How can I use JWT in NodeJs for my app?

[Rui Costa]

Hi Community,

I am trying to connect my nodejs app to my jira instance, where I have my app installed.

I have saved all the tenant information on a json file "tenant.json", but when I try to generate a JWT to query my instance I am getting a "401 Unauthorized"

This is the code:

var jwt = require('atlassian-jwt');
var moment = require('moment');
var fetch = require('node-fetch');
var tenant = require('./tenant.json');


issue = '10001';const myreq = jwt.Request = jwt.fromMethodAndUrl('GET',  '/rest/api/2/issue/' + issue);

const now = moment().utc();

const tokenData = {
  "iss": tenant.clientKey,
  "iat": now.unix(),
  "exp": now.add(3, 'minutes').unix(),
  "qsh": jwt.createQueryStringHash(myreq)
};

const token = jwt.encode(tokenData, tenant.sharedSecret);

fetch(tenant.baseUrl + '/rest/api/2/issue/' + issue,
  {
   method: 'GET',
   headers: {
    'Authorization': 'JWT ' + token,
     'Accept': 'application/json'
   }
  }).then(response => {
     console.log(`Response: ${response.status} ${response.statusText}`);
   }).catch(err => console.error(err));

Can someone help?
