'undefined is not a function' app.use NHibernate 中的会话错误,mongo 存储

' undefined is not a function' Error on app.use session in NHibernate, mongo store

我在 mongo 中有一个数据库,用于存储名为 'SessionStore' 的会话状态,以及一个名为 'Sessions' 的集合,用于存储会话状态。

我正在使用表达式会话来管理会话。

设置会话的代码如下;

var session     = require('express-session');
var MongoStore  = require('connect-mongo')(session);
.
.
.
var sessionDb           = 'SessionStore';
var sessionCollection   = ['Sessions'];
var mongojs             = require('mongojs');
var ObjectId            = mongojs.ObjectId;
var dbSessions          = mongojs(sessionDb, sessionCollection);
.
.
.
app.use(session({
    secret: 'mysessionsecret',
    name: 'connectionEngine',
    store: MongoStore({db: dbSessions}),
    proxy: true,
    resave: true,
    saveUninitialized: true
}));

除了到达最后一行时失败并显示以下内容;

C:\Users\Paul\Documents\Visual Studio 2015\Projects\Connection-Engine\Connection-Engine\node_modules\connect-mongo\lib\c
onnect-mongo.js:126
      self.emit(newState);
           ^

    at Timer.listOnTimeout (timers.js:110:15)

我想我错过了部分设置,但我不确定是什么。任何人都可以提出一些建议。

最终调用不正确 - 需要创建 MongoStore 实例

app.use(session({
    secret: 'w3happyf3ww3band0fbr0th3r5',
    name: 'connectionEngine',
    store: new MongoStore({db: 'SessionStore', collection: 'Sessions'}),
    proxy: true,
    resave: true,
    saveUninitialized: true
}));

商店选项前面需要 'new'。
