[英]nullable WSDL message part?
問題:
我有一個帶有以下簡化WSDL的SOAP服務:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="http://new.webservice.namespace" targetNamespace="http://new.webservice.namespace">
<wsdl:types>
<xs:schema targetNamespace="http://new.webservice.namespace" elementFormDefault="qualified"/>
</wsdl:types>
<wsdl:message name="NewMessageRequest">
<wsdl:part name="parameter" type="xs:string"/>
</wsdl:message>
<wsdl:message name="NewMessageResponse">
<wsdl:part name="result" type="xs:string"/>
<wsdl:part name="param2" type="xs:string"/>
</wsdl:message>
<wsdl:portType name="NewPortType">
<wsdl:operation name="NewOperation">
<wsdl:input message="tns:NewMessageRequest"/>
<wsdl:output message="tns:NewMessageResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="NewBinding" type="tns:NewPortType">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="NewOperation">
<soap:operation soapAction="urn:#NewOperation"/>
<wsdl:input>
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output>
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="NewService">
<wsdl:port name="NewPort" binding="tns:NewBinding">
<soap:address location="No Target Adress"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
請注意,輸出消息分為兩部分。
當使用SoapUI調用SOAP服務時,使用gSOAP框架實現的服務會返回不符合WSDL的響應:
這是SoapUI請求:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:new="http://new.webservice.namespace">
<soapenv:Header/>
<soapenv:Body>
<new:NewOperation>
<parameter>Hello</parameter>
</new:NewOperation>
</soapenv:Body>
</soapenv:Envelope>
這是gSOAP WS響應:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:new="http://new.webservice.namespace">
<soapenv:Header/>
<soapenv:Body>
<new:NewOperationResponse>
<result xsi:nil="true"/>
<param2>Hello World</param2>
</new:NewOperationResponse>
</soapenv:Body>
</soapenv:Envelope>
SoapUI抱怨以下錯誤:
line5: Element has xsi:nil attribute but is not nillable
題:
如何修復WSDL,以便消息部分可以為空?
看來您可能已設置SOAP_XML_NIL
標志? 不應設置此標志。 請參閱gsoap文檔,其中說明了SOAP_XML_NIL: output NULLs as xsi:nil
將空SOAP_XML_NIL: output NULLs as xsi:nil
。
