Python 如何在spyne中建模SOAP远程过程属性？

我有以下SOAP请求，我应该能够处理：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <LogoutNotification xmlns="urn:mace:shibboleth:2.0:sp:notify" type="global">
      <SessionID>
        _d5628602323819f716fcee04103ad5ef
      </SessionID>
    </LogoutNotification>
  </s:Body>
</s:Envelope>

为完整起见，以下是使用的模型：

class OKType(ComplexModel):
    pass


class MandatoryUnicode(Unicode):
    class Attributes(Unicode.Attributes):
        nullable = False
        min_occurs = 1

---

模式是。但是没有包含该属性的正式WSDL。

关键是使用裸体样式。然后，您可以并且需要对完整的输入和输出消息进行建模

我的工作代码如下所示：

class OKType(ComplexModel):
    pass


class MandatoryUnicode(Unicode):
    class Attributes(Unicode.Attributes):
        nullable = False
        min_occurs = 1


class LogoutRequest(ComplexModel):
    __namespace__ = 'urn:mace:shibboleth:2.0:sp:notify'
    SessionID = MandatoryUnicode
    type = XmlAttribute(Enum("global", "local", type_name="LogoutNotificationType"))


class LogoutResponse(ComplexModel):
    __namespace__ = 'urn:mace:shibboleth:2.0:sp:notify'
    OK = OKType


class LogoutNotificationService(Service):
    @rpc(LogoutRequest, _returns=LogoutResponse, _body_style='bare')
    def LogoutNotification(ctx, req):
        # do stuff, raise Fault on error
        # sessionid is available as req.SessionID
        return LogoutResponse

关于的不太相关的问题包含了很好的例子，并向我展示了如何解决这个问题

class OKType(ComplexModel):
    pass


class MandatoryUnicode(Unicode):
    class Attributes(Unicode.Attributes):
        nullable = False
        min_occurs = 1


class LogoutRequest(ComplexModel):
    __namespace__ = 'urn:mace:shibboleth:2.0:sp:notify'
    SessionID = MandatoryUnicode
    type = XmlAttribute(Enum("global", "local", type_name="LogoutNotificationType"))


class LogoutResponse(ComplexModel):
    __namespace__ = 'urn:mace:shibboleth:2.0:sp:notify'
    OK = OKType


class LogoutNotificationService(Service):
    @rpc(LogoutRequest, _returns=LogoutResponse, _body_style='bare')
    def LogoutNotification(ctx, req):
        # do stuff, raise Fault on error
        # sessionid is available as req.SessionID
        return LogoutResponse
