Answer 1

What exactly can't you do? Extract the data from the URL? Convert the Base64 data to JSON? Convert JSON to data?

If your problem is simply decoding the Base64 data, you can try the JavaScript function btoa() .

EDIT (from a suggestion of Sashisu Kumar):

You can also install the js-base64 package: npm install --save js-base64 , then:

import { Base64 } from 'js-base64';
console.log("sssdecrpt",Base64.decode(sd))

Answer 2

The string shown in the example above looks like a base-64 encoded string.

The base-64 encoded string can be decoded easily using Buffer.from() as shown below.

Working example of decoding base-64 data:

// File name: decode-demo.js

let input = "eyJzIjoiWlIybnJVcGxVLUlGNnFZcW03cWVmUmo4MVVnIiwidiI6MSwicCI6IntcInVcIjozMDEwMTMzMixcInZcIjoxLFwidXJsXCI6XCJodHRwczpcXFwvXFxcL3Rlc3QudmFuaGV1c2VuaW5kaWEuY29tXFxcL3Jlc2V0cGFzc3dvcmRcXFwvY29udGVudFxcXC9zZWN1cmVfa2V5XFxcL2U5MmUzOWRlMDEwZmQyMTQ0ODg3NTJlODZkZTQ2NmFhXFxcL2lkX2N1c3RvbWVyXFxcLzE2OTM1ODVcXFwvc2VjXFxcLzE1OTA4MjYwMDQuNDU4XFxcL290cFxcXC8yNTgyMDE_dXRtX3NvdXJjZT1QaWdlb25fZm9yZ2V0X3Bhc3N3b3JkJnV0bV9tZWRpdW09ZW1haWwmdXRtX2NhbXBhaWduPWZvcmdldF9wYXNzd29yZFwiLFwiaWRcIjpcIjIzZGZkNDNiOGY1ODRlMmJiYTdjMzcyNGM2ZDgxMTY4XCIsXCJ1cmxfaWRzXCI6W1wiYTk4ZmEwMDgxYTk3ZjY3MGRmNDc3ZTI4MDFlYThlMzIzN2Q4YmQwMlwiXX0ifQ"
let base64Data = Buffer.from(input, 'base64')
console.log("Decoded value: \n" + (base64Data.toString()))

Output:

> node decode-demo.js

Decoded value:

{
    "s": "ZR2nrUplU-IF6qYqm7qefRj81Ug",
    "v": 1,
    "p": {
            "u": 30101332,
            "v": 1,
            "url": "https://test.vanheusenindia.com/....",
            "id": "23dfd43b8f584e2bba7c3724c6d81168",
            "url_ids": ["a98fa0081a97f670df477e2801ea8e3237d8bd02"]
    }
}
