passportjs + facebook +当前用户
有一些问题搞清楚如何通过我的Facebooklogin访问当前用户。 我正在使用passportJS，Node，express。 我认为我的“用户”没有保持login状态，但我无法检查。 我会上传我所拥有的，谢谢任何人对它的看法 – 真的很感激。
route.js
app.get('/auth/facebook', passport.authenticate('facebook', { scope : ['email', 'public_profile', 'user_friends'] })); // handle the callback after facebook has authenticated the user app.get('/auth/facebook/callback', passport.authenticate('facebook', { successRedirect : '/profile', failureRedirect : '/' })); // route for logging out app.get('/logout', function(req, res) { req.logout(); res.redirect('/'); }); }; function isLoggedIn(req, res, next) { // if user is authenticated in the session, carry on if (req.isAuthenticated()) return next(); // if they aren't redirect them to the home page res.redirect('/'); } passport.js
passport.use(new FacebookStrategy({ // pull in our app id and secret from our auth.js file clientID : configAuth.facebookAuth.clientID, clientSecret : configAuth.facebookAuth.clientSecret, callbackURL : configAuth.facebookAuth.callbackURL, // profileFields: ['id', 'name','picture.type(large)', 'emails', 'username', 'displayName', 'about', 'gender'] }, // facebook will send back the token and profile function(token, refreshToken, profile, done) { // asynchronous process.nextTick(function() { // find the user in the database based on their facebook id User.findOne({ 'facebook.id' : profile.id }, function(err, user) { // if there is an error, stop everything and return that // ie an error connecting to the database if (err) return done(err); // if the user is found, then log them in if (user) { return done(null, user); // user found, return that user } else { // if there is no user found with that facebook id, create them var newUser = new User(); // set all of the facebook information in our user model newUser.facebook.id = profile.id; // set the users facebook id newUser.facebook.token = token; // we will save the token that facebook provides to the user newUser.facebook.name = profile.name.givenName + ' ' + profile.name.familyName; // look at the passport user profile to see how names are returned newUser.facebook.email = profile.emails[0].value; // facebook can return multiple emails so we'll take the first console.log(profile); console.log(user); console.log('it is working'); // save our user to the database newUser.save(function(err) { if (err) throw err; // if successful, return the new user return done(null, newUser); }); } }); }); })); // end of FacebookStrategy };
server.js
require('./config/passport')(passport); // pass passport for configuration // // required for passport app.use(session({ secret: 'ilovescotchscotchyscotchscotch' })); // session secret app.use(passport.initialize()); app.use(passport.session()); // persistent login sessions app.use(flash()); // use connect-flash for flash messages stored in session
这是我的第一个stackoverflowpost，所以先进的道歉，如果我侮辱任何人的格式。
你的用户应该被序列化一些。 例如：
// set up cookie parser and session var cookieParser = require('cookie-parser'); var session = require('express-session'); app.use(cookieParser()); app.use(session({ secret: 'mysecret', resave: true, saveUninitialized: false })); // passport init app.use(passport.initialize()); app.use(passport.session()); // Lets user information be stored and retrieved from session passport.serializeUser(function(user, done) { done(null, user.facebook.id); }); passport.deserializeUser(function(id, done) { User.findById(id, function(err,user){ if(err) done(err); done(null,user); }); });
然后你可以通过req.user访问用户对象。 例如，testing路线可以是：
app.get('/user', function(req, res, next) { res.send(req.user); });
祝你好运！
你也可以用另一种方式做到这一点：
router.get('/auth/facebook', function(req, res, next) { passport.authenticate('facebook', { scope : ['email', 'public_profile', 'user_friends'] } , function(err, user, info) { if(err) return res.status(400).send(err); if(user._id){ req.logIn(user, function(err) { if (err) { return next(err); } //redirect where you want return res.redirect(""); }); } })(req, res, next); })
req.logIn是用户obj创build会话和维护所需的一个函数。 否则护照将永远无法保持会话的用户。
