python - Python 连接到 Exchange /w Windows 身份验证

问题描述

我正在尝试在 Python 3.8脚本中创建一个脚本，该脚本可以连接到Exchange服务器并从邮箱中检索电子邮件。我正在尝试使用当前经过身份验证的用户对Exchange进行身份验证。如果我使用用户名和密码，我可以很好地进行身份验证。（尽量不存储任何密码或任何东西，只需使用当前经过身份验证的用户。）

我正在使用Python 3.8和Exchangelib连接Exchange，但无法弄清楚如何使用 Windows Auth（如果可能）。

任何帮助尝试实现这一点表示赞赏。

谢谢

我正在尝试做的示例：

from exchangelib import DELEGATE, IMPERSONATION, Account, Credentials, OAuth2Credentials, \
    OAuth2AuthorizationCodeCredentials, FaultTolerance, Configuration, NTLM, GSSAPI, SSPI, \
    OAUTH2, Build, Version
from exchangelib.autodiscover import AutodiscoverProtocol

exchange_email = 'mailboxIWantToAccess@domain.com'

account = Account(exchange_email, autodiscover=True)
# account = Account(exchange_email, credentials=credentials, autodiscover=True)

account.root.refresh()
account.public_folders_root.refresh()

print(account.root.tree())

我得到的错误：

解决方案

我在 Windows/Exchangeserver 环境中使用 exchangelib，这是我的登录代码：

import getpass
from exchangelib import Configuration
from exchangelib import Credentials, Account

def login():
    email = 'user@domain.com'
    passwd = getpass.getpass(prompt='Password: ')
    user_credentials = Credentials(email, passwd)
    config = Configuration(server='exchangeserver',
                           credentials=user_credentials)
    account = Account(primary_smtp_address=email, config=config,
                           credentials=user_credentials, autodiscover=False) #maybe try =True
    return account

def main():
    user_account = authenticate()
    print(user_account.root.tree()) #printing the inbox

main()
input('Press enter to exit')
