這篇文章主要介紹了python服務器與android客戶端socket通信的實現(xiàn)方法,實例形式詳細講述了Python的服務器端實現(xiàn)原理與方法,以及對應的Android客戶端實現(xiàn)方法,需要的朋友可以參考下

本文實例講述了python服務器與android客戶端socket通信的方法。分享給大家供大家參考。具體實現(xiàn)方法如下：

首先，服務器端使用python完成，下面為python代碼：

#server.py  

import socket  

def getipaddrs(hostname):#只是為了顯示IP，僅僅測試一下  

    result = socket.getaddrinfo(hostname, None, 0, socket.SOCK_STREAM)  

    return [x[4][0] for x in result]  

host = ''#為空代表為本地host  

hostname = socket.gethostname()  

hostip = getipaddrs(hostname)  

print('host ip', hostip)#應該顯示為：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)#把接收到數(shù)據(jù)原封不動的發(fā)送回去  

    print('Received', repr(data))  

    conn.close()

下面是Android代碼：

復制代碼代碼如下:

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改成你服務器的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);//發(fā)送數(shù)據(jù)  

            out.flush();  

            Log.i("TcpClient", "sent: " + outMsg);  

            //accept server response  

            String inMsg = in.readLine() + System.getProperty("line.separator");//得到服務器返回的數(shù)據(jù)  

            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);  

    }  

}
