c# - Java TCP 客户端不接收从 C# 服务器发送的消息

Question

我正在用 c# 编写一个 tcp 服务器，并用 java 编写相应的客户端。我在本地主机上测试连接，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它们。使用调试器我已验证 stream.Write(...) 已执行。知道问题出在哪里吗？

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以 CR、LF 或 CR/LF 结尾？

readLine 阻塞，直到读取行终止字符。
