ReferenceError：會話未使用（'connect-mongo'）（會話）定義，

Question

我試圖添加connect-mongo以便在nodeJS重新啓動時保存會話。

每增加我的文檔： MongoStore = require('connect-mongo')(session),

，並在我的require('express-session')我加

store: new MongoStore({ 
    url: mongooseDB, 
    touchAfter: 24 * 3600 
}) 

和註釋掉app.use(passport.session());

我得到一個錯誤：不定義會話：引發ReferenceError它指向MongoStore = require('connect-mongo')(session),

我已經添加了我的app.js文件以供參考。我怎樣才能解決這個問題？

變量session當你調用 MongoStore = require('connect-mongo')(session)未初始化。

在初始化MongoStore之前添加session = require('express-session')。
