使用Python/Sypn时找不到Quickbooks Web Connector SOAP请求的资源

Question

我正试图编写一个pythonweb服务来与quickbookswebconnector集成。Im使用spyneapi来实现这一点，但似乎遇到了一个无法识别请求的方法的问题。我写的代码是：

class QuickbooksSOAPService(ServiceBase):
    __tns__ = 'http://developer.intuit.com'

    @srpc(Unicode, Unicode, _returns=Array(Unicode), 
            _operation_name="http://developer.intuit.com/authenticate")
    def authenticate(strUserName, strPassword):

        print strUserName
        return ['','','','']

application = Application(
    [QuickbooksSOAPService], tns='http://developer.intuit.com',
    in_protocol = Soap11(),
    out_protocol = Soap11(),
    )

wsgi_application = WsgiApplication(application)

我通过Flask框架发布这些web服务，我在我的网站的其余部分都使用这个框架

我注意到spyne生成的wsdl定义与官方wsdl的定义存在一些差异，例如：

间谍：

<wsdl:operation name="http://developer.intuit.com/authenticate">
    <soap:operation soapAction="http://developer.intuit.com/authenticate" style="document"/>
    <wsdl:input name="authenticate">
        <soap:body use="literal"/>
    </wsdl:input>
    <wsdl:output name="authenticateResponse">
        <soap:body use="literal"/>
    </wsdl:output>
</wsdl:operation>

正确的intuit版本：

<wsdl:operation name="authenticate">
    <soap:operation soapAction="http://developer.intuit.com/authenticate" style="document"/>
    <wsdl:input>
        <soap:body use="literal"/>
    </wsdl:input><wsdl:output>
        <soap:body use="literal"/>
    </wsdl:output>
</wsdl:operation>

以下是调试日志中弹出的内容

SOAP操作名和SOAP操作名之间的差异是否会导致“找不到请求的资源”问题？还是我错过了更明显的东西？在
