即時嘗試讓連接閃光燈在我的express3應用程序工作。連接閃光中間件不工作
我成功安裝該軟件包:
$ npm install connect-flash
我把它:
var flash = require('connect-flash');
設置好的了中間件:
app.use(function(req, res, next) {
res.locals.message = req.flash();
next();
});
app.use(flash());
,並用它:
app.get('/admin', function(req, res) {
if(loggedIn === true) {
res.redirect('/admin/books');
}
else {
res.render('login', {message: req.flash('error') });
}
});
app.post('/admin', function(req, res) {
if((adminAccount.username === getCrypted(req.body.username)) &&
(adminAccount.password === getCrypted(req.body.password))) {
loggedIn = true;
res.redirect('/admin/books');
}
else {
req.flash('error', 'Woops, looks like that username and password are incorrect.');
res.redirect('/admin');
}
});
但是我得到:TypeError: Object #<IncomingMessage> has no method 'flash'
。我遵循其github頁面上的說明。我錯過了什麼?
