Question

我使用connect-mongo模块在express中存储来自mongodb的会话。像这样使用它：

app.use(express.session({
    'secret': config.APP_SECRET,
    'store': new MongoStore({
        'db': db
    })
}));

其中：

var MongoStore = require(config.MODULES_DIR + 'connect-mongo')(express);
var db = mongoose.connection; // already connected as i use in in callback

但是当使用会话时我会收到此错误：

TypeError: Object #<Object> has no method 'open'
    at MongoStore._open_database (/node_modules/connect-mongo/lib/connect-mongo.js:174:15)
    at MongoStore._get_collection (/node_modules/connect-mongo/lib/connect-mongo.js:169:14)

Answer 1

如果您想使用Mongoose连接，则需要使用恰当命名的mongoose_connection选项：

new MongoStore({
  mongoose_connection : db 
})

Answer 2

我总是发现使用MongoUri连接更容易。大多数数据库服务都会为您提供一个数据库服务。看起来应该是这样的：

var mongoUri = 'mongodb://username:password@foo.mongohq.com/port/db'

app.use(express.session({
    store   : new MongoStore({
        url  : mongoUri
    })
}))

如何在NodeJS中存储MongoDB中的会话？
