Python请求没有HttpNtlmAuth身份验证对象

Question

我已经尝试了所有方法，但是可以解决HttpNtlmAuth错误

import requests
from requests_ntlm import HttpNtlmAuth
ntmlauth = HttpNtlmAuth('DOMAIN\\USERNAME',PASSWORD)
r=requests.get(url,auth=ntmlauth)
url = "http://someinternalservice"
r

输出

r => <Response [502]>
r.history => []
r.request.headers => {'User-Agent': 'python-requests/2.22.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'Keep-Alive'}

我的请求没有身份验证对象任何帮助
