我的session 設(shè)置

app.use(logger('dev'));
app.use(express.static(path.join(__dirname,?'public')));
app.use(bodyParser.urlencoded({extended:?true}));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({?extended:?false?}));
app.use(cookieParser());

app.set('trust?proxy',?1)?//?trust?first?proxy
app.use(session({
??secret:'wsy1',
??key:'wsy1',
??cookie:?{
????maxAge:?1000?*?60?*?60?*?24?*?7,?//?1?week?
????domain:'.wsy1.com'
??},
??store:?new?MongoDBStore({
????uri:dbUrl,
????collection:'session'
??}),
??saveUninitialized:true,
??resave:false
}))

我使用MVC 做不局 ?然后再登錄的時候 將用戶信息存入session

exports.login?=?function(req,res){
????var?_admin?=?req.body.admin
????Admin.findOne({uname:?_admin.uname},??(err,?adminInfo)=>?{
????????if?(err)?{
??????????console.log(err)
????????}

????????if(!adminInfo){????????????
????????????console.log('該用戶不存在');??
????????}

????????adminInfo.comparePassword(_admin.pwd,(err,isMatch)=>{
????????????if?(err)?{
??????????????return?console.log(err)
????????????}

????????????if(!isMatch){
????????????????return?console.log('密碼錯誤')
????????????}?
????????????req.session.adminInfo?=?adminInfo
????????????//console.log(req.session)
????????????//req.session.adminInfo?=??adminInfo?

???????????return?res.redirect('/backend');
????????})


????})
};

但是我在?

router.use((req,res,next)=>{
????var?url?=?req.originalUrl;
????_adminInfo?=?req.session.adminInfo

????console.log(_adminInfo)
????//?if?(url?!=?"/backend/signin"?&&?!req.session.adminInfo)?{
????//?????return?res.redirect('/backend/signin');
????//?}
????next();
});

打印的時候 返回

undefined
