Python3：如何使用请求正确进行身份验证？尽管使用请求进行身份验证，但仍会打印“ 401需要身份验证”

Question

我正在尝试从URL下载一些json输出。但是，此URL需要LDAP / AD身份验证。我可能会尝试，但无法验证和下载内容：

#!/bin/python3

import requests, json, urllib3, http.client, pprint
from requests.auth import HTTPBasicAuth

class BlockVolumeStatus():
  getResponse = None
  session = None
  sessionResponse = None
  responseJSON = None

  jmxurl = "jmx-server01.domain.abc"
  jmxurlPort = "1006"
  loginURL = "http://" + jmxurl + ":" + jmxurlPort
  jmxAPI = loginURL + "/jmx/"
  username = "jmx@domain.abc"
  password = "Passw0rd"

  urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
  verify="/etc/pki/tls/certs/ca-bundle.trust.crt"

  def GetJMXJson(self):
    self.session = requests.Session()
    response = self.session.head(self.loginURL)
    self.session.headers = response.headers
    self.session.verify = self.verify

    print(self.session.headers)

    try:
      print("loginURL = %s, self.username = %s, self.password = %s " % ( self.loginURL, self.username, self.password ) )
      self.sessionResponse = self.session.get( self.loginURL + "/jmx.html", auth=(self.username,self.password) )
    except requests.exceptions.HTTPError as err:
      raise SystemExit(err)

    print(self.sessionResponse.status_code)
    print(self.sessionResponse.reason)

    if self.sessionResponse.status_code == 200:
        self.getResponse = self.session.get(self.jmxAPI)

        if getResponse.status_code == 200:
            self.responseJSON = agentStatus.json()
        else:
            print(self.getResponse)


    print(self.responseJSON.json())


bvs = BlockVolumeStatus()
bvs.GetJMXJson()

我已经尝试过Google，但似乎无法正确组合请求才能使其正常工作。结果始终如下：

loginURL = http://jmx-server01.domain.abc:1234, self.username = jmx@domain.abc, self.password = Passw0rd
401

我已经尝试了URL，用户并在Chrome中传递。这有效。为确保我不会误输入任何内容，我将其复制并粘贴到了Chrome登录窗口中，并且一切正常。 Chrome中的响应标头如下：

HTTP/1.1 401 Authentication required
Date: Sat, 31 Oct 2020 22:24:17 GMT
Date: Sat, 31 Oct 2020 22:24:17 GMT

Set-Cookie: hadoop.auth=; Path=/; HttpOnly
Cache-Control: must-revalidate,no-cache,no-store
Content-Type: text/html;charset=iso-8859-1
Connection: close

请求标头如下：

GET /jmx.html HTTP/1.1

我要去哪里错了？认为我没有完全理解可能导致我成功的领域之一。
