Angular 6 个空闲

Question

我有一个运行良好的 Angular 项目，我正在实施 NG-IDLE 和 KeepAlive 以保持会话新鲜并在 API 会话到期之前注销用户.

我的问题是ng-idle也在登录页面运行，这显然不是必需的，因为当它超时时，它会把人带到登录页面。

所以我的 app.component.ts 中有 ng-idle 和 KeepAlive up 和运行但是因为我使用的是延迟加载，所以我还有一个 authentication.module.ts 和一个 login.component.ts.

我根app.component.ts中的代码如下：

import { Component } from '@angular/core';

import { Idle, DEFAULT_INTERRUPTSOURCES } from '@ng-idle/core';
import { Keepalive } from '@ng-idle/keepalive';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {

    idleState = 'Not started.';
    timedOut = false;
    lastPing?: Date = null;

    constructor(private idle: Idle, private keepalive: Keepalive) {

        // sets an idle timeout of 5 seconds, for testing purposes.
        idle.setIdle(5);

        // sets a timeout period of 5 seconds. after 10 seconds of inactivity, the user will be considered timed out.
        idle.setTimeout(5);

        // sets the default interrupts, in this case, things like clicks, scrolls, touches to the document
        idle.setInterrupts(DEFAULT_INTERRUPTSOURCES);

        idle.onIdleEnd.subscribe(() => this.idleState = 'No longer idle.');

        idle.onTimeout.subscribe(() => {
            this.idleState = 'Timed out!';
            this.timedOut = true;
        });

        idle.onIdleStart.subscribe(() => this.idleState = 'You\'ve gone idle!');
        idle.onTimeoutWarning.subscribe((countdown) => this.idleState = 'You will time out in ' + countdown + ' seconds!');

        // Sets the ping interval to 15 seconds
        keepalive.interval(15);

        keepalive.onPing.subscribe(() => this.lastPing = new Date());

        this.reset();
    }

    reset() {
        this.idle.watch();
        this.idleState = 'Started.';
        this.timedOut = false;
    }
}

我知道我需要调用 idle.unwatch 以防止在需要时空闲运行和 idle.watch，但是我如何从登录或身份验证中调用它们模块，或者我可以从根部检测 app.component.ts?

毫无疑问，您可以看出我是 Angular 的新手，所以如果这是一个菜鸟问题，我们深表歉意。

一种方法是为登录以外的路线设置一个主页。所有监视和取消监视逻辑都可以从 app.component.ts

移至此处

在app.routing.ts

const routes: Routes = [
    { path: 'login', component: LoginComponent },
    {
        path: '', component: HomeComponent,
        children: [
            // add auth requiring routes here
        ]
    }
];

在home.component.ts

export class HomeComponent implements OnDestroy {
    constructor() {
        // start watching here
    }  

    ngOnDestroy() {
        // unwatch here
    }
}

在home.component.html

<router-outlet></router-outlet>

因为剥猫皮的方法总是不止一种，这里是我自己解决这个问题的方法。我希望以后有人会觉得它有用。

import { Component } from '@angular/core';

import { Location } from '@angular/common';
import { Router } from '@angular/router';

import { Idle, DEFAULT_INTERRUPTSOURCES } from '@ng-idle/core';
import { Keepalive } from '@ng-idle/keepalive';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {

    currentPath: String;

    idleState = 'Not started.';
    timedOut = false;
    lastPing?: Date = null;

    constructor(private idle: Idle, private keepalive: Keepalive, location: Location, router: Router) {

        // sets an idle timeout of 5 seconds, for testing purposes.
        idle.setIdle(5);

        // sets a timeout period of 5 seconds. after 10 seconds of inactivity, the user will be considered timed out.
        idle.setTimeout(5);

        // sets the default interrupts, in this case, things like clicks, scrolls, touches to the document
        idle.setInterrupts(DEFAULT_INTERRUPTSOURCES);

        idle.onIdleEnd.subscribe(() => this.idleState = 'No longer idle.');

        idle.onTimeout.subscribe(() => {
            this.idleState = 'Timed out!';
            this.timedOut = true;
        });

        idle.onIdleStart.subscribe(() => this.idleState = 'You\'ve gone idle!');
        idle.onTimeoutWarning.subscribe((countdown) => this.idleState = 'You will time out in ' + countdown + ' seconds!');

        // Sets the ping interval to 15 seconds
        keepalive.interval(15);

        keepalive.onPing.subscribe(() => this.lastPing = new Date());

        // Lets check the path everytime the route changes, stop or start the idle check as appropriate.
        router.events.subscribe((val) => {

            this.currentPath = location.path();
            if(this.currentPath.search(/authentication\/login/gi) == -1)
                idle.watch();
            else
                idle.stop();

        });
    }

    reset() {
        this.idle.watch();
        this.idleState = 'Started.';
        this.timedOut = false;
    }
}

来自 user2191410 的好答案，当您分开所有路线时，停车非常简单。非常感谢，这是我的指南。

我有这个：

export class InitComponent implements OnInit {

  start watch()

}

ngOnDestroy() {
    // unwatch here
    this.idle.stop();
  }

在我的路由中：

{ path: 'dashboard',
      component: InitComponent,
      canActivate: [ AuthGuard ],
      children: [
          { path: '', component: DashboardComponent }
          All my pages are here...
           ]

}

登录组件是从InitComponent出来的，像这样：

const routes: Routes = [
    
  { path: 'login', component: LoginComponent },
  { path: 'lock', component: LockComponent },
  { path: 'recover', component: RecoverComponent }

];

AppComponent 有第一个 router-outlet

<router-outlet></router-outlet>

最后我的 InitComponents 有了第二个 router-outlet

<router-outlet></router-outlet>

您可以在启动ng-idle

之前先检查用户是否登录

  this.currentUser = this.authenticationService.currentUserValue;

  if (this.currentUser) {
    this.ifIsLogged = true ;

    // sets an idle timeout of 5 seconds, for testing purposes.
    idle.setIdle(3000000);
    // sets a timeout period of 5 seconds. after 20 seconds of inactivity, the user will be considered timed out.
    idle.setTimeout(2000000);
    // sets the default interrupts, in this case, things like clicks, scrolls, touches to the document
    idle.setInterrupts(DEFAULT_INTERRUPTSOURCES);

    idle.onIdleEnd.subscribe(() => {
      this.idleState = 'No longer idle.' ;
      alert('No longer idle. ') ;
    });

    idle.onTimeout.subscribe(() => {
      this.idleState = 'Timed out!';
      this.timedOut = true;
      this.logout() ;
    });
    
    idle.onIdleStart.subscribe(() => {
      this.idleState = 'You\'ve gone idle!' ;
    });

    idle.onTimeoutWarning.subscribe((countdown) => {
      this.idleState = 'You will time out in ' + countdown + ' seconds!' ;
    });

    // sets the ping interval to 15 seconds
    keepalive.interval(15);
    keepalive.onPing.subscribe(() => this.lastPing = new Date());
    this.reset();

  }
