Socket请求获取数据

Posted 2020-09-23 hy战斗吧

用socket连接服务器的时候，需要在子线程进行网络请求，请求完成之后可以通过Handler来处理主线程应该得到的通知（更新view）

private void StartRequestFromSocket(final int mycho) {
    new Thread() {
        public void run() {
            try {
                SendRequest(mycho);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }.start();
}

public void SendRequest(int mycho) {
    String sendString="sendString";
    try {
        socket = new Socket(IpAddress, Port);
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        // 由系统标准输入设备构造BufferedReader对象
        PrintWriter write = new PrintWriter(socket.getOutputStream());
        // 由Socket对象得到输出流，并构造PrintWriter对象
        BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        write.println(sendString);
        write.flush();
        getS = in.readLine();
        System.out.println("Server:" + getS);
        mHandler.sendEmptyMessage(mycho);
    } catch (UnknownHostException e1) {
        e1.printStackTrace();
    } catch (IOException e1) {
        e1.printStackTrace();
    } finally {
        try {
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
