python——http请求

python发送HTTP请求，很简洁：

1. get

import urllib

url="http://www.zhangyue.com"

sock= urllib.urlopen(url)

html = sock.read()

sock.close()

2. post(和get的区别在于是否传参数)

import urllib

url = "http://www.zhangyue.com"

params = urllib.urlencode({'username':'lixinglei'})

sock = urllib.urlopen(url, params)

html = sock.read()

sock.close()
