requests 模拟登陆网站

当我们需要浏览登陆后的网站内容时，就需要模拟登陆网站，为了维持登陆状态，就需要用到session来维持整个会话，requests库中对应的requests.session()便可以帮我们完成这些。

import requests

login_url = "http://www.xxx.com/login"
data = {"username":"admin","password":"letmein"}

headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
    'Accept-Encoding': 'gzip, deflate, sdch',

    'Referer': 'http://www.xxx.com/',

#获取登陆状态下的session
def getSession(URL,DATA,HEADERS):
	_session = requests.session()
	_session.post(URL,data = DATA,headers = HEADERS,verify = False)
	return _session

#访问后面网页的时候就是带着session的登陆状态了
session = getSession(url,data,headers)
res = session.get(url,verify = False) 
print (res.text)
