python服务器与android客户端socket通信实例

本文实例讲述了python服务器与android客户端socket通信的方法。分享给大家供大家参考。具体实现方法如下：

首先，服务器端使用python完成，下面为python代码：

复制代码代码如下: #server.py
import socket
def getipaddrs(hostname):#只是为了显示IP，仅仅测试一下
    result = socket.getaddrinfo(hostname, None, 0, socket.SOCK_STREAM)
    return [x[4][0] for x in result]

host = ''#为空代表为本地host
hostname = socket.gethostname()
hostip = getipaddrs(hostname)
print('host ip', hostip)#应该显示为：127.0.1.1
port = 9999     # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host, port))
s.listen(4)
while True:
    conn, addr = s.accept()
    print('Connected by', addr)
    data = conn.recv(1024)
    if not data: break
    conn.sendall(data)#把接收到数据原封不动的发送回去
    print('Received', repr(data))
    conn.close()

下面是Android代码：

复制代码代码如下: import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.net.UnknownHostException;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class TcpClient extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        runTcpClient();
        finish();
    }

    private static final int TCP_SERVER_PORT = 9999;//should be same to the server port
    private void runTcpClient() {
        try {
            Socket s = new Socket("**.**.intel.com", TCP_SERVER_PORT);//注意host改成你服务器的hostname或IP地址
            BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
            BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
            //send output msg
            String outMsg = "TCP connecting to " + TCP_SERVER_PORT + System.getProperty("line.separator");
            out.write(outMsg);//发送数据
            out.flush();
            Log.i("TcpClient", "sent: " + outMsg);
            //accept server response
            String inMsg = in.readLine() + System.getProperty("line.separator");//得到服务器返回的数据
            Log.i("TcpClient", "received: " + inMsg);
            //close connection
            s.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    //replace runTcpClient() at onCreate with this method if you want to run tcp client as a service
    private void runTcpClientAsService() {
        Intent lIntent = new Intent(this.getApplicationContext(), TcpClientService.class);
        this.startService(lIntent);
    }
}
安卓代码中要注意的就是服务器的地址要写对，而且要保证服务器是可以被你的网段访问的。
