Node js Error: Protocol "https:" not supported. Expected "http:"

When you want to request an https resource, you need to use https.get, not http.get.

https://nodejs.org/api/https.html

The reason for this error is that you are trying to call a HTTPS URI from a HTTP client. The ideal solution would have been for a generic module to figure out the URI protocol and take the decision to use HTTPS or HTTP internally.

The way I overcame this problem is by using the switching logic on my own. Below is some code which did the switching for me.

    var http = require('http');
    var https = require('https');
    // Setting http to be the default client to retrieve the URI.
    var url = new URL("https://www.google.com")
    var client = http; /* default  client */
    // You can use url.protocol as well 
    /*if (url.toString().indexOf("https") === 0){
                client = https;
    }*/
    /* Enhancement : using the  URL.protocol  parameter
     * the  URL  object ,  provides a  parameter url.protocol that gives you 
     * the protocol  value  ( determined  by the  protocol ID  before 
     * the ":" in the  url. 
     * This makes it easier to  determine the protocol, and to  support other  
     * protocols like ftp ,  file  etc) 
     */
   client = (url.protocol == "https:") ? https : client; 
    // Now the client is loaded with the correct Client to retrieve the URI.
    var req = client.get(url, function(res){
        // Do what you wanted to do with the response 'res'.
        console.log(res);
    });

As a side note to anyone looking for a solution from Google... make sure you are not using an http.Agent with an https request or you will get this error.
