Question

我正在c＃中编写tcp服务器，在java中编写相应的客户端。我正在测试localhost上的连接，客户端能够连接到服务器。但是，当我发送消息时，客户端永远不会收到消息。使用调试器我已经验证了stream.Write（...）的执行。知道问题可能是什么？

这是c＃服务器：

        TcpClient client = (TcpClient)cl;
        NetworkStream stream = client.GetStream();

        byte[] msg = new byte[512];
        int bytesRead; 

        while (running)
        {
            while (messages.getCount() > 0)
            {
                String msg = messages.Take();

                if (cmd != null)
                {
                    byte[] bytes = Encoding.UTF8.GetBytes(msg.ToCharArray());

                    try
                    {
                        stream.Write(bytes, 0, bytes.Length);
                        stream.Flush();
                    }
                    catch (Exception e)
                    {

                    }
                }
            }

            Thread.Sleep(1000); 
        }

Java客户端：

public void run() 
{
    try 
    {
        socket = new Socket(address, port);
        in = new BufferedReader( new InputStreamReader( socket.getInputStream() ));
        out = new PrintWriter(socket.getOutputStream());
        running = true;
    } 
    catch (Exception e){
        e.printStackTrace();
        running = false; 
    } 

    String data;
    while(running)
    {
        try 
        {
            data = in.readLine();

            if(data != null)
            {
                processData(data);
            }
        } 
        catch (IOException e) 
        {
            e.printStackTrace();

            running = false; 
            break;
        }
    }

    try 
    {
        socket.close();
        socket = null;
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    }

    running = false; 
}

您正在使用BufferedReader.readLine()。您的消息字符串是否由CR，LF或CR / LF终止？

readLine阻塞，直到读取行终止字符。

Java TCP Client不接收从C＃Server发送的消息
