷歌上搜索，应该使用带有SOAP1.2的WsDualHttpBinding

这是我的服务界面

namespace GPH_QuickMessageServiceLib
{
    /// <summary>
    /// GPH Quick Message Service Operations
    /// </summary>
    [ServiceContract(
        Name = "GPH_QuickMessageService",
        Namespace = "GPH_QuickMessageServiceLib",
        SessionMode = SessionMode.Required,
        CallbackContract = typeof(IMessageServiceCallback))]

    public interface IMessageServiceInbound
    {
        [OperationContract]
        [WebInvoke]
        int JoinTheConversation(string userName);
        [OperationContract]
        [WebInvoke]
        int LeaveTheConversation(string userName);
    }

    public interface IMessageServiceCallback
    {
        [OperationContract(IsOneWay = true)]
        [WebInvoke]
        void NotifyUserJoinedTheConversation(string userName, List<string> SubscriberList);
        [OperationContract(IsOneWay = true)]
        [WebInvoke]
        void NotifyUserLeftTheConversation(string userName, List<string> SubscriberList);
    }
}

我猜，我的python客户机已经绑定到服务器并获取可用操作的列表，但它无法从这些操作中获取结果。它总是不返回任何值

除肥皂水外，我还尝试了其他几种方法，例如，但结果总是为“无”或“0”。我在这些SOAP客户机进程上附加了记录器，并且总是得到“HTTP成功”或“202接受”。我自己也不知道这里到底出了什么问题

有没有人面临同样的问题？请给我一些线索来解决这个问题

或者任何其他在Python2.7和WCF之间实现双工通信的想法都是值得赞赏的
