Zeep SOAP 签名，安全策略

如何解决Zeep SOAP 签名，安全策略

我正在尝试向服务发布正确的请求。

这是它的 WSDL

这是我的代码

    session = Session()
    # session.verify = False
    signature = Signature(
            key_file=private_key,certfile=certificate,# optional_password
    )

    timestamp_token = WSU.Timestamp()
    today_datetime = datetime.datetime.today()
    expires_datetime = today_datetime + datetime.timedelta(minutes=10)
    timestamp_elements = [
        WSU.Created(today_datetime.strftime("%Y-%m-%dT%H:%M:%SZ")),WSU.Expires(expires_datetime.strftime("%Y-%m-%dT%H:%M:%SZ"))
    ]
    timestamp_token.extend(timestamp_elements)

    client = Client(
        wsdl=wsdl,settings=Settings(strict=False,xml_huge_tree=True),wsse=[timestamp_token,signature],transport=Transport(session=session)
    )

    response = client.service.verarbeiteXKfz(
        **params_0707,)

这是我得到的错误

Traceback (most recent call last):
  File "main.py",line 92,in <module>
    main()
  File ".venv/lib/python3.9/site-packages/click/core.py",line 829,in __call__
    return self.main(*args,**kwargs)
  File ".venv/lib/python3.9/site-packages/click/core.py",line 782,in main
    rv = self.invoke(ctx)
  File ".venv/lib/python3.9/site-packages/click/core.py",line 1066,in invoke
    return ctx.invoke(self.callback,**ctx.params)
  File ".venv/lib/python3.9/site-packages/click/core.py",line 610,in invoke
    return callback(*args,**kwargs)
  File "main.py",line 78,in main
    response = client.service.verarbeiteXKfz(
  File ".venv/lib/python3.9/site-packages/zeep/proxy.py",line 46,in __call__
    return self._proxy._binding.send(
  File ".venv/lib/python3.9/site-packages/zeep/wsdl/bindings/soap.py",line 123,in send
    envelope,http_headers = self._create(
  File ".venv/lib/python3.9/site-packages/zeep/wsdl/bindings/soap.py",line 98,in _create
    envelope,http_headers = wsse.apply(envelope,http_headers)
AttributeError: 'lxml.etree._Element' object has no attribute 'apply'

鉴于参数现在通过 zeep 验证（即它们匹配操作的签名），我相信问题出在其他地方。

例如，我认为 WSDL 突出显示很重要

<wsp:Policy xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:sp="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702" wsu:Id="AsymmetricSignaturePolicy">
<!--  ! ! ! ! ! ! ! !   -->
<!--  Important  -->
<!--  ! ! ! ! ! ! ! !   -->
<!--  You have to use {http://www.w3.org/2001/04/xmldsig-more#rsa-sha256}  -->
<!--  as signature algorithm. Since this is not part of the ws-policy specification  -->
<!--  you have to take care about this at application level  -->
<!--  Any other signature algorithm will be rejected!  -->

这是问题吗？我怎样才能做到这一点？

我现在尝试改用 BinarySignature，但它产生相同的错误，即使它具有 apply 方法

跟进：

我现在已经将 Signature 子类化为

class IkfzSignature(Signature):

    def apply(self,envelope,headers):
        security = utils.get_security_header(envelope)

        timestamp_token = WSU.Timestamp()
        creation = datetime.now()
        expiration = creation + timedelta(seconds=61)
        timestamp_token.append(WSU.Created(utils.get_timestamp(creation)))
        timestamp_token.append(WSU.Expires(utils.get_timestamp(expiration)))
        security.append(timestamp_token)

        # headers['Content-Type'] = 'application/soap+xml;charset=UTF-8'
        return envelope,headers

    def verify(self,envelope):
        pass

我现在收到时间戳错误：

raise Fault(
zeep.exceptions.Fault: A security error was encountered when verifying the message Caused by: Invalid timestamp: The message timestamp is out of range

这个问题仍然悬而未决，因为我忽略这是由于时间戳以一种方式或另一种方式设置错误（签名或“值”）
