我正在使用护照实施基本登录系统,但是当我使用正确的凭据登录时,我仍然收到此错误:
快车 500 TypeError:无法读取未定义的属性“passport”
但是,当我使用错误的凭据登录时,通过重定向回登录页面可以正常工作。救命?
app.js
//dependencies
var express = require('express');
var routes = require('./routes');
var http = require('http');
var path = require('path');
var mongoose = require('mongoose');
var passport = require('./auth');
var app = express();
server = require('http').createServer(app),
io = require('socket.io').listen(server);
// all environments
app.use(passport.initialize());
app.use(passport.session());
....
app.use(app.router);
app.use(require('less-middleware')({src: path.join(__dirname, 'public')}));
app.use(express.static(path.join(__dirname, 'public')));
......
//routes
app.get('/login', routes.login);
app.post('/login', passport.authenticate('local', {
failureRedirect: '/login',
successRedirect: '/user'
}));
app.get('/user', routes.user);
index.js
exports.login = function(req, res) {
res.render('login', {title: 'Log in'});
};
exports.user = function(req, res) {
if (req.session.passport.user === undefined) {
res.redirect('/login');
} else {
res.render('user', {title: 'Welcome!',
user: req.user
})
}
};
auth.js
var passport = require('passport'),
LocalStrategy = require('passport-local').Strategy;
passport.use(new LocalStrategy(
function(username, password, done) {
if (username === 'admin' && password === 'lynda') {
return done(null, {username: 'admin'});
}
return done(null, false);
}
));
passport.serializeUser(function(user, done) {
done(null, user.username);
});
passport.deserializeUser(function(username, done) {
done(null, {username: username});
});
module.exports = passport;
答案 0 :(得分:5)
您错过了会话声明,因此req.session未定义
app.use( express.cookieParser() );
app.use(express.session({ secret: 'my secret', cookie: { maxAge : 1200000 } }));
另外,你似乎在混淆要求:
var passport = require('./auth');
我会将其更改为:
var auth = require('./auth');
避免与护照库混淆
答案 1 :(得分:1)
你没有会话,所以你不能这样做(req.session.passport.user === undefined)......
您可能在登录后未设置会话
