Question

我在mongo中有一个数据库，用于存储名为“SessionStore”的会话状态，其中包含一个名为“Sessions”的集合来存储会话状态。

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
}));

除非到达最后一行，否则会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);
           ^
TypeError: undefined is not a function

    at Module.runMain [as _onTimeout] (module.js:501:10)
    at Timer.listOnTimeout (timers.js:110:15)

我想我已经错过了部分设置，但我不确定是什么。任何人都可以提出建议。

最后的调用不正确 - 并且需要创建一个MongoStore实例

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

商店选项需要＆＃39; new＆＃39;在它之前。
