Node.js integration with MS Exchange EWS
I am attempting to use Node.js to call the SOAP Exchange EWS services. I have created a simple http client like so:
var https = require('https');
var username = 'user';
var password = 'password';
var auth = 'NTLM ' + new Buffer(username + ":" + password).toString('base64');
var options = {
host : 'exchangehost',
port : 443,
method : 'post',
path : '/Exchange.asmx',
headers : { Authorization : auth }
};
var request = https.request(options, function(response) {
console.log('Status: ' + response.statusCode);
};
request.write('<soapenv:Envelope ...></soapenv:Envelope>');
request.end();
I receive a status code 401, I suspect because I am not doing the three steps involved for NTLM authentication (http://www.innovation.ch/personal/ronald/ntlm.html). Does anyone know of a Node.js module for communicating with Exchange EWS directly or for authenticating using NTLM, or am I going to need to implement that protocol for Node.js myself? Any assistance is greatly appreciated.
I have used node-ews successfully to communicate with EWS.
node-ews uses httpntlm internally for NTLM authentication.
Personally, I think node-ews is your best bet, since its pretty much already implemented everything you need to interact with EWS.
Have you tried the httpntlm module? https://github.com/SamDecrock/node-http-ntlm
Have you tried ews-javascript-api npm module, it has all the features you are looking at + very simple ntlm authentication using ews-javascript-api-auth module. NTLMv2 is also supported.
I added this as answer as it would provide complete answer to question title (integration). These are github links, question is little generic so samples provided at github readme should work.
