Node SOAP client to connect to InDesign Server - node.js

Question

I am trying to get node/express to send soap request to indesign server.
Posting the request from Soap.ui or Postman works fine. Loading the "soap" page in the browser errors.
I also tried the node client with a few sample scripts from the new and they work, so the install should be OK.
This is what I have so far:
router.get('/soap', function(req, res, next) {
var url = 'http://<server_ip>:8088/service?wsdl';
var args = { "IDSP:RunScriptParameters" :
{ 'scriptLanguage': 'javascript',
'scriptFile': 'C:/indesign_scripts/test.jsx'
}
};
soap.createClient(url, function(err, client){
client.Service.Service.RunScript(args, function(err, result) {
if (err) console.log(err);
console.log(result);
});
});
client.describe() returns:
{ Service:
{ Service:
{ RunScript: [Object],
BeginSession: [Object],
EndSession: [Object] } } }
I am trying to use RunScript object.
client.describe().Service.Service.RunScript:
{ input:
{ runScriptParameters:
{ scriptText: 'xsd:string',
scriptLanguage: 'xsd:string',
scriptFile: 'xsd:string',
'scriptArgs[]': [Object],
targetNSAlias: 'IDSP',
targetNamespace: 'http://ns.adobe.com/InDesign/soap/' } },
output:
{ errorNumber: 'xsd:int',
errorString: 'xsd:string',
scriptResult:
{ data: 'xsd:anyType',
targetNSAlias: 'IDSP',
targetNamespace: 'http://ns.adobe.com/InDesign/soap/' } } }
Console shows this error:
[Error: connect ECONNREFUSED 127.0.0.1:8088]
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 8088 }
Indesign Server wsdl could be viewed here:

I suspect this is something with args variable format.

Answer 1

You can fix this issue by adding line below
client.setEndpoint('http://<server_ip>:8088');

Answer 2

I tried to add "Access-Control-Allow-Origin" to my headers in my app file, as suggested by #Chirdeep Tomar, but I am still getting the same errors.
The workaround I came up with was to use http request or curl for ajax post.
The example with request:
var express = require('express');
var request = require('request');
var parser = require('xml2json');
var router = express.Router();
router.get('/ProductionBooks/:id', function(req, res) {
var myId = req.params.id;
var myBody = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap="http://ns.adobe.com/InDesign/soap/"><soapenv:Body>'
+'<soap:RunScript>'
+'<runScriptParameters>'
+'<scriptLanguage>javascript</scriptLanguage>'
+'<scriptFile>C:/indesign_scripts/test.jsx</scriptFile>'
+'</runScriptParameters>'
+'</soap:RunScript>'
+'</soapenv:Body>'
+'</soapenv:Envelope>';
request({
url: 'http://192.168.0.129:8088', //URL to hit
method: 'POST',
headers: {
'Content-Type': 'application/xml',
'Content-Length': Buffer.byteLength(myBody)
},
body: myBody
}, function(error, response, body){
if(error) {
console.log(error);
} else {
console.log(response.statusCode + '\n');
var objJSON = JSON.parse(parser.toJson(body));
console.log(objJSON['SOAP-ENV:Envelope']['SOAP-ENV:Body']['IDSP:RunScriptResponse'].errorNumber);
}
});
res.end();
});
Example with curl:
var curl = require("curl");
curl.post(url, soapBody, options, function(err, response, body) {
try {
console.log(response.body);
}
catch (err) {
console.log(err);
}
});
res.end();
});

using easy-soap-request:
const soapRequest = require('easy-soap-request');
const url = 'http://[YOUR SERVER ADDRESS]:[IDS PORT]/service?wsdl';
const sampleHeaders = {
'user-agent': 'sampleTest',
'Content-Type': 'text/xml;charset=UTF-8',
};
const xml = '<?xml version="1.0" encoding="UTF-8"?>'
+'<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:IDSP="http://ns.adobe.com/InDesign/soap/">'
+'<SOAP-ENV:Body><IDSP:RunScript><IDSP:runScriptParameters>'
+'<IDSP:scriptLanguage>javascript</IDSP:scriptLanguage>'
+'<IDSP:scriptFile>[PATH TO SCRIPTS]/Hello.jsx</IDSP:scriptFile>'
+'<IDSP:scriptArgs><IDSP:name>myArg</IDSP:name><IDSP:value>Test Value</IDSP:value></IDSP:scriptArgs>'
+'</IDSP:runScriptParameters></IDSP:RunScript>'
+'<IDSP:RunScriptResponse><errorNumber>0</errorNumber><scriptResult><data xsi:type="IDSP:List"><item><data xsi:type="xsd:string">1</data></item></data></scriptResult></IDSP:RunScriptResponse>'
+'</SOAP-ENV:Body></SOAP-ENV:Envelope>';
// usage of module
(async () => {
const { response } = await soapRequest({ url: url, headers: sampleHeaders, xml: xml, timeout: 1000 }); // Optional timeout parameter(milliseconds)
const { headers, body, statusCode } = response;
console.log(headers);
console.log(body);
console.log(statusCode);
})();
Sample script (hello.jsx):
var arg = app.scriptArgs.get("myArg");
var res = "Your input: " + arg;
res;
