Node soap, consume password protected WSDL - node.js

Question

I'm trying to build a SOAP client with Node, I'm using "soap" package (https://www.npmjs.org/package/soap) trying to consume a user/password protected WSDL.
I can't find how to pass those credentials before creating the client by "soap.createClient", and of course, I can't retrieve the WSDL if I don't provide the right credentials.
I've tried doing:
soap.security.WSSecurity('user', 'pass');
and then calling "createClient" but to no avail.
Also, I've tried to do it with the node-soap-client, with this client I (apparently) can connect to the WSDL, but after that, I've no idea where to go (how to invoke methods).
What am I doing wrong?
Thanks for all your help!

Answer 1

Username and password credentials can be passed like this:
var soap = require('soap');
var url = 'your WSDL url';
var auth = "Basic " + new Buffer("your username" + ":" + "your password").toString("base64");
soap.createClient(url, { wsdl_headers: {Authorization: auth} }, function(err, client) {
});

If its password protected you also need to check the correct security mechanism. I spend a day trying to figure out that the service used NTLM security(it was a clients project and I only got username and password to access the wsdl). In that case, you would need to pass the correct wsdl_options object
var wsdl_options = {
ntlm: true,
username: "your username",
password: "your password",
domain: "domain",
workstation: "workstation"
}
soap.createClient(data.credentials[data.type], {
wsdl_options
},
function(err, client) {
console.log(client.describe());
});
Also, you would need to setSecurity on the client before using any service.

when I added the auth to the headers I still had a problem. After reading the code and a number of articles I found this to work.
// or use local wsdl if security required
let url = 'http://service.asmx?wsdl'
let wsdl = 'wsdl.wsdl';
let soap = require('soap');
let util = require('util')
soap.createClient(wsdl, function(err, client) {
//don't forget to double slash the string or else the base64 will be incorrect
client.setSecurity(new soap.BasicAuthSecurity('admin\\userName', 'password'));
client.MethodFromWSDL(args, function (err, result) {
console.log(util.inspect(result,{depth: null}))
});
});

This worked for me, the API required the auth parameters as
<UserDetails xmlns="http://url/">';
<userName>{$Username}</userName>
<password>{$Password}</password>
<program>{$program}</program>
</UserDetails>
After lots of trial and error - this ended working
const soapHeader = {
UserDetails: {
userName: process.env.userName,
password: process.env.password,
program: process.env.program
}
}
...
soap.createClient(path, function (err, client) {
if (err) {
console.log('Error creating SOAP client: ' + err);
}
client.addSoapHeader(soapHeader, "", "tns", process.env.URN);
client[process.env.FUNCTION](sargs, function (err, result, rawResponse, soapHeader, rawRequest) {
if (err) {
console.log('Error call SOAP function ' + process.env.FUNCTION + ': ', err);
}
else {
console.log(result);
}
...
