这篇文章主要介绍了python服务器与android客户端socket通信的实现方法,实例形式详细讲述了Python的服务器端实现原理与方法,以及对应的Android客户端实现方法,需要的朋友可以参考下

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); 

	    } 

	}
