The way the session sets the initial cookie in requests

If you directly use session.cookies = cookie to assign value, it will prompt
AttributeError: 'dict' object has no attribute 'extract_cookies'

method one

import requests

url = 'http://httpbin.org/get'
s = requests.Session()
cookie_dict = {
    
    
    'a': "aaa",
    'v': "bff",
}
cookie_jar = requests.utils.cookiejar_from_dict(cookie_dict, cookiejar=None, overwrite=True)
s.cookies = cookie_jar
res = s.get(url)
print(res.text)

output

  "args": {
    
    }, 
  "headers": {
    
    
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate",

}
s.cookies.update(cookie_dict)
