Java Sockets - 服务器在客户端发送响应后挂起

Question

只是想获取套接字的句柄。服务器和客户端运行在两个不同的程序中。

它们似乎彼此连接良好，但客户端无法正确地将其输出发送到服务器。服务器只是挂起。代码如下:

服务器:

  private ServerSocket serverSocket;
  private Socket client;

  public void run() throws Exception {
     serverSocket = new ServerSocket(20005);
     while(currentState == Game.State.NORMAL) {
      client = serverSocket.accept();
      PrintWriter out = new PrintWriter(client.getOutputStream(), true);
      BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
      String clientInput = in.readLine();

      // Takes the client input string and does some simple game logic that returns a Gson object
      Gson serverResponse = processInput(clientInput);
      out.write(serverResponse.toString());
      out.flush();
    }
  }

客户:

Socket 客户端套接字；

  void run() throws Exception {
    clientSocket = new Socket("192.168.0.24", 20005);
    PrintWriter out;
    BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));

    // Print the state of the game - returns false if state is win or lose.
    while(printState()) {
      out = new PrintWriter(clientSocket.getOutputStream(), true);
      // This method just takes some input from the console
      String clientInput = getInput();

      out.write(clientInput);
      out.flush();

      String serverResponse = in.readLine();

      updateState(serverResponse);
    }
  }
}

正在发生一些潜在的游戏逻辑，但它非常小，应该是无关紧要的。我想我只是误解了一些基本的东西。

谢谢大家。

确保发送换行符以匹配 Server 中的 in.readLine() 语句。

out.write(clientInput + "\n");

从服务器->客户端发送数据时也是如此。
