PassportJS Profile Undefined Name

问题

I'm using PassportJS and passport-google-oauth in an ExpressJS web app.

var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
passport.use(new GoogleStrategy({
  clientID: GOOGLE_CLIENT_ID,
  clientSecret: GOOGLE_CLIENT_SECRET,
  callbackURL: CALLBACK
},
function(accessToken, refreshToken, profile, done) {
  console.log(profile.displayName);
  console.log(profile.name.familyName);
  console.log(profile.name.givenName);
  ...
}));

The problem is that profile.displayName, profile.name.familyName and profile.name.givenName are undefined. When I use the callback with Passport Facebook, no problem at all.

How to get the name of the user when using a Google account to login?

回答1:

When I checked it seems it has more parameters than what is in the official sample leading people to confusion including me..

rather than

function(accessToken, refreshToken, profile, done)

use

function(req, accessToken, refreshToken, profile, done)

you need to request for it, include 'https://www.googleapis.com/auth/userinfo.profile' in your scope.

passport.use(new GoogleStrategy({
  clientID: GOOGLE_CLIENT_ID,
  clientSecret: GOOGLE_CLIENT_SECRET,
  callbackURL: CALLBACK,
  scope: ['https://www.googleapis.com/auth/userinfo.profile','email', ...]
}
