How to parse Jason data from node.js console.log (response.body);

Question

I have been trying to get this right. My node.js code below returns to console log body of the response. The response has a access_token (JWT bearer). I need to have only the access_token out from the response and reuse the token for the next steps as parameter. Any suggestions appreciated.

var request = require('request');
var options = {
  'method': 'POST',
  'url': 'https://weburl-eu.eu.auth0.com/oauth/token',
  'headers': {
    'Content-Type': 'application/json'
    
  },
  body: JSON.stringify({
    "grant_type": "client_credentials",
    "audience": "urn:",
    "client_id": "id",
    "client_secret": "secret"
  })

};
request(options, function (error, response) {
  if (error) throw new Error(error);
  console.log(response.body);
});

Any Idea how to extract only value of the key "access_token" and use it again in my next from console.log(response.body); — Ro_Jo, Mar 12 '21 at 13:23

If you want to get a property from some stringified Json then you can do this, like tkausl suggested.

const obj = {
  auth: '1234',
  notAuth: 'a',
  someField: true
};

const stringified = JSON.stringify(obj);
console.log(stringified);

const auth = JSON.parse(stringified).auth
console.log(auth);

So I did as mentioned before. When I run the code it says undefined `request(options, function (error, response) { if (error) throw new Error(error); console.log (response.body); const stringBodytoJason = JSON.stringify(response.body) const token = JSON.parse(stringBodytoJason).access_token console.log(token); ` – Ro_Jo Mar 12 '21 at 14:03
I got it fixed. The issue. was (typeof response.body) was a string. So I had to do this to get only the token. ` const token = JSON.parse(response.body).access_token console.log(token); ` Thank you @ps_singh21 and @Stefan – Ro_Jo Mar 12 '21 at 14:30

request(options, function (error, response, body) {
   if (error) throw new Error(error);
   const stringBodytoJason = JSON.parse(body);
   const token = stringBodytoJason.access_token;
   console.log(token);
}
