python的requests模块实现登陆示例
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": account,
"LoginForm": 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": 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")
