import requests
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36 Edg/92.0.902.62"
}
s = requests.session()
r = s.get('http://jd.com/',
headers=headers,
allow_redirects=False)
print (r.status_code)
r_url = r.headers["Location"]
