connect-mongo 不适用于共享 mongo 集群。我们在我们的应用程序中添加了“connect-mongo”：“^0.8.2”模块，添加了以下配置详细信息。

"mongoStore": {
        "url" : "user:password@server1:27400/zeta-sessions,server2:27400/zeta-sessions,server3:27400/zeta-sessions",
        "name" : "web-app",
        "secret": "secret",
        "cookie": {
            "path": "/",
            "httpOnly": true,
            "maxAge": 31556952000 // 1 year
        },
"options" : {
                        "server": { "poolsize": 5 }
                        ,"replset": {"rs_name": "zeta-po"}

        },
        "resave": true,
        "saveUninitialized": true,
        "store": null    // NB: this will be overlaid in our module
}

还 ，

// ./lib/mongo-session.js
'use strict';

var session = require('express-session'),
    MongoStore = require('connect-mongo')(session);

/** Creates a Mongo-backed session store.
 *
 * @param {Object} [config] Configuration options for express-session and connect-mongo
 * @returns {Object} Returns a session middleware which is backed by Mongo
 */
module.exports = function (config) {
    // add the 'store' property to our session configuration
    config.mongoStore.store = new MongoStore(config.mongoStore);

    // create the actual middleware
    return session(config.mongoStore);
};

执行服务时出现以下错误。

Possibly unhandled Error: Required MongoStore option `db` missing or is not a string.

也许有点晚了，但我也遇到了类似的问题，我可以通过将我的 IP 地址添加到 IP 访问列表中来解决它，如本期所述。在您的 MongoDB Atlas 用户中，转到 Security -> Network Access 并添加您的 IP 或将其设置为由任何 IP 访问。
