* Example for authenticationg against the ORCiD.org Public API with | |
* passport.js and retrieving the authenticated orcid. | |
* | |
* The main difficulty is that ORCiD.org will send the authenticated orcid | |
* in the accessToken request, which is normally not passed on to the | |
* passport.js-callback. Without the orcid, properly authenticating with | |
* ORCiD.org is impossible though. | |
* | |
* The trick is to pass on the `passReqToCallback`-option to the | |
* OAuth2Strategy, so that the callback will receive the complete content of | |
* the accessToken request. We can then use a callback function with the | |
* signature `(req, accessToken, refreshToken, params, profile, cb)`, where | |
* the parameter `params` will contain the JSON-parsed values of the | |
* accessToken answer. The orcid can then be accessed via `params.orcid`. | |
*/ | |
const passport = require('passport'); | |
const OAuth2Strategy = require('passport-oauth2').Strategy; | |
const orcid = new OAuth2Strategy( | |
{ // Configure your OAuth2Stragey as usual, but set `passReqToCallback` | |
…, | |
passReqToCallback : true | |
}, | |
(req, accessToken, refreshToken, params, profile, cb) => { | |
// You can now access the orcid and the name of the authenticated user | |
// in your passport callback and e.g. save it to your database for | |
// further use. | |
console.log(params.orcid); | |
console.log(params.name); | |
} | |
); | |
/* | |
* The remaining code would just be your usual passport.js configuration. | |
