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：

#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：

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);  

    }  

}
