Question

I had a good idea, which kind of revolves around ips from the server the user is on.

Im very new to making a google chrome extension, but i am good at the programming languages that requires to build one .

Question: Can I get a IP from a server that the user is on? and if so how would you do this?

I was thinking just AJAX the url to my own server which then pings the server which would get the ip and returns that/stores it some where.

Answer 1

You can get current URL of tab\web Pageuser is currently browsing using chrome.tabs API

Demonstration

chrome.tabs.query({
    "currentWindow": true, //Filters tabs in current window
    "status": "complete", //The Page is completely loaded
    "active": true // The tab or web page is browsed at this state,
    "windowType": "normal" // Filters normal web pages, eliminates g-talk notifications etc
}, function (tabs) { //It returns an array
    for (tab in tabs) {
        _url_i_need = tabs[tab].url;
        //Do AJAX Stuff here 
    }
});

Ensure you declare tabs permission in your manifest as shown here

{
  "name": "My extension",
  ...
  "permissions": [
    "tabs"
  ],
  ...
}
