SOAP request for child tags_问答_开发者_运维开发者技术经验分享

I have to make a SOAP request and its format is like this:

<parentname>test</parentname>    
<address>16, texas</address>    
<childrennames>
     <child>c1</child>
     <child>c2</child>
     <child>c3</child>     
</childrennames>    
<email>parent@gmail.com</email>

How to send request for childrennames tag?开发者_运维问答

One of the easiest approach, would be to have your entire SOAP request in a StringBuilder with some unique keys in place of actual values. Replace your keys by actual values at Runtime using StringBuilder#replaceAll(..) and then post this String to the server as StringEntity by setting the content-type for the entity as XML. For e.g: You can create a template as:

"<parentname>@parentName@</parentname>"

and then replace @parentName@ by the actual value at runtime.

You can use tools such as SOAPUI to generate the entire SOAP request XML. Hope you get a picture.

[EDIT : adding example for illustration] Supposing you have to create this SOAP request:

<soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:bok="http://www.example.org/bok/">
   <soapenv:Header/>
   <soapenv:Body>
      <bok:Name>
         <name>Foucault's Pendulum</name>
      </bok:Name>
   </soapenv:Body>
</soapenv:Envelope>

What I suggested was creating a String template and then replacing values in the template at run time:

// your SOAP request template
StringBuilder SOAP_REQUEST = 
new StringBuilder("<soapenv:Envelope 
xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' 
xmlns:bok='http://www.example.org/bok/'>
   <soapenv:Header/>
   <soapenv:Body>
      <bok:Name>
         <name>@name@</name>
      </bok:Name>
   </soapenv:Body>
</soapenv:Envelope>");

// replacing keys with actual arguments at runtime
SOAP_REQUEST.toString().replace("@name",actualName);

I hope that makes sense.

For the Simple Soap Request :

 SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    request.addProperty("Celsius", "32");

    SoapSerializationEnvelope soapEnvelop = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    soapEnvelop.dotNet = true;
    soapEnvelop.setOutputSoapObject(request);
    AndroidHttpTransport aht = new AndroidHttpTransport(URL);   

    try {

        aht.call(SOAP_ACTION , soapEnvelop);

        SoapObject resultString = (SoapObject) soapEnvelop.getResponse();
        } catch (Exception e) {
        e.printStackTrace();
    }
