使用javascript获取IP地址

Question

I just want to ask, is there a way on how to get ip addresses using javascript only? been searching for quite a while now and most of the results were I need to use api(s). I have used this webrtc and it works great but it's not working on IE, API is great, I've tested some and that works great in different browsers.

but I need to get the code itself from api, or is it possible to get/extract the code from api itself and make a specified file for the source so I won't rely on source from the internet?

I need the RAW file from api, because if ever the src of the api went down, my site will be affected too, so I want it to get and create a external source and include it on my site.

Answer 1

Try following solution :-

First option :-

$(document).ready(function () {
    $.getJSON("http://jsonip.com/?callback=?", function (data) {
        console.log(data);
        alert(data.ip);
    });
});

Second option :-

$.get("http://ipinfo.io", function(response) {
    alert(response.ip);
}, "jsonp");

It may help you.

I could be wrong, but I think you can only detect the IP serverside, so you'll have to do some kind of a get/post request.

The other answer shows a possible implementation of this.

Answer 3

You need to create script at backend of your site, that will be return IP, and execute it via ajax.

Or on the stage of generating page (at backend), you can detect IP, and put it to cookie, than read cookie from JS:

function getCookie(name) {
  var matches = document.cookie.match(new RegExp(
    "(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
  ));
  return matches ? decodeURIComponent(matches[1]) : undefined;
}

If you want source data you can get it from MaxMind: http://dev.maxmind.com/geoip/ There is a free and a paid version. Most of the IP info providers uses that library.

If you only need the IP, you can create a script of your own. Just create a backend script something like with PHP and request it from JS. Example: http://php.about.com/od/learnphp/qt/record_user_ip.htm
