Issue
In my app I have an admin control panel that only allows admis to access. Here’s the code.
app.get('/acp', function (req, res) {
var user = firebase.auth().currentUser;
if (user) {
// Logged in
res.send('Hello world');
} else {
// Not logged in
res.redirect('/admin');
}
});
But when the user is not logged in, he’ll be redirected to admin login page, which also works fine.
The problem is I don’t know how I can redirect the user to admin control panel when he’s logged in.
app.get('/admin', function (req, res) {
res.sendFile(__dirname + '/public/admin.html');
});
app.post('/admin', function (req, res) {
const email = req.body.email;
const password = req.body.password;
firebase.auth().signInWithEmailAndPassword(email, password).catch(function(error) {
var errorCode = error.code;
var errorMessage = error.message;
});
res.redirect('/acp'); // the problem
});
Solution
signInWithEmailAndPassword returns a promise:
app.post('/admin', function (req, res, next) {
const email = req.body.email;
const password = req.body.password;
firebase.auth()
.signInWithEmailAndPassword(email, password)
.then(function(user) { res.redirect('/acp'); })
.catch(next);
});
