How to get unencoded Query Parameter in Node.js

Question

I am doing Google Oath2 Implementation. For a particular authorization_code, I was constantly getting invalid_grant. I checked the value and found that the query string value was encoded.

Here is an example:

const parser = require('url');
url ='http://example.com/test?param=4%2F12'
const q = parser.parse(url, true).query
console.log(q)

My output here is

{ param: '4/12' }

I want my output to be

{ param: '4%2F12' }

as the correct auth code is a string with value 4%2F12. How do I implement this?. There may be many manual ways to do this. Anything that needs a minimalistic code effort would be appreciated. Thanks in advance!

Answer 1

Simple. Just encode again the param using encodeURIComponent.

Example:

console.log(encodeURIComponent("4/12")) // Output: 4%2F12
