python的requests模块实现登

51cto用python的requests模块实现登陆示例代码如下：

-- coding:utf-8 -- import requests import re

client = requests.session() agent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36" header = { "User-Agent": agent }

URL = "http://home.51cto.com/index" def get_xsrf(): #获取xsrf值 response = client.get(URL, headers=header) match_obj = re.search('.name="csrf-token" content="(.?)"', response.text) if match_obj: return match_obj.group(1) else: return ""

def _51cto_login(account, password): #51cto登录 post_url = URL post_data = { "_csrf": get_xsrf(), "LoginForm[username]": account, "LoginForm[password]": password, #虽然抓包分析时post有以下2个参数，但是实际登陆时以下两个参数可有可无 #"LoginForm[rememberMe]": 0, #"login-button": "登 录" } response = client.post(post_url, data=post_data, headers=header) #只有上面认证通过后，请求以下页面才可以看到登陆后的结果 response = client.get(URL) #print response.content print response.text

_51cto_login("填入真实的用户名", "填入真实的密码")
