Question

我对套接字有点新意，我正在尝试编写一个程序，我基本上可以从Client程序向Server程序发送一些简单的请求。现在我只想在客户端中拥有用户可以选择的1或2个选项。例如，如果用户在客户端中选择“选项1”，则服务器会发回一条消息“您选择选项1”，依此类推，但我无法弄清楚如何读取已从客户端发送的服务器上的输入。

客户代码：

Socket socket = null;

    try
    {
        System.out.println("Connecting to Server");

        socket = new Socket("192.168.0.104", 7003);
        socket.setSoTimeout(10000);
        System.out.println("Connected");

        InputStreamReader input = new InputStreamReader(socket.getInputStream());
        BufferedReader buffer = new BufferedReader(input);
        PrintWriter print = new PrintWriter(socket.getOutputStream(), true);

        String line = buffer.readLine();

        //Not Sure which buffer to user here            
        System.out.println("Option 1");
        System.out.println("Option 2");
        System.out.println("Option 3");
        }

        System.out.println("Closing Client Connection");
        buffer.close();
        input.close();
        print.close();
        socket.close();
        System.exit(0);

服务器代码：

    ServerSocket serverSock = null;
    Socket standSock = null;

    try
    {
        serverSock = new ServerSocket(7003);
        standSock = serverSock.accept();

        InputStreamReader input = new InputStreamReader(standSock.getInputStream());
        BufferedReader read = new BufferedReader(input);
        PrintWriter print = new PrintWriter(standSock.getOutputStream(), true);

        String dateTime = (Calendar.getInstance()).getTime().toString();
        print.println("You're connected to the Server at: " + dateTime);
        print.println("Type Q to disconnect");

        String line = read.readLine();
        //Not sure what to do here
        System.out.println("Client: " + line);
        print.println("Server" + line);


        System.out.println("Closing Server Connection");
        read.close();
        input.close();
        print.close();
        standSock.close();

我需要在Clinet中使用两个不同的BufferedReader，一个用于用户输入，一个用于socket？真的很困惑这个部分。

客户端需要读取用户的输入并将其发送到服务器。服务器需要从套接字读取并响应套接字。客户端必须从套接字读取并向用户提供适当的消息。服务器不会直接通过客户端直接读取或写入任何内容。

套接字通信服务器/客户端
