举例：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import urllib 
import urllib2
  
def main():
	url = "http://www.douban.com"
	#浏览器头
	headers = {'User-Agent':'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'}
	req = urllib2.Request(url=url,headers=headers)
	data = http://www.mamicode.com/urllib2.urlopen(req).read()>
打印出来的内容中，汉字为乱码。解决方法：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import urllib 
import urllib2
import sys 
type = sys.getfilesystemencoding()
    
def main():
	url = "http://www.douban.com"
	#浏览器头
	headers = {'User-Agent':'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'}
	req = urllib2.Request(url=url,headers=headers)
	data = http://www.mamicode.com/urllib2.urlopen(req).read()>
