Ignore invalid self-signed ssl certificate in node.js with https.request?

I'm working on a little app that logs into my local wireless router (Linksys) but I'm running into a problem with the router's self-signed ssl certificate.

I ran wget 192.168.1.1 and get:

ERROR: cannot verify 192.168.1.1's certificate, issued by `/C=US/ST=California/L=Irvine/O=Cisco-Linksys, LLC/OU=Division/CN=Linksys/[email protected]':
Self-signed certificate encountered.
ERROR: certificate common name `Linksys' doesn't match requested host name `192.168.1.1'.
To connect to 192.168.1.1 insecurely, use `--no-check-certificate'.

In node, the error being caught is:

{ [Error: socket hang up] code: 'ECONNRESET' }

My current sample code is:

var req = https.request({ 
    host: '192.168.1.1', 
    port: 443,
    path: '/',
    method: 'GET'

}, function(res){

    var body = [];
    res.on('data', function(data){
        body.push(data);
    });

    res.on('end', function(){
        console.log( body.join('') );
    });

});
req.end();

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

How can I go about getting node.js to do the equivalent of "--no-check-certificate"?

Cheap and insecure answer:

Add

process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0;

in code, before calling https.request()

A more secure way (the solution above makes the whole node process insecure) is answered in this question
