Javascript 如何在Angular 2 Meteor中从服务器端检测并注销空闲用户？

我是角2流星的新手。我正在实施一个项目，在该项目中，当用户关闭窗口时，我必须注销该用户；同样，当他打开应用程序时，他应该会看到登录页面

我在网上搜索了一下，但没有找到任何关于Angular 2 Meteor的信息

我发现了这个，但我不知道如何在Angular 2中为注销用户使用它。在Angular 2 Meteor中，将此代码放在服务器端的何处以及如何注销用户

Meteor.users.find({ "status.online": true }).observe({
  added: function(id) {
  },
  removed: function(id) {
  }
});

---

有人能帮忙吗？

我在我的一个项目中实现了这一点，您可以使用mizzao/meteor用户状态包从angular 2 meteor的服务器端注销。这就是你必须要做的

步骤1）首先安装此软件包

第2步）安装此工具后，您的用户收集表将显示一些包含基本帐户信息的新条目。现在，json文件有了一些额外的键

步骤3）服务器端的用户状态代码

步骤4）在登录页面的客户端，只需输入以下代码

ngOnInit() { 
         if (Meteor.user()) { <-- make sure you use Meteor.user() only . if you use Meteor.userId then it can create some issue because it is stored on localhost but Meteor.user() everytime calls server for user data. choice is yours.
             this._router.navigate([//your routename]);
           }
        }

ngOnInit（）{
if（Meteor.user（））{
 {
    "_id": "uxuhCgmCg6wkK795a",
    "createdAt": {
        "$date": "2016-09-30T05:54:07.414Z"
    },
    "services": {
        "password": {
            "bcrypt": "$2a$10$AxCqCcNsZzdtHSxB9ap9t.KY9kjV2E/U0woF4SFPRBqUD8Bj0XpuO"
        },
        "resume": {
            "loginTokens": [{
                "when": {
                    "$date": "2017-01-09T05:50:17.784Z"
                },
                "hashedToken": "XHpxCKS/kUALKyXCANDBHrJXRV9LAsmCBOOWwmUhAaU="
            }]
        }
    },

    "emails": [{
        "address": "jhon@gmail.com",
        "verified": false
    }],

        "online": true,
        "lastLogin": {
            "date": {
                "$date": "2017-01-09T05:50:19.055Z"
            },
            "ipAddr": "127.0.0.1",

        },
        "idle": false
    },
    "resume": {
        "loginTokens": []
    }
}

           import { Meteor } from 'meteor/meteor';

           Meteor.startup(() => {
               // load initial Parties
               Meteor.users.find({
                   "status.online": true
               }).observe({
                   added: function(id: any) {
                       // id just came online
                       console.log("--------- New User Login ---------");
                       console.log("user " + id.username + " (" + id._id + ") is online now");

                   },
                   removed: function(id: any) {
                       // id just went offline
                       console.log("----------- User idle --------------");
                       console.log("user " + id.username + " (" + id._id + ") is gone offline");
                       // ** use this mongodb query to remove user who go offline from server side 
                       Meteor.users.update({_id: id._id }, {$set: {"services.resume.loginTokens": []} }, { multi: true });
                   }
               });
           });

ngOnInit() { 
         if (Meteor.user()) { <-- make sure you use Meteor.user() only . if you use Meteor.userId then it can create some issue because it is stored on localhost but Meteor.user() everytime calls server for user data. choice is yours.
             this._router.navigate([//your routename]);
           }
        }
