Thrift 双向通信实现（C#版）

主要参考了：Apache thrift RPC 双向通信，但是这篇是用Java写的，和C#会有一些不一样，所以写了一个C#版的。此博客使用Thrift 0.10.0版本，不同版本可能会有差异。
如何在C#中引用Thrift这些就不写了，可以翻我之前的博客，现在开始直接通过代码来说明：
编写Thrift IDL文件
编写一个非常简单的功能，输入一个字符串参数，返回值为空：

//HelloWorldBidirectionService.thriftservice HelloWorldBidirectionService{    oneway void SayHello(1:string msg);}

oneway不能少，具体oneway的含义可查看我之前的博客，这类似一个异步的实现。
编写服务端代码
HelloWorldBidirectionServer实现了Iface接口用于接收客户端消息，并有一个客户端传输层对象集合用于记录所有已连接的客户端。

    //HelloWorldBidirectionServer.cpp    public class HelloWorldBidirectionServer : HelloWorldBidirectionService.Iface    {        public void Run(int port)        {            try            {                TServerTransport transport = new TServerSocket(port);                TTransportFactory transportFac = new TTransportFactory();                TProtocolFactory inputProtocolFactory = new TBinaryProtocol.Factory();                TThreadPoolServer server = new TThreadPoolServer(getProcessorFactory(), transport, transportFac, inputProtocolFactory);                server.Serve();            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);            }        }        public static List<TTransport> TransportCollection = new List<TTransport>();        public void SayHello(string msg)        {            Console.WriteLine(string.Format("{0:yyyy/MM/dd hh:mm:ss} 服务端接收到消息： {1}", DateTime.Now, msg));        }        public void SayToClient(string msg)        {            try            {                foreach (TTransport trans in TransportCollection)                {                    TBinaryProtocol protocol = new TBinaryProtocol(trans);                    HelloWorldBidirectionService.Client client = new HelloWorldBidirectionService.Client(protocol);                    //Thread.Sleep(1000);                    client.SayHello(msg);                    Console.WriteLine("发给了客户端哟");                }            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);            }        }        public TProcessorFactory getProcessorFactory()        {            return new HelloWorldBidirectionProcessor();        }    }

自定义一个Processor，在每次客户端连接的时候就能监听到，并能获取到客户端的传输层对象TTransport。

    public class HelloWorldBidirectionProcessor : TProcessorFactory    {        public TProcessor GetProcessor(TTransport trans, TServer server = null)        {            if (trans.IsOpen)            {                HelloWorldBidirectionServer.TransportCollection.Add(trans);                Console.WriteLine("有客户端上船啦");            }            HelloWorldBidirectionServer srv = new HelloWorldBidirectionServer();            return new global::HelloWorldBidirectionService.Processor(srv);        }    }

客户端代码
首先定义一个可以接收服务端消息的类，里面只有一个实现Iface接口的方法：

    public class HelloWorldBidirectionFace : HelloWorldBidirectionService.Iface    {        public void SayHello(string msg)        {            Console.WriteLine(string.Format("{0:yyyy/MM/dd hh:mm:ss} 收到服务端响应消息 {1}", DateTime.Now, msg));        }    }

实现客户端，ConnectAndListern方法可以与服务端建立连接，并开启客户端端口监听来自服务端的信息。Say方法可将消息发送至服务端。

    public class HelloWorldBidirectionClient    {        static HelloWorldBidirectionService.Client client = null;        public void ConnectAndListern(int port, string ip = "127.0.0.1")        {            //Tsocket: TCP/IP Socket接口            TSocket tSocket = new TSocket(ip, port);            //消息结构协议            TProtocol protocol = new TBinaryProtocol(tSocket);            try            {                if (client == null)                {                    client = new global::HelloWorldBidirectionService.Client(protocol);                    tSocket.Open();//建立连接                    StartListern(tSocket);//启动监听线程                }                //cli.SayHello(msg);                //tSocket.Close();                //cli.Dispose();            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);            }        }        public void Say(string msg)        {            if (client != null)                client.SayHello(msg);        }        void StartListern(TSocket tSocket)        {            Thread t = new Thread(new ParameterizedThreadStart(Run));            t.Start(tSocket);        }        public void Run(object tSocket)        {            HelloWorldBidirectionService.Processor process = new HelloWorldBidirectionService.Processor(new HelloWorldBidirectionFace());            try            {                while (process.Process(new TBinaryProtocol((TSocket)tSocket), new TBinaryProtocol((TSocket)tSocket)))                {                    Console.WriteLine("消息接收完成，等下一波，阻塞中......");                }            }            catch (Exception ex)            {                Console.WriteLine("连接断开..." + ex.Message);            }        }    }
