@ being converted into string when passing in the URL

Question

I am trying to post data to a URL through HTTP request, when I try to pass email then it converts @ into %252540.

Here is the URL:

window.open('https://secure.rspcdn.com/xprr/red/PID/3428/SID/rentown?email=amrinder@odz.com');

Please take a look at the given fiddle:

https://jsfiddle.net/amrindernoor/b8uvwr86/

How can I avoid this issue?

Your URL https://secure.rspcdn.com/xprr/red/PID/3428/SID/rentown?email=amrinder@odz.com has multiple internal redirects.

In each redirect, it encodes the already encoded email.

Here is the brief explanation on what exactly is causing the issue:

At first, @ is passed as it is.

During first redirection, it is encoded to %40 which is still valid.

Here after in each redirection, it gets encoded again resulting in %252540 as the final value.

Below is the screen shot that will give you a clear picture on this

ah! got it, but what's the solution now? as i don't have access of the server where the second redirection exists. – Amrinder Singh Dec 19 '16 at 10:17
There is no other solution other than contacting concerned person to grant you access so that encoding stuff can be fixed from root cause. – Samir Selia Dec 19 '16 at 11:26

Use encodeURIComponent for the email address parameter:

window.open('https://secure.rspcdn.com/xprr/red/PID/3428/SID/rentown?email=' + encodeURIComponent('amrinder@odz.com'))

The correct value for the email parameter (returned by encodeURIComponent) is ˙amrinder%40odz.com˙, which will be interpreted as amrinder@odz.com server-side.

After the change, that URL returns a 302 redirect to https://www.rsptrack.com/click.track?CID=287283&AFID=276422&SID=rentown&SID2=n&SID3=n&email=amrinder%40odz.com&zid=f197f1cfb16ae7d56748bca35ebe7658&tkp=3428&tku=4160&tks=86073803, which seems to contains the correct value for the email parameter.

You can use encodeURIComponent() function to get it done. This function encodes special characters. In addition, it encodes the following characters: , / ? : @ & = + $ #

window.open('https://secure.rspcdn.com/xprr/red/PID/3428/SID/rentown?email=' + encodeURIComponent('amrinder@odz.com'))

Note :

Use the decodeURIComponent() function to decode an encoded URI component.
