在Python中，必须出现这种类型的Oauth soap标头

Question

最近，Microsoft撤回了用于访问Exchange服务的基本身份验证服务。因此，我正在努力将身份验证从基本的基于OAUTH转换为基于OAUTH。但是，在测试过程中，我遇到以下例外。

  File "/usr/local/lib/python3.6/site-packages/exchangelib/services/common.py", line 423, in _raise_soap_errors
    raise vars(errors)[code](msg)
exchangelib.errors.ErrorInvalidExchangeImpersonationHeaderData: ExchangeImpersonation SOAP header must be present for this type of OAuth token.

我浏览了此处提到的建议 https：//github.com/eceders.com/ecedersstrand/ecederstrand/exchangelib/exchangelib/sissues/735555 解决问题，但没有运气解决问题。

＃实现有关

redentials = OAuth2Credentials(
            client_id=self.client_id, client_secret=self.client_secret, tenant_id=self.tenant_id,
            identity=Identity(smtp_address=self.email_address)
        )
        log.info(f"Credentials ==>{credentials}")
        config = Configuration(server=self.email_server, credentials=credentials,  auth_type=OAUTH2,  version=Version(build=EXCHANGE_O365))
        self.account = Account(self.email_address, access_type=DELEGATE, config=config)

解决上述例外的任何建议都是很大的帮助。提前致谢

当您使用client_credentials流时，您需要在ews中使用模仿，例如，

access_type=DELEGATE

您

access_type=IMPERSONATION

还需要确保您的申请注册具有FULL_ACCESS_AS_APP许可，并且已同意以查看 https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-to-to-authenticate-an-ews-an-ews-application-by-usish-using-oauth
