我正在嘗試使用來自node.js的護照設置Facebook身份驗證。當我運行應用程序並轉到/ auth/facebook時,我會轉到Facebook頁面以授權Facebook返回我的電子郵件。但是,當我點擊確定後,我得到一個頁面(回調),說:「沒有電子郵件與此帳戶關聯!」根據代碼,這意味着profile.emails爲空。我錯過了什麼?Node.js Passport Facebook身份驗證沒有電子郵件返回
這些是當我啓動應用程序時顯示的警告。我不知道他們是否是問題。
express-session deprecated undefined resave option; provide resave option auth.js:44:37
express-session deprecated undefined saveUninitialized option; provide saveUninitialized option auth.js:44:37
以下是授權碼。我正在閱讀edx的介紹MEAN堆棧課程M101X。
function setupAuth(User, app) {
var passport = require('passport');
var FacebookStrategy = require('passport-facebook').Strategy;
// High level serialize/de-serialize configuration for passport
passport.serializeUser(function(user, done) {
done(null, user._id);
});
passport.deserializeUser(function(id, done) {
User.
findOne({ _id : id }).
exec(done);
});
// Facebook-specific
passport.use(new FacebookStrategy(
{
clientID: process.env.FACEBOOK_CLIENT_ID,
clientSecret: process.env.FACEBOOK_CLIENT_SECRET,
callbackURL: 'http://localhost:3000/auth/facebook/callback'
},
function(accessToken, refreshToken, profile, done) {
if (!profile.emails || !profile.emails.length) {
return done('No emails associated with this account!');
}
User.findOneAndUpdate(
{ 'data.oauth': profile.id },
{
$set: {
'profile.username': profile.emails[0].value,
'profile.picture': 'http://graph.facebook.com/' +
profile.id.toString() + '/picture?type=large'
}
},
{ 'new': true, upsert: true, runValidators: true },
function(error, user) {
done(error, user);
});
}));
// Express middlewares
app.use(require('express-session')({
secret: 'this is a secret'
}));
app.use(passport.initialize());
app.use(passport.session());
// Express routes for auth
app.get('/auth/facebook',
passport.authenticate('facebook', { scope: ['email'] }));
app.get('/auth/facebook/callback',
passport.authenticate('facebook', { failureRedirect: '/fail' }),
function(req, res) {
res.send('Welcome, ' + req.user.profile.username);
});
}
module.exports = setupAuth;
