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); 
    } 
}

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。
