`passport.use(new GoogleStrategy({
clientID: config.google.clientID,

I have used Google authentication using Passport in NodeJS. What is the significance of done() callback here, and why do we give null as an argument? I haven`t got any proper explanation. At least I should know why I am using the same.

I successfully got the user details but the email field is null.After some time got to know that I need to fetch it from "https://api.github.com/user/emails".I used axios and also provided accesstoken as header but it is giving me "▼♥��A�#►���\�%♥+=y��5"V↔ubWevW�迧F�¶◄t��☻�%)H�ɢ�k��♥葩$,�7↓�H�↔?��^Z�k�r���:��x�▬♣▬NP������҇�C�v�C▼o.�pK~☺" instead of emails.
passport.use(new GitHubStrategy({
clientID: process.env.GITHUB_CLIENT_ID,
clientSecret: process.env.GITHUB_CLIENT_SECRET,
callbackURL: "/callbackurl"
},
function(accessToken, refreshToken, profile, done) {
User.findOrCreate({ githubId: profile.id }, function (err, user){ //I am using mongoose-findorcreate npm
axios.get('https://api.github.com/user/emails', {
headers: {
"Authorization": "Bearer "+ accessToken,
}
}).then((res)=>{
console.log(res.data);
})
return done(err, user);
});
}
));
It's because you have not specified scope inside your strategy so Inside your github Strategy , also include scope key:
scope: ["user:email"],
As:
`new GitHubStrategy({
clientID: process.env.GITHUB_CLIENT_ID,
clientSecret: process.env.GITHUB_CLIENT_SECRET,
callbackURL: "/callbackurl",
scope: ["user:email"]
}`
I am creating API for login with google & login with facebook
whenever I call API URL I got error :
"TypeError: OAuth2Strategy requires a verify callback"
I am using local server for testing ,
Here is my code to implement google-outh-strategy with node.js
clientID: "clientId",
clientSecret: "clientsecret",
callbackURL: "http://localhost:3001/",
passReqToCallback: true
},
function (request, accessToken, refreshToken, profile, done) {
console.log(refreshToken);
console.log(accessToken);
console.log(profile);
done(null, profile)
}
));
Here is my references Docs for it :

I am writing a code to add functionality of logging in with Google. I have written code but when a user log in with google, it only gives me id, name, fullname etc. It does not provide with user email address. Can any one help me to solve this? Following is my code
passport.use(new GoogleStrategy({
clientID: CLIENT_ID,
clientSecret: CLIENT_SECRET,
callbackURL: "http://localhost:8000/auth/google/notepad"
},
function(accessToken, refreshToken, profile, cb) {
console.log(profile);
User.findOrCreate({ googleId: profile.id }, function (err, user) {
return cb(err, user);
});
}
));
router.get('/auth/google', passport.authenticate('google',{scope: ['profile']}));
router.get('/auth/google/notepad',
passport.authenticate('google', { failureRedirect: '/' }),
async function(req, res) {
const token = await req.user.generateAuthToken();
res.cookie('authToken', token);
res.redirect('/')
});
You are missing the email scope. It’s a separate scope to their profile.
See the docs too if you want to know more: https://developers.google.com/identity/protocols/oauth2/openid-connect#scope-param
I'm using passport-oauth2 for Oauth2 and confused in the implementation of authorizationURL & TokenURL as there is not any information present about this in official documentation.
passport.use(new OAuth2Strategy({
authorizationURL: 'https://www.example.com/oauth2/authorize',
tokenURL: 'https://www.example.com/oauth2/token',
clientID: EXAMPLE_CLIENT_ID,
clientSecret: EXAMPLE_CLIENT_SECRET,
callbackURL: "http://localhost:3000/auth/example/callback"
},
function(accessToken, refreshToken, profile, cb) {
User.findOrCreate({ exampleId: profile.id }, function (err, user) {
return cb(err, user);
});
}
));
Unable to retrieve the user email on LinkedIn. I have used passport-LinkedIn and OAuth 2.0. I can interpolate the username and picture. This is the code that I have tried.
var LinkedIn = require('passport-linkedin-oauth2').Strategy;
module.exports = (passport, User) => {
passport.use( new LinkedIn({
clientID: '86ew637ipvirsa',
clientSecret: 'HoEMfqCBGL9SxsIt',
callbackURL: 'http://localhost:3000/auth/linkedin/callback'
}, (accesstoken, refreshToken, profile, done) => {
User.findOne({'linkedin.id': profile.id}, (err, x) => {
if (x) return done(null, x);
var user = {
displayName: profile.displayName,
image: profile._json.pictureUrl,
email: profile.emailAddress,
linkedin: {
id: profile.id
}
};
User.create(user);
User.create(user, (err, x) => done(null, x));
});
}));
};
the npm package being used by you is not properly documented. The author has not explicitly said how you can access the email field from the profile variable.
You can pass in the scope with strategy and get the email fields by logging the profile variable.
passport.use(new LinkedInStrategy({
clientID: LINKEDIN_KEY,
clientSecret: LINKEDIN_SECRET,
callbackURL: "http://127.0.0.1:3000/auth/linkedin/callback",
scope: ['r_emailaddress', 'r_basicprofile'], //pass the scope
state: true
}, function(accessToken, refreshToken, profile, done) {
// asynchronous verification, for effect...
process.nextTick(function () {
console.log(profile); //logging
return done(null, profile);
});
}));
You can also use another package . Here you can explicitly define the profile fields you want to access.
