问题描述
我有一个运行良好的Angular项目，并且正在实施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，因为当超时时，它将把该人带到登录页面.
因此，我在app.component.ts中启动并运行了ng-idle和KeepAlive，但是由于我使用的是延迟加载，因此我还具有了authentication.module.ts和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来防止空闲运行和idle.watch何时需要，但是如何从登录或身份验证模块中调用它们，或者如何从根应用程序进行检测.component.ts?
毫无疑问，您可以说我是Angular的新手，如果这是一个菜鸟问题，我们深表歉意.
解决方案
由于总是有不止一种方式给猫剥皮，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;
}
}
I have an Angular Project which is working well and I'm implementing NG-IDLE and KeepAlive in order to keep the session fresh and to log a user out before the API session expires.
My issue is that the ng-idle is also operating on the login page, which is obviously not required, as when it does time out, it will take the person to the login page.
So I have the ng-idle and KeepAlive up and running in my app.component.ts but since I'm using lazy loading, I also have an authentication.module.ts and a login.component.ts.
The code in my root app.component.ts is as follows:
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;
}
}
I know I need to call idle.unwatch in order to prevent idle running and idle.watch when I need it to, but how can I either call these from the login or authentication module, or can I detect from the root app.component.ts?
As no doubt you can tell that I'm new to Angular, so apologies if this is a rookie question.
解决方案
Since there are always more than one way to skin a cat, here's my own solution to this issue. I hope someone else finds it useful in the future.
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;
}
}
