使用Python登录到HP ALM时，证书验证失败

如何解决使用Python登录到HP ALM时，证书验证失败

我正在尝试创建一个仪表板，该仪表板将连接到HP ALM。我现在要完成的工作是使用SSL证书通过Python对ALM进行基本身份验证。

ALM版本12.01

HTTPSConnectionPool（host ='#####'，port = ####）：已超过最大重试次数使用网址：＃/ alm-authenticate？％3Calm-authentication％3E％3Cuser％3E #####％3C / user％3E％3Cpassword％3E ####％3C / password％3E％3C / alm-authentication％3E（引起通过SSLError（SSLCertVerificationError（1，'[SSL： CERTIFICATE_VERIFY_Failed]证书验证失败：无法获取本地发行者证书（_ssl.c：1108）'）））

这是我的代码：（某些部分被＃代替以隐藏实际内容）

FsstateBackend

输出：

import ssl
import requests
import urllib3


#function to get certificate from server
def _certificate_required(hostname,port=443):
    pem_cert = ssl.get_server_certificate((hostname,port),ca_certs=None)
    print("Certificate string received")
    return pem_cert

urllib3.disable_warnings()
url = "http://##ALM-url##/qcbin/rest/is-authenticated/"
querystring = {"username":"##User##","password":"##pass##"}
headers = {
'token': "####",}
try:
    response = requests.request("GET",url,headers=headers,params=querystring,verify = "##/certificate.cer")
    print(response.headers)
    new_header = response.headers
    cert=_certificate_required(hostname="##ALM url##",port=443)
    print("Certicate string obtained from server:\n"+cert)
    with open('##/certificate.cer','w') as f:
        f.write(cert)

    print("Certificate updated")
    new_url ="https://##ALM url##/qcbin/authentication-point/alm-authenticate"
    response = requests.request("POST",new_url,headers=new_header,params="<alm-authentication><user>##USER##</user><password>##PASS##</password></alm-authentication>",verify = "##/certificate.cer")
    print(response.text)
    print(response.headers)
    print(response.status_code)
except Exception as e:
    print("Error occured")
    print(e)
