Python连接到Exchange/w Windows身份验证

您现在位置:Python中文网/ 问答频道 /正文

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服务器并从邮箱检索电子邮件。我正在尝试使用当前已验证的用户通过Exchange进行验证。如果我使用用户名和密码,我可以很好地进行身份验证。(尝试不存储任何密码或任何内容,只需使用当前经过身份验证的用户。)

我正在使用Python 3.8Exchangelib连接Exchange,但无法确定如何使用Windows Auth(如果可能)

为实现这一目标而提供的任何帮助都将不胜感激

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())

我得到的错误是:

Traceback (most recent call last):
  File "c:/Users/jk354/Documents/git.ourgitserver.com/client-info/script-ex.py", line 233, in <module>
    account = Account(exchange_email, autodiscover=True)

说去他妈的,然后换成C。 我正在使用EWS管理的API

https://docs.microsoft.com/en-us/exchange/client-developer/exchange-web-services/get-started-with-ews-managed-api-client-applications

我可以通过以下线路使用当前经过身份验证的用户连接到Exchange:

service.UseDefaultCredentials = true;

终于为我工作了

from requests_kerberos import HTTPKerberosAuth
from exchangelib import DELEGATE, Account, Credentials, Configuration
import exchangelib.autodiscover


def auth_model(**kwargs):
    #get kerberos ticket 
    return HTTPKerberosAuth()


def connect(server, email, username, password=1):
    from exchangelib.protocol import BaseProtocol, NoVerifyHTTPAdapter
    # Care! Ignor Exchange self-signed SSL cert
    BaseProtocol.HTTP_ADAPTER_CLS = NoVerifyHTTPAdapter

    # fill Credential object with empty fields    
    creds = Credentials(
        username="",
        password=""
    )

    # add kerberos as GSSAPI auth_type
    exchangelib.transport.AUTH_TYPE_MAP["GSSAPI"] = auth_model

    # Create Config
    config = Configuration(server=server,credentials=creds, auth_type="GSSAPI")
    # return result
    return Account(primary_smtp_address=email, autodiscover=False, config = config, access_type=DELEGATE)

def main():
    # Connection details
    server = 'mail.domain.ex'
    email = 'person@domain.ex'
    username = 'domain\person'
    account = connect(server, email, username)

    for item in account.inbox.all().order_by('-datetime_received')[:100]:
        print(item.subject, item.sender, item.datetime_received)

main()

我正在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')
