我做错了什么？
解决方法
您可以使用此方法：
from bs4 import BeautifulSoup
import requests
url = "https://localhost:5001/Account/Login"
session=requests.session()
bfs= BeautifulSoup(session.get(url).content,'html.parser')
csrftoken = bfs.find('input',dict(name='__RequestVerificationToken'))['value']
dfp= bfs.find('input',dict(name="DFP"))["value"]
parameters={
"__RequestVerificationToken":csrftoken,"DFP": dfp,"Username":"user","Password":"pass",}
respons=session.post(url=url,data=parameters)
print(respons.text)
那我们做了什么？
你看，我们必须先创建一个会话 并使用 BeautifulSoup 我可以加载一次页面并拉出 (__RequestVerificationToken,DFP,..) 并使用我们打开的同一会话发送我们的请求。
