cookie绕过验证码登录博客园

代码如下：

# coding:utf-8
import requests

import urllib3
#禁用安全请求警告，适用py3
urllib3.disable_warnings()

url = "https://passport.cnblogs.com/user/signin"

#头信息通过fiddler抓包

headers = {
         "User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0"
}
s=requests.session()       
r = s.get(url, headers=headers, verify=False)
print("======start======")
print(s.cookies)
print("======end======")

#手动登录一次博客园，抓取cookies信息。

c=requests.cookies.RequestsCookieJar()

#添加cookie信息
c.set(".CNBlogsCookie","2DAE0BF85DA417E1EA06A8D7193D46B9D470A2833540FB57D7EFC5CAC8E195A050AD021EE8DA02C23C82F9D434AB388D6581E640892999A0F68C5957225BF66E9B2F31A5E89BF03E8BE8AB8E95B9465197A00B9F")
