Reset to default 3According to express docs of .redirect method:
res.redirect([status,] path)
Redirects to the URL derived from the specified path, with specified status, a positive integer that corresponds to an HTTP status code . If not specified, status defaults to “302 “Found”.
So you can't call it like that:
res.redirect('/',{Error:'block'});
Even if that method work, it'll just redirect to '/', which will trigger the app.get('/', function (req, res) {...} endpoint and show the initial login page, with error message hidden.
I believe, the best way it to change last line in app.post('/login', function (req, res) {...} to
res.render("login",{Error:"block"});
You can't make a redirection after an AJAX call if you're using AJAX. Use send instead
res.send({Error:'block'});
You can pass json with res.render method but to do with res.redirect you can use following.
- You can use
encodeURIComponentapp.get('/user', function(req, res) { var error = encodeURIComponent('error'); res.redirect('/?user=' + error); }); - Another way is using something in the session. Link to setup Sessions
req.session['error'] = "Error";
req.redirect('/'); - You can also use
