Connect-mongo会话不被自动删除 [英] Connect-mongo sessions not being deleted automatically

问题描述

我有一个使用NodeJS，Express，MongoDB和connect-mongo的应用程序。

我的问题是，当MongoDB中的会话似乎没有被自动删除时过期，所以数据库大小增长直到磁盘已满。

connect-mongo的开发人员发表评论：

connect-mongo将要求MongoDB删除在当前日期之前已经有
过期的所有会话。

但这似乎不我的配置是：

  var express = require（'express'）; 
 var MongoStore = require（'connect-mongo'）; 
 
 var sessionStore = new MongoStore（{db：'myappsession'}）; 
 
 var app = express.createServer（）; 
 
 app.configure（function（）{
 app.set（'views'，__dirname +'/ views'）; 
 app.set（'view engine'，' ejs'）; 
 app.use（express.bodyParser（））; 
 app.use（express.methodOverride（））; 
 app.use（express.cookieParser（））; 
 app.use（express.session（{secret：myappsecret，store：sessionStore}））; 
 app.use（app.router）; 
 app.use（express.static（ __dirname +'/ public'））; 
}）; 
  

我目前正在运行以下版本：

• 节点： 0.7.0-pre


• connect-mongo： 0.1.7


• express： 2.5.2


• 连接：
  

解决方案

您尚未设置 clear_interval 为您的会话。connect-mongo默认值为-1（或从不）：

clear_interval 清除过期会话的时间间隔（可选，默认值： -1 < STRONG>）。

每小时删除过期会话的示例（3600s）：

  var sessionStore = new MongoStore（{
 db：'myappsession'，
 clear_interval：3600 
}）; 
  

您还应确保设置了一个 maxAge 你的会话实际到期（例如使用1天）：

  app.use（express.session（{
秘密：myappsecret，
 cookie：{maxAge：24 * 60 * 60 * 1000}，
 store：sessionStore 
}））; 
  

I have an application using NodeJS, Express, MongoDB and connect-mongo.

My issue is that sessions don’t seem to be automatically deleted from MongoDB when they expire, so the db size grows until the disk is full.

The developer of connect-mongo wrote a comment:

connect-mongo will ask MongoDB to remove all the sessions that have expired before the current date.

But this doesn’t seem to be happening in my case.

My configuration is:

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

var sessionStore = new MongoStore({db: 'myappsession'});

var app = express.createServer();

app.configure(function(){
    app.set('views', __dirname + '/views');
    app.set('view engine', 'ejs');
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.cookieParser());
    app.use(express.session({ secret: "myappsecret", store:sessionStore }));
    app.use(app.router);
    app.use(express.static(__dirname + '/public'));
});

And I’m currently running the following versions:

• node: 0.7.0-pre
• connect-mongo: 0.1.7
• express: 2.5.2
• connect: 1.8.5

解决方案

You haven't set a clear_interval for your sessions .. the connect-mongo default is -1 (or "never"):

clear_interval Interval in seconds to clear expired sessions (optional, default: -1). Values <= 0 disable expired session clearing.

Example of removing expired sessions every hour (3600s):

var sessionStore = new MongoStore({
     db: 'myappsession',
     clear_interval: 3600
});

You should also make sure you have set a maxAge on your sessions to they actually expire (eg using 1 day):

app.use(express.session({
    secret: "myappsecret",
    cookie: { maxAge: 24 * 60 * 60 * 1000 },
    store:sessionStore
}));
