How to get parameter of SOAP operation

    Hi Peter,

     

    I had a quick look and say you have a WSDL with operation defined like:

     

    ...

    <message name="GetInvoiceRequestMessage">
    <part name="invoiceRef" element="inv:getInvoice"></part>
    </message>
    <message name="GetInvoiceResponseMessage">
    <part name="invoiceDocument" element="inv:InvoiceDocument"></part>
    </message>
    <portType name="InvoicePortType">
    <documentation>Get An Invoice Using It's Invoice Number
    </documentation>
    <operation name="getInvoice">
    <input name="GetInvoiceInput" message="tns:GetInvoiceRequestMessage"/>
    <output name="GetInvoiceOutput" message="tns:GetInvoiceResponseMessage"/>
    </operation>
    </portType>
    <binding name="InvoicePortBinding" type="tns:InvoicePortType">
    <soap:binding style="document"
    transport="http://schemas.xmlsoap.org/soap/http" />
    <operation name="getInvoice">
    <soap:operation
    soapAction="http://soapui.cookbook.samples/getInvoiceRequest/request" />
    <input name="GetInvoiceInput">
    <soap:body use="literal" />
    </input>
    <output name="GetInvoiceOutput">
    <soap:body use="literal" />
    </output>
    </operation>
    </binding>

    ...

     

    Then adding these lines of code to your code's while loop:

     

    while (i.hasNext()) {

     op = (WsdlOperation) i.next();

     System.out.println("Operation: " + op.getName());

     MessagePart[] messageParts = op.getDefaultRequestParts();

     System.out.println("Request Message Part Name: "+messageParts[0].getName());

     System.out.println("Request Message Part Type: "+messageParts[0].getPartType());

     System.out.println("Request Message Part Description: "+messageParts[0].getDescription());

    }

     

    Gives output:

     

    Operation: getInvoice

    Request Message Part Name: invoiceRef

    Request Message Part Type: CONTENT

    Request Message Part Description: invoiceRef of type [{http://soapui.cookbook.samples/schema/invoice}InvoiceRefType]

     

    Is this something like what you want?

     

    Note, if you actually wanted the request, this can be generated by adding the following lines:

     

    WsdlOperation operation = (WsdlOperation) iface.getOperationByName( "getInvoice" );

    WsdlRequest request = operation.addNewRequest( "getInvoice Request" );

    System.out.println("Request String Content: "+operation.createRequest( true ).toString());

     

    Gives:

     

    Request String Content: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inv="http://soapui.cookbook.samples/schema/invoice">

       <soapenv:Header/>

       <soapenv:Body>

          <inv:getInvoice>

             <inv:invoiceNo>?</inv:invoiceNo>

          </inv:getInvoice>

       </soapenv:Body>

     

    Hope this helps,

    Cheers,

    Rup

Also Peter, I am curious to know why you would like to generate this information for a WSDL? Is it part of some kind of documentation tool?

Thanks,

Rup

Hi,

 

thanks for your answers, this goes in the right direction.

 

I write a programm where the user gives a url to a wsdl, gets the parameter he has to set und makes the request. 

All dynamic at runtime.

 

I have another question. I want to make a call to a webservice and get the result. But I am not able to pass some arguments. How should I archive this?

 

 WsdlOperation op = iface.getOperationAt(1);
                String soapVersion = iface.getSoapVersion().toString();
                String opName = op.getName();

                System.out.println("OPERATION:"+opName);

                WsdlRequest req = op.getRequestAt(0);

                System.out.println("REQUEST :"+req.getName());

                System.out.println("The request content is ="+req.getRequestContent());

                System.out.println("The action is ="+req.getAction());

                req.setEndpoint("http://www.webservicex.com/globalweather.asmx?WSDL");

                String result="";

                WsdlSubmitContext wsdlSubmitContext = new WsdlSubmitContext(req);
                wsdlSubmitContext.setProperty("CountryName", "Germany");
                wsdlSubmitContext.setProperty("CityName", "Berlin");

                wsdlSubmitContext.put("CountryName", "Germany");
                wsdlSubmitContext.put("CityName", "Berlin");
                WsdlSubmit<?> submit = (WsdlSubmit<?>) req.submit(wsdlSubmitContext, false);


                Response response = submit.getResponse();

                result = response.getContentAsString();

                System.out.println("The result ="+result);

It seems the parameters are ignored. How can I add parameters to a call?

 

Best regards

    Hi,

     

    Interesting topic... OK, well, I was short of time and not sure if this is the neatest/proper solution, but I think I have the gist of what you want. 

     

    In simple terms, I used XMLSlurper to parse and update the request XML content directly. Hope you'll forgive the mixed scripting, switch to Groovy, so the solution is a mixture, but works and may help you:

     

    ....

    WsdlOperation operation = (WsdlOperation) iface.getOperationByName( "getInvoice" );

    WsdlRequest request = operation.addNewRequest( "getInvoice Request" );

     

    //Create the request and capture the XML content

    String requestXMLString = operation.createRequest( true ).toString()

     

    System.out.println("Request String Content: "+requestXMLString);

     

    //Use XMLSlurper to pass and update the invoiceNo=7 in my getInvoice operation

    def envelopeNode = new XmlSlurper().parseText(requestXMLString)

    envelopeNode.Body.getInvoice.invoiceNo=7

     

    //This is just to serialize the XML objects back to a request XML String

    XmlUtil xmlUtil = new XmlUtil()

    requestXMLString = xmlUtil.serialize(envelopeNode)

    println( "modified request: g"+requestXMLString)

     

    //Update the SoapUI request content with the new updated XML request content

    request.setRequestContent(requestXMLString)

     

    //Submit as you did

    WsdlSubmit submit = (WsdlSubmit) request.submit( new WsdlSubmitContext(), false );

    Response response = submit.getResponse();

    String content = response.getContentAsString();

    System.out.println( content );

     

    This gives output like:

    ...

    Request String Content: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inv="http://soapui.cookbook.samples/schema/invoice">

       <soapenv:Header/>

       <soapenv:Body>

          <inv:getInvoice>

             <inv:invoiceNo>?</inv:invoiceNo>

          </inv:getInvoice>

       </soapenv:Body>

    </soapenv:Envelope>

    modified request: g<?xml version="1.0" encoding="UTF-8"?>

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

       <soapenv:Header/>

       <soapenv:Body>

          <inv:getInvoice xmlns:inv="http://soapui.cookbook.samples/schema/invoice">

             <inv:invoiceNo>7</inv:invoiceNo>

          </inv:getInvoice>

       </soapenv:Body>

    </soapenv:Envelope>

    13:35:46,383 DEBUG [HttpClientSupport$SoapUIHttpClient] Connection can be kept alive indefinitely

          <InvoiceDocument xmlns="http://soapui.cookbook.samples/schema/invoice">

             <invoiceNo>7</invoiceNo>

             <company>Test Company</company>

             <amount>100.0</amount>

          </InvoiceDocument>

       </S:Body>

    </S:Envelope>

    13:36:18,498 DEBUG [SoapUIMultiThreadedHttpConnectionManager$SoapUIDefaultClientConnection] Connection closed

     

    (Note this service is just a stub that returns the invoiceNo from the request, plus hardcoded Test Company and 100)

     

    Is this what you need?

     

    Cheers,

    Rup

      Thanks,

       

      this is exactly what I needed. Now I can build the request on runtime.

      Thanks for your help.

       

      Best regards,

      Peter

        Hi Peter,

         

        Great, glad it workd for you, good luck with creating your request builder tool! :-)

         

        If you're happy with the solution, please can you mark the solution as accpeted so that others may take more note of it?

         

        Thanks,

        Rupert
