【问题描述】:
我正在尝试将变量传递给中间件,并在使用 facebook-passport 成功进行身份验证后可用。
// route for facebook authentication and login
router.get('/connect/facebook', rentalinfo, passport.authenticate('facebook', { scope : 'email' }));
// handle the callback after facebook has authenticated the user
router.get('/connect/facebook/callback', passport.authenticate('facebook', {
//successRedirect : '../../../protected',
failureRedirect : '/'
}),
function(req, res) {
// successful auth, user is set at req.user. redirect as necessary.
//Get the redirect location from the response
//console.log(req.body);
console.log(req.bookingarray);
res.redirect('/protected');
});
我的中间件:
//Rent item middleware - carries rental info through signup/login process
function rentalinfo(req, res, next){
//console.log('MIDDLEWARE VARIABLE: '+ bookingarray);
req.bookingarray = 'SOMETHING';
//return bookingarray;
//if (something(res)) redirect('http://google.com'); // no access to your site
next(); // go to routes
};
然后我尝试在我的 facebook 护照策略中访问它。
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 : ["emails", "displayName"],
// this allows us to pass in the req from our route (lets us check if a user is logged in or not)
passReqToCallback : true
},
// facebook will send back the token and profile
function(req, token, refreshToken, profile, done) {
console.log(req.bookingarray);
// asynchronous
process.nextTick(function() {
// check if the user is already logged in
if (!req.user) {
...
}
}
}));
但是它只是返回未定义。我试过了,我错过了什么?目的是保持用户在认证前后的状态。
【问题讨论】:
-
您的代码看起来不错。您确定那里没有任何错字或您分配给 bookingarray 的值已定义吗?没有其他代码会影响 req.bookingarray 吗?

已经更新了 facebook 路由 /connect/facebook/ 和 /connect/facebook/callback。我知道在没有变量的情况下正确授权。非常感谢您的帮助,我一直在撞墙
