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: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.
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.
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.
