Для начала нужно удобнее организовать структуру
Пример как у меня организовано:
- /models/User.js
- /passports/facebook.js
- /passports/google.js
- /passport.js
- /routes.js
Содержимое passport.js
const User = require('./models/User')
const facebookStrategy = require('./passports/facebook')
const googleStrategy = require('./passports/google')
module.exports = function (passport) {
passport.serializeUser(function (user, done) {
return done(null, user.id)
})
passport.deserializeUser(async (id, done) => {
try {
const user = await User.findOne({ id })
done(null, user)
} catch (err) {
done(err)
}
})
passport.use(facebookStrategy())
passport.use(googleStrategy())
}
Содержимое facebookStrategy.js:
const assert = require('assert')
const FacebookStrategy = require('passport-facebook').Strategy
const User = require('../models/User')
assert(process.env.FACEBOOK_APP_ID)
assert(process.env.FACEBOOK_APP_SECRET)
assert(process.env.APP_URL)
module.exports = () => {
return new FacebookStrategy({
clientID: process.env.FACEBOOK_APP_ID,
clientSecret: process.env.FACEBOOK_APP_SECRET,
callbackURL: `${process.env.APP_URL}/auth/facebook/callback`
},
async (accessToken, refreshToken, profile, done) => {
try {
const user = await User.findOrCreate({ facebook_id: profile.id }, {
facebook_id: profile.id,
name: profile.displayName,
provider: 'facebook'
})
return done(null, user.toJSON())
} catch (err) {
return done(err)
}
})
}
routes.js
app.get('/auth/facebook', passport.authenticate('facebook'))
app.get('/auth/facebook/callback', passport.authenticate('facebook', { failureRedirect: '/login' }, (req, res) => {
const user = req.user;
const payload = {
id: user._id,
email: user.email,
};
jwt.sign(payload, secret, {expiresIn: 3600}, (err, token) => {
if (err) {
res.status(500).send({
error: 'Error signing token',
raw: err,
});
}
// Отдаем html
res.send(`
<script>
localStorage.setItem('token', '${`Bearer ${token}`}');
localtion.href = '/'
</script>
`);
});
})
в app.js
const passport = require('passport')
require('./passport')(passport)
app.use(passport.initialize())
