Writing a Python Client to access a Web Service

[heshan]

Hi,
I have written a web service and have deployed it using Apache Axis2. What I want to do is to invoke this service using a python script. Can anyone point me in the direction of how to do this. I will be grateful If anyone can give me a web reference to a code sample.I can do this with java. To give you an idea of what kind of a thing I want to do , I am attaching my java client code below.

import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.ServiceClient;
import org.apache.axis2.client.Options;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.impl.builder.StAXOMBuilder;
import javax.xml.stream.XMLStreamException;
import java.io.ByteArrayInputStream;

public class myClient {
    private static EndpointReference targetEPR =
            new EndpointReference("http://localhost:8080/axis2/services/annotationScript/deduct");


    public static OMElement getPayload() throws XMLStreamException {
        String str1 = "<f><a>4</a></f>";
        String str2 =  "<deduct><var1>1.8</var1><var2>4.87594</var2></deduct>";
        String str3 =  "<add><var1>1.8</var1><var2>4.87594</var2></add>";
        StAXOMBuilder builder = new StAXOMBuilder(new ByteArrayInputStream (str2.getBytes()));
        return builder.getDocumentElement();
    }

    public static void main(String[] args) throws Exception {
        ServiceClient sender = new ServiceClient();
        Options op = new Options();
        op.setTo(targetEPR);
        sender.setOptions(op);
        OMElement response = sender.sendReceive(getPayload());
        System.out.println(response);
    }
}

Hi heshan,
I have implemented an application that hits on an ASP.NET XML web service. I cut the code fragment below out of my app and removed specific references. Maybe this will help. The SOAP.py module is the core piece of code.

[language=python]
import SOAP
import time

class ENotebook(object):
    def __init__(self):
        pass
    
    def SendToENotebook(self,):

        SERVICE_PROXY = "http://server/location/AppName.asmx"

        SERVICE_NAMESPACE = "http://server/WebServiceName/Data"

        SERVICE_SOAP_ACTION = "http://WebServiceName/Data/MethodToCall"

        YourInformation = "Your Message to the Web Service"
       
        #Make sure we are at the start of the buffer
        Info.PDF_Mail_container.seek(0)
        #Create the SOAP message
        soapMsg = '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">\n'
        soapMsg = soapMsg + '  <soap:Body>\n'
        soapMsg = soapMsg + '    <Inbox_Inbound xmlns="http://WebServiceName/Data">\n'
        soapMsg = soapMsg + '      <Information>' + YourInfomation + '</Information>\n'
        soapMsg = soapMsg + '    </Inbox_Inbound>\n'
        soapMsg = soapMsg + '  </soap:Body>\n'
        soapMsg = soapMsg + '</soap:Envelope>\n'


        server = SOAP.SOAPProxy(proxy=SERVICE_PROXY,namespace = SERVICE_NAMESPACE, soapaction=SERVICE_SOAP_ACTION)

        #Send the soap command, get back True or False


        #Send the SOAP message
        bResult = server.Inbox_Inbound(soapMsg)
            
        return bResult

Hi Martin,
Thanx for your reply. Can you point me to a web reference on how to use SOAPpy , with some sample python code.
