Get Phone IP address

[ariefbayu]

How do I get phone IP address in S40 WebApps? or if it's not possible, now do I get Nokia proxy IP address?

Hi,

There is no official way to get device IP address. If you want to get IP address of the proxy you can do it with following PHP script.

However the real question is, is there any use cases where IP address could be used?

<?php
 $ip = getenv("REMOTE_ADDR") ; 
 echo "IP " . $ip; 
 ?>

Hi,

How do I get phone IP address in S40 WebApps? or if it's not possible, now do I get Nokia proxy IP address?

There is the HTTP_X_Forwarded_For header added by the proxy. This is a pretty official approach with respect to how proxy servers work and the Nokia Web App proxy server is no different. I've set up a very simple phpinfo() page at http://hapnic.com/info.php that will list the variables passed to a remote server. If you create a simple web app to get this then it should display the device's IP address.

A remote script, more advanced than my really simple phpinfo(32), would be able to read the HTTP_X_Forwarded_For header variable and return it back to the client for display. And, if for some unknown reason this header disappears, then you can return the remote_addr header instead. But I am sure it won't disappear.

I've tested the Ajax retrieval of my info page with the following javascript where "info" is the ID of a div in my web app:

function getInfo() {
	var info = document.getElementById('info');
	var xmlhttp;
	xmlhttp = new XMLHttpRequest();
	xmlhttp.open("GET", "http://hapnic.com/info.php", false);
	xmlhttp.send();

	if (xmlhttp.status == 200) {
		info.innerHTML = xmlhttp.responseText;
	} else {
		verse.innerHTML = 'Communication error occurred';
	}
}

For clarification:
I need to get the IP (either proxy or device IP) from within my s40 web app. I need this IP to submit request to external API.

OK newer tough that possibility.

I summed this thread into a wiki page. It pretty much follows the principles that Stephen proposed in his post.

Hello and welcome to forum!

I afraid that you can't. If you want to have some kind of unique ID, best bet is to generate random string and store it to Web App preferences.

This is web apps, you can get client number but i you wanna get IP address client you can't again because your client using a proxy from nokia.

This is script for get IP client with PHP :

<?php
$ip = getenv("REMOTE_ADDR") ;
echo "IP " . $ip;
?>
