我正在尝试使用Zeep访问 SOAP Web 服务
有一个公开可用的WSDL和一个测试 WSDL（有一个自签名证书）
我要测试的代码（来自测试站点）是：
from requests import Session
from zeep import Client
from zeep.transports import Transport
from zeep.wsse.username import UsernameToken
import xml.dom.minidom
WS_USER_NAME = '<username>'
WS_PASSWORD = '<password>'
WS_WSDL = 'https://pre.ipddb.org/WS/Services/IpdDownloadService.svc?wsdl'
session = Session()
session.verify = False
transport = Transport(session=session,
operation_timeout=10)
client = Client(wsdl=WS_WSDL,
wsse=UsernameToken(WS_USER_NAME, WS_PASSWORD),
transport=transport)
with client.options(raw_response=True):
response = client.service.Search(strNames='Rick Astley')
xml = xml.dom.minidom.parseString(response._content)
print xml.toprettyxml()
我的回复是：
<?xml version="1.0" ?>

<s:Text xml:lang="es-ES">The message could not be processed. This is most likely because the action 'https://www.ipddb.org/ws/IpdDownloadService/Search' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.</s:Text>

Web 服务的所有者向我提供了一个用户名和密码，所以我知道我需要提供它，但肯定还有一些我遗漏的东西。我相信它与 WSDL 中定义的策略有关，但是 Web 服务在文档方面没有提供任何东西。
我是 SOAP 新手，但是 WSDL 中是否有足够的内容让我弄清楚他们需要什么来遵守政策？
我可以使用Zeep来履行所有政策吗？
我需要从维护 Web 服务的人员那里获得更多信息吗？
