想让host在user-agent的位置,该怎么办?如果不换的话,请求会报500的错误

解决：

import requests
 
Information = requests.Session()
print(Information.headers)
 
Information.headers.update({
    "Accept-Encoding": "identity",
    "Content-Type": "application/x-www-form-urlencoded; charset=utf-8",
    "User-Agent": "Dalvik/2.1.0 (Linux; U; Android 9; Redmi Note 5 MIUI/20.1.16)",
    "Connection": "Keep - Alive",
    "Accept": None
})
print(Information.headers)
 
Information.headers.clear()
Information.headers.update({
    "Accept-Encoding": "identity",
    "Content-Type": "application/x-www-form-urlencoded; charset=utf-8",
    "User-Agent": "Dalvik/2.1.0 (Linux; U; Android 9; Redmi Note 5 MIUI/20.1.16)",
    "Connection": "Keep - Alive",
    "Accept": None
})
print(Information.headers)
关键点在于 "Information.headers.clear()"
