How to return an XML with node-soap server?

I'm making a NodeJS web service that contains API REST and SOAP methods (Im using https://www.npmjs.com/package/soap) with Express. With API REST I don't have any problem but with SOAP I have an inconvenient, when I try to consume the SOAP method from a testing C# application I can see that the parameters are going fine, but in the response I have the next error in C# (Response is not correct XML code)

When I consume the method from a NodeJS client with node-soap too the response working fine.

Part of my NodeJS code:

const express = require('express');
const bodyParser = require('body-parser');
const soap = require('soap');
const fs = require('fs');

const xml = fs.readFileSync('src/templates/ws_soap.wsdl', 'utf8');

const app = express();

app.use(bodyParser.urlencoded({
  extended: false
}));

app.use(bodyParser.json());

const soap_service = {
  integrations: {
    pull: {
      getSnapshotGIGA: function(args) {
        return {
          res: "HOLA"
        };
      },
    }
  }
};

app.listen(port, ip, function() {

  soap.listen(app, '/integrations_service', soap_service, xml, function() {
    console.log('SOAP web service started on ' + ip + ':' + port);
  });

  console.log('API REST started on ' + ip + ':' + port);
});

My WSDL file is next (In response I have the type string because I wanted to see how it behaved, but I need to return an object XML):

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="integrations_service" targetNamespace="http://localhost:4205/integrations_service" xmlns="http://localhost:4205/integrations_service" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <wsdl:part name="Password" type="xs:string"/>
  </wsdl:message>

  </wsdl:message>
  <wsdl:portType name="pull_integrations">
    <wsdl:operation name="getSnapshotGIGA">
      <wsdl:input message="getSnapshotGIGARequest"/>
      <wsdl:output message="getSnapshotGIGAResponse"/>
    </wsdl:operation>
  </wsdl:portType>
  <wsdl:binding name="pull_integrations_binding" type="pull_integrations">
    <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="getSnapshotGIGA">
      <soap:operation soapAction="getSnapshotGIGA"/>
      <wsdl:input>
        <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="literal"/>
      </wsdl:input>
      <wsdl:output>
        <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="integrations">
    <wsdl:port binding="pull_integrations_binding" name="pull">
      <soap:address location="http://localhost:4205/integrations_service"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

In C# I have an console application and I have registered the SOAP service as a web referency.

enter image description here

The way I consume the SOAP method is (When I make a SOAP Service with C# I test methods from this way too because is the way clients working):

Console.WriteLine("Consume NodeJS SOAP service");
Thread.Sleep(500);
integrations_service.integrations integrations = new integrations_service.integrations();
integrations.Url = "http://localhost:4205/integrations_service?wsdl";
var some_response = integrations.getSnapshotGIGA("myuser", "123456");
Console.WriteLine("Press enter to out...");

I want to get the response in and XmlNode like in this example:

Console.WriteLine("Consume C# SOAP service");
Thread.Sleep(500);
serviceSOAP sSOAP = new serviceSOAP ();
sSOAP.Url = "http://my.domain.com.mx/";
XmlNode xmlNode = sSOAP .anyMethodSoap("yomero", "123456");
Console.WriteLine(XElement.Parse(xmlNode.OuterXml).ToString());
Thread.Sleep(500);

If you know how I can return the XML from NodeJS and get it correctly in C# or any idea, I would appreciate it. Reggards.

Solution

  • Answer to my question, the problem was the WSDL configuration. With this configuration I made this works with C# web reference. The principal problem, the style, I changed it from "rpc" to "document" and configure correctly the element for the response.
