requests cookies模擬登錄遇到問題

如題，嘗試使用cookies模擬登錄www.jianshu.com，但是沒有成功，來這里像找點思路。

模擬的過程：f12，network找到cookies，cookies有點多，先一股腦全加進(jìn)去，發(fā)現(xiàn)不行。
由于掌握的還是比較基本的操作，一時想不到為什么，怎么做，求解，給個思路就行。

代碼：

import requests
import re
import json

session = requests.Session()
with open('cookies.json','r') as f:
    cookies = json.load(f)

requests.utils.add_dict_to_cookiejar(session.cookies, cookies)

url = 'https://www.jianshu.com/wallet'
session.headers = {
    "User-Agent":"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/66.0.3359.139 Chrome/66.0.3359.139 Safari/537.36",

}
r = session.get(url)
username = re.search('<a class="name" href="[^"]+">(.*?)</a>',r.text)
if not username:
    print(r.text)
else:
    print(username.group(1))
