使用ZSI Python中的Web服务客户端 - “无类别结构并没有得到大辞典”
题
我想写使用ZSI一个简单的Web Service Python中的示例客户端。 Web服务的WSDL是以下内容:
<?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>
每次运行以下代码:
from ZSI.ServiceProxy import ServiceProxy
service = ServiceProxy('test.wsdl')
service.NewOperation('test')
我接收:
(...)
/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
我已搜查谷歌的这个错误,我发现描述类似的问题,但没有回答一些文章。你知道是错了吗?有没有在WSDL的错误,我怀念的东西在代码或有一个bug在ZSI?
感谢您提前为您有所帮助: - )
解决方案
最后,我已经找到了解决方案。
我应该运行是这样的:
from ZSI.ServiceProxy import ServiceProxy
service = ServiceProxy('test.wsdl')
service.NewOperation(NewOperationRequest='test')
该问题的原因是,该参数的名称缺失(原文如此!) - 傻误差; - )
