我正在尝试使用ZSI为简单的Web服务在Python中编写示例客户端。 Web服务WSDL如下:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.example.org/test/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="test" targetNamespace="http://www.example.org/test/">
<wsdl:message name="NewOperationRequest">
<wsdl:part name="NewOperationRequest" type="xsd:string"/>
</wsdl:message>
<wsdl:message name="NewOperationResponse">
<wsdl:part name="NewOperationResponse" type="xsd:string"/>
</wsdl:message>
<wsdl:portType name="test">
<wsdl:operation name="NewOperation">
<wsdl:input message="tns:NewOperationRequest"/>
<wsdl:output message="tns:NewOperationResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="testSOAP" type="tns:test">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="NewOperation">
<soap:operation soapAction="http://www.example.org/test/NewOperation"/>
<wsdl:input>
<soap:body namespace="http://www.example.org/test/" use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body namespace="http://www.example.org/test/" use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="test">
<wsdl:port binding="tns:testSOAP" name="testSOAP">
<soap:address location="http://localhost/test"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
每次我运行以下代码:
from ZSI.ServiceProxy import ServiceProxy
service = ServiceProxy('test.wsdl')
service.NewOperation('test')
我收到:
(...)
/var/lib/python-support/python2.5/ZSI/TCcompound.pyc in cb(self, elt, sw, pyobj, name, **kw)
345 f = lambda attr: pyobj.get(attr)
346 if TypeCode.typechecks and type(d) != types.DictType:
--> 347 raise TypeError("Classless struct didn't get dictionary")
348
349 indx, lenofwhat = 0, len(self.ofwhat)
TypeError: Classless struct didn't get dictionary
我已经在Google上搜索了此错误,但发现几则帖子描述了类似的问题,但没有答案。你知道这是错的吗? WSDL中是否有错误,我是否错过了代码中的某些内容,或者ZSI中有错误?
预先感谢您的帮助:-)
最佳答案
最后,我找到了解决方案。
我应该这样跑:
from ZSI.ServiceProxy import ServiceProxy
service = ServiceProxy('test.wsdl')
service.NewOperation(NewOperationRequest='test')
问题的原因是缺少参数名称(原文如此!)-愚蠢的错误;-)
