原本是使用
connect-mongo的，可能是express版本的升级报错了，改用connect-mongodb，但是使用后出现了如下的警告：
G:\nodejs\moviesite>grunt

moviesite started on port 3000下边的警告在session中添加两个属性值restart和saveUninitialized即可解决。

如：
app.use(session({
resave: false,//重新保存：强制会话保存即使是未修改的。(默认值ture)
saveUninitialized: true,//强制保存未初始化的会话到存储器
cookie: {maxAge:3600000},
secret:‘imooc‘,
store:new mongoStore({
url:dbUrl,
collection:‘sessions‘
})
}))剩下的警告应该是数据库不是安全连接，还未能解决，知道的朋友告诉一下
