我正在玩 Node/Express 3.0。但我不确定如何让会话结束。特别是我不确定我在 routes/session.js 中的以下内容是否正确。
app.use(function(req, res, next) {
res.locals.session = req.session;
next();
});
以下是更多细节。
我在 app.js 中有这个
var express = require('express')
, routes = require('./routes')
, http = require('http')
, path = require('path')
;
var app = express();
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('testtest'));
app.use(express.session({
secret: 'testtest',
maxAge: 3600000
}));
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
});
...
require ('./routes/session')(app);
...
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
在 routes/session.js 中
module.exports = function(app) {
app.use(function(req, res, next) {
res.locals.session = req.session;
next();
});
app.get('/session/new', function(req, res) {
res.render('session/new', {title: "Log in"});
});
app.post('/session', function(req, res) {
if (users[req.body.username] &&
users[req.body.username].password === req.body.password) {
req.session.user = users[req.body.username];
res.redirect('/users');
} else {
res.redirect('/session/new')
}
});
app.del('/session', function(req, res, next) {
req.session.destroy();
res.redirect('/users');
});
};
我有这个想法。
- if (session.user) {
p
span Hello
span= session.user.name
span= session
span !
p
form(method="POST", action="/session")
input(type="hidden", name="_method", value="DELETE")
input(type="submit", value="Log out")
- } else {
p
a(href="/session/new") Login
span or
a(href="/users/new") Register
- }
但这不会拿起会话并给出错误。
