python使用urllib2实现http代理请求

 1 #coding=gb2312
 2 import urllib2;
 3 proxy_handler = urllib2.ProxyHandler({‘http‘:‘61.184.192.42:80‘});
 4 #此处替换代理IP和端口
 5 opener = urllib2.build_opener(proxy_handler) ;
 6 f=opener.open(‘http://1111.ip138.com/ic.asp‘);
 7 con=f.read();
 8 print con;
 9 start=con.find(‘您的IP是‘);
10 end=con.find(‘</center>‘);
11 print con[start:end];
12 f.close();
