python - 501 无效请求

问题描述

我正在使用 exchangelib 对我们的邮件系统进行一些端到端的测试。目前，在提出请求时，我收到了 501。

# Tell exchangelib to use this adapter class instead of the default
BaseProtocol.HTTP_ADAPTER_CLS = NoVerifyHTTPAdapter

...

version = Version(api_version="Exchange2013_SP1", build=Build(15, 0, 847))
credentials = Credentials(username=outlook_profile['Username'], password=outlook_profile['Password'])
config = Configuration(server="<SERVICEURL>", credentials=credentials, auth_type=NTLM, version=version)
account = Account(primary_smtp_address="<USER>@<DOMAIN>", config=config, autodiscover=False, access_type=DELEGATE)

print(account.inbox.total_count)

错误：

WARNING:exchangelib.services.common:EWS https://<SERVICEURL>/EWS/Exchange.asmx, account <USER>@<DOMAIN>: Exception in _get_elements: Traceback (most recent call last):
  File "C:\Python38\lib\site-packages\cached_property.py", line 69, in __get__
    return obj_dict[name]

During handling of the above exception, another exception occurred:

Response data: b'<html><head><title>501 Invalid Request</title></head><body>Invalid Request: ??</body>\r\n'

但是，当我使用 powershell EWS 库连接（成功）到我的电子邮件系统时，我可以看到我的请求正文看起来完全不同，尤其是在soap:Envelope标签方面：

POST https://<SERVICEURL>/EWS/Exchange.asmx HTTP/1.1
Content-Type: text/xml; charset=utf-8
Accept: text/xml
User-Agent: ExchangeServicesClient/15.00.0847.030

Authorization: NTLM <HASH>

Content-Length: 673

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Header>
    <t:RequestServerVersion Version="Exchange2013_SP1" />
  </soap:Header>
  <soap:Body>
    <m:GetFolder>
      <m:FolderShape>
        <t:BaseShape>AllProperties</t:BaseShape>
      </m:FolderShape>
      <m:FolderIds>
        <t:DistinguishedFolderId Id="inbox" />
      </m:FolderIds>
    </m:GetFolder>
  </soap:Body>
</soap:Envelope>

此外，如果我改为使用 来定位自动发现 URL exchangelib，我可以正确解析服务器，但仍会收到相同的 501 错误。因此凭据已正确配置。

如果需要，我可以提供其他信息。非常欢迎任何帮助。

更新 1

exchangelib通过拆分请求，我能够正确地验证和查询服务器，而不是使用该模块：

session = requests.Session()
session.mount('https://', adapter)
session.headers.update({'Content-Type': 'text/xml; charset=utf-8', 'Expect': '100-continue'})
session.auth = HttpNtlmAuth(domain\\username, password)
session.post('https://SERVICEURL/EWS/Exchange.asmx', verify=False)
session.post('https://SERVICEURL/EWS/Exchange.asmx', data=body, verify=False)

这是为查询收件箱而生成body的确切请求正文：excahngelib
