基于带有强制标头的WSDL创建WSO2代理

Question

在我场景中，有一个在WSO2-AS中运行的ESB服务"SolverDummyWS“，并希望在WSO2企业服务总线中为该服务生成一个代理。

因此，我手动为代理创建了wsdl，并添加了一些必需的标头字段。因此，只有代理的wsdl应该具有此标头。标头应该都是强制的和定义的als显式标头。

Proxy-WSDL看起来像这样：

<wsdl:definitions name="SolverDummyProxy"
targetNamespace="http://de.unistuttgart.iaas" xmlns:tns="http://de.unistuttgart.iaas"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">

<wsdl:types>
    <schema targetNamespace="http://de.unistuttgart.iaas"
        xmlns="http://www.w3.org/2001/XMLSchema">
        <element name="createGrid">
            <complexType>
                <sequence>
                    <element minOccurs="0" name="milliseconds" type="long" />
                </sequence>
            </complexType>
        </element>
        <element name="createGridResponse">
            <complexType>
                <sequence>
                    <element minOccurs="0" name="return" type="string" />
                </sequence>
            </complexType>
        </element>
        <element name="requestHeader">
            <complexType>
                <sequence>
                    <element minOccurs="1" name="simulationId" type="long" />
                    <element minOccurs="1" name="activityId" type="long" />
                    <element minOccurs="1" name="requiredPolicy" type="anyType" />
                    <element minOccurs="1" name="requiredPortType" type="string" />
                    <element minOccurs="1" name="requiredScope" type="anyURI" />
                </sequence>
            </complexType>
        </element>
    </schema>
</wsdl:types>

<wsdl:message name="createGridRequest">
    <wsdl:part name="body" element="tns:createGrid" />
    <wsdl:part name="reqHeader" element="tns:requestHeader" />
</wsdl:message>

<wsdl:message name="createGridResponse">
    <wsdl:part name="body" element="tns:createGridResponse" />
</wsdl:message>

<wsdl:portType name="SolverDummyProxyWSPortType">
    <wsdl:operation name="createGrid">
        <wsdl:input message="tns:createGridRequest" />
        <wsdl:output message="tns:createGridResponse" />
    </wsdl:operation>
</wsdl:portType>

<wsdl:binding name="SolverDummyProxyWSSoap11Binding" type="tns:SolverDummyProxyWSPortType">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" />
    <wsdl:operation name="createGrid">
        <wsdl:input>
            <soap:body parts="body" use="literal" />
            <soap:header message="tns:createGridRequest" part="reqHeader"
                use="literal" />
        </wsdl:input>
        <wsdl:output>
            <soap:body parts="body" use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>

<wsdl:binding name="SolverDummyProxyWSSoap12Binding" type="tns:SolverDummyProxyWSPortType">
    <soap12:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" />
    <wsdl:operation name="createGrid">
        <wsdl:input>
            <soap12:body parts="body" use="literal" />
            <soap12:header message="tns:createGridRequest" part="reqHeader"
                use="literal" />
        </wsdl:input>
        <wsdl:output>
            <soap12:body parts="body" use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>

<wsdl:service name="SolverDummyProxyWS">
    <wsdl:port name="SolverDummyProxyWSSoap11Endpoint" binding="tns:SolverDummyProxyWSSoap11Binding">
        <soap:address location="http://localhost:8280/services/SolverDummyProxyWS.SolverDummyProxyWSSoap11Endpoint" />
    </wsdl:port>
    <wsdl:port name="SolverDummyProxyWSSoap12Endpoint" binding="tns:SolverDummyProxyWSSoap12Binding">
        <soap12:address location="http://localhost:8280/services/SolverDummyProxyWS.SolverDummyProxyWSSoap12Endpoint" />
    </wsdl:port>
</wsdl:service>
</wsdl:definitions>

因此，我使用WSO2-ESB Webinterface创建了一个代理。如果我看一下创建的代理的实际WSDL，我会看到WSO2 ESB做了一些更改：-添加HTTP Binding -从createGridRequest消息中删除header-part - message soap:input in Binding(有两个header定义，并且body部分被删除)

WSDL-由WSO2修改-ESB

这段代码没有强制标头，所以我最初创建初始标头的目的被wso2-esb搞砸了。

谁能告诉我如何向代理服务添加强制标头(如果我的初始wsdl文件有错误，就会出现这种情况)？

如果我的初始wsdl文件是ok的，我如何强制wso2-esb使用这个文件，而不修改它？！？

最后一个问题，有没有其他方法可以为代理的请求创建强制标头？

感谢您的回答！

真的

尝试将此参数设置为您的代理服务，以按原样显示wsdl。应该使用中介器在代理服务级别处理soap标头。
