Connecting to a web service using SOAP - node.js

Question

I am currently working on a node based application trying to make a request to a SOAP based service. I am making use of the node-soap module to work through this.
https://github.com/vpulim/node-soap
Currently i have the following implementation
var soap = require('soap');
var url = 'http:/xxxx/xxxx/xxxx?WSDL';
var appKey = 'ABYRCEE';
var xml = {
appKey: appKey,
mac: 'xxxxxxxx'
}
soap.createClient(url, function(err, client){
//console.log('Client:', client);
client.getAllDocsisVideoInfo(xml, function(err, result){
if(err){
console.log(err);
}
});
});
For the service to respond, i have a sample request in xml format, as the following
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:doc="http://xxx.xxx.com">
<soapenv:Header/>
<soapenv:Body>
<doc:getAllDocsisVideoInfo>
<appKey>"appKey"</appKey>
<mac>xxxxxxx</mac>
</doc:getAllDocsisVideoInfo>
</soapenv:Body>
</soapenv:Envelope>
As you can see from the above that i have to pass in appKey and mac values and upon a successful request this will send back successful response in xml format with the appropriate response.
I am able to see client object return back with the appropriate functions, but upon calling the client.getAllDocsisVideoInfo(....), i seem to see the following error
S:Client: Cannot find dispatch method for {}getAllDocsisVideoInfo
I am not sure of the why? Is it because of the way i am passing in the xml object, how do i pass in the sample request?

Answer 1

Looking at the node-soap api:
https://www.npmjs.com/package/soap
It looks like you have to call the function in the following manner:
client.getAllDocsisVideoInfo(xml, function(err, result, raw, soapHeader){
})
If you want to call it like you had it in your code, then I think you need to use the following:
Copy and paste from the API...
client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
// result is a javascript object
})

Answer 2

So after spending hours on this and banging my head, i was able to get a successful response by overriding the namespace prefix, by removing the namespace prefix.
For example, the following object needed to be passed as
var xml = {
':appKey': appKey,
':mac': 'xxxxxxxx'
}
Instead
var xml = {
appKey: appKey,
mac: 'xxxxxxxx'
}
This piece of the node-soap documentation [https://github.com/vpulim/node-soap#overriding-the-namespace-prefix][1] helped in figuring out the issue.
