Verify ssl certificate in nodejs

Question

How can I verify SSL certificate on https of given domain by NodeJS?

I need to know if user open this like is it trusted or should add it as exception?

I think this code should raise error during unsigned or selfsigned certificate.

var https = require('https');

var options = {
  host: 'daarkoob.ir',
  port: 2222,
  path: '/',
  method: 'GET',
  rejectUnauthorized:true
};

var req = https.request(options, function(res) {
  console.log("statusCode: ", res.statusCode);
  console.log("headers: ", res.headers);
});
req.end();

req.on('error', function(e) {
  console.error(e);
});

https://daarkoob.ir:2222 is self signed certificated,so above code should raise error during surfing.but nothing happened.

Answer 1

From the documentation: rejectUnauthorized: If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Default true.

I guess that you need to specify a list of CA or the option is ignored.
