Get IP address on Chrome App

I'm developing a Chrome app, and I need to get the external IP address.

I've tried loading external scripts, but I was getting errors even though I added the sources to 'content_security_policy' on the manifest.json file.

I gave up, and then I tried making an XMLHttpRequest request to an IP host/service website, but requests need to be async and I wasn't able to save the response to a variable even using setTimeout().

I was always getting undefined because the variable was clearly being set before the request was completed.

So can you please help me find a simple solution to get the IP?

This site http://jsonip.com/ outputs a JSON object like this: 

{"ip":"xxx.xxx.xxx.xxx","about":"/about","Pro!":"http://getjsonip.com"}

You can perform an asynchronous XMLHttpRequest to that site like this:

var xhr = new XMLHttpRequest(),
    IP_ADDRESS;

xhr.onreadystatechange = function() {
    if (xhr.readyState==4 && xhr.status==200) {
        IP_ADDRESS = JSON.parse(xhr.responseText).ip;
        console.log('IP ADDRESS: ' + IP_ADDRESS);
        // Log it or do something else so you'll know that the response has been received
    }
}

xhr.open('GET', 'http://jsonip.com/', true);
xhr.send();

After a while you'll see a log like this in the console:

IP ADDRESS: 12.34.567.89
