python解决urllib2乱码问题

示例：

#!/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 = urllib2.urlopen(req).read()
  print data
  return 0

if __name__ == '__main__':
  main()

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 = urllib2.urlopen(req).read()
  print data.decode("UTF-8").encode(type)
  return 0

if __name__ == '__main__':
  main()
