如果用户尝试导航到http://www.example.com/news.html（或任何其他非登录页面的html页面），如果用户未登录，我需要将他重定向到登录页面。
我尝试了下面的代码，但是一旦我进入if的真正代码块，res.render或res.redirect就完全没有了。如果我在console.log那里它正常工作。所以我猜res对象有问题。
app.use(function(req, res, next) {
if (req.session.user == undefined) {
// if user is not logged-in redirect back to login page //
res.render('es/login', {
title: 'Hello - Please Login To Your Account'
});
} else {
next();
}
});
如果我是console.log（res），我得到：

我正在使用的Express版本：“3.4.4”
编辑14/07/2015。我的问题仍然存在，我正在编写更多代码，看看是否有人可以帮助我...
我的主要app.js代码：
var express = require('express');
var http = require('http');
var app = express();
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/app/server/views');
app.set('view engine', 'jade');
app.locals.pretty = true;
// app.use(express.favicon());
// app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.cookieParser());
app.use(express.session({ secret: 'Whateverpass',cookie:{maxAge:30 * 24 * 60*60*1000}}));
app.use(express.methodOverride());
app.use(require('stylus').middleware({ src: __dirname + '/app/public' }));
app.use(express.static(__dirname + '/app/public'));
});
if ('development' == app.get('env')) {
}
app.configure('development', function(){
app.use(express.errorHandler());
});
require('./app/server/router')(app);
var httpserver = http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
我的router.js位于（'./app/server/router'）：
var locale = require（“locale”）; var supported = new locale.Locales（[“en”，“es”]）;
module.exports = function（app）{
app.use(locale(supported));
app.use(function(req, res, next) {
if (req.session.user == undefined) {
// if user is not logged-in redirect back to login page //
res.render('es/login', {
title: 'Hello - Please Login To Your Account'
});
} else {
next();
}
});
app.get('/', function(req, res){
[...]
});
app.post('/', function(req, res){
[...]
});
[...]
}
答案 0 :(得分：2)
尝试在return或res.render
res.redirect
app.use(function(req, res, next) {
if (req.session.user == undefined) {
return res.render('es/login', { title: 'Hello - Please Login To Your Account' });
}
else {
next();
}
});
答案 1 :(得分：0)
尝试编写返回语句，如下所示：
return (
res.render('es/login', {
title: 'Hello - Please Login To Your Account'
});
);
