角度 6 ng-空闲

我有一个运行良好的 Angular 项目，我正在实施 NG-IDLE 和 KeepAlive，以便保持会话新鲜并在 API 会话过期之前注销用户。

我的问题是 ng-idle 也在登录页面上运行，这显然不是必需的，因为当它超时时，它会将用户带到登录页面。

因此，我在 app.component.ts 中启动并运行了 ng-idle 和 KeepAlive，但由于我使用延迟加载，因此我还有一个authentication.module.ts 和一个login.component.ts。

我的根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以防止空闲运行，并且在需要时调用idle.watch，但是我如何从登录或身份验证模块调用这些，或者我可以从根app.component检测。 TS？

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

由于给猫剥皮的方法总是不止一种，所以这是我自己解决这个问题的方法。我希望其他人将来会发现它有用。

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;
    }
}
