使用session_id从Mongo快速加载会话 [英] Express load Session from Mongo with session_id

问题描述

嘿，

我正在构建一个(半)REST API，其背面为Nodejs/Express，而正面为Phonegap/Cordova.对于后端，我使用 express 和 connect-mongo 和 猫鼬 如下:

I'm building a (semi) REST API with Nodejs/Express as back and Phonegap/Cordova as front. For backend i'm using express with connect-mongo and mongoose as following :

express.cookieParser(),
express.session({
    secret: nconf.get('session:salt'),
    store: new mongoStore({url: nconf.get('database').url})
}),

为了在节点上进行会话验证，我在我的 route.js 文件中创建了以下功能

for session validation on node i've create the following function inside my route.js file

var authenticate = function (req, res, next) {

if (req.session.user)
    next();
else
    res.error('access is not authentication');
}

不幸的是，PhoneGap和Cordova不支持现成的Cookie ，所以我使用了 localStorage 存储session_id并包装每个服务器调用，以将其聚集到url参数中.

Unfortunately PhoneGap and Cordova do not support cookies out of the box so i use localStorage to store session_id and wrap every server call to aggregate it to the url params.

是否有任何优雅的方法通过'session_id'参数从我的 authenticate 函数中的mongoDB中预加载会话，而无需为会话集合创建 Schema 并尝试用猫鼬查询吗?

Is there any elegant way to pre-load the session from mongoDB inside my authenticate function by the 'session_id' param without creating a Schema for the session collection and try querying it with mongoose?

干杯

推荐答案

使用 mongoStore 的 store.get 方法.尝试这样的事情:

Use the store.get method of your mongoStore. Try something like this:

var authenticate = function (req, res, next) {
  mongoStore.get(req.params.session_id, function (error, session) {
    if (error) {
      res.status(500).send(error);
      return;
    }
  }
  req.session = session;
  next();
}
