我正在寻找在我的AppComponent中检测路由变化。
然后,我将检查全局用户令牌,以查看用户是否已登录,以便在用户未登录时重定向该用户。

路由器3.0.0-beta。2应该是
this.router.events.subscribe(path => {
console.log('path = ', path);
});
其他回答
在组件中,你可能想尝试这样做:
import {NavigationEnd, NavigationStart, Router} from '@angular/router';
constructor(private router: Router) {
router.events.subscribe(
(event) => {
if (event instanceof NavigationStart)
// start loading pages
if (event instanceof NavigationEnd) {
// end of loading paegs
}
});
}
Angular 7,如果你想订阅路由器
import { Router, NavigationEnd } from '@angular/router';
import { filter } from 'rxjs/operators';
constructor(
private router: Router
) {
router.events.pipe(
filter(event => event instanceof NavigationEnd)
).subscribe((event: NavigationEnd) => {
console.log(event.url);
});
}
在Angular 2中,你可以订阅(Rx事件)一个Router实例。 你可以这样做
class MyClass {
constructor(private router: Router) {
router.subscribe((val) => /*whatever*/)
}
}
编辑(从rc.1开始)
class MyClass {
constructor(private router: Router) {
router.changes.subscribe((val) => /*whatever*/)
}
}
编辑2(从2.0.0开始)
请参见:路由器。活动文档
class MyClass {
constructor(private router: Router) {
router.events.subscribe((val) => {
// see also
console.log(val instanceof NavigationEnd)
});
}
}
以以下方式捕获路由更改事件…
import { Component, OnInit, Output, ViewChild } from "@angular/core";
import { Router, NavigationStart, NavigationEnd, Event as NavigationEvent } from '@angular/router';
@Component({
selector: "my-app",
templateUrl: "app/app.component.html",
styleUrls: ["app/app.component.css"]
})
export class AppComponent {
constructor(private cacheComponentObj: CacheComponent,
private router: Router) {
/* Route event types
NavigationEnd
NavigationCancel
NavigationError
RoutesRecognized
*/
router.events.forEach((event: NavigationEvent) => {
//Before Navigation
if (event instanceof NavigationStart) {
switch (event.url) {
case "/app/home":
{
//Do Work
break;
}
case "/app/About":
{
//Do Work
break;
}
}
}
//After Navigation
if (event instanceof NavigationEnd) {
switch (event.url) {
case "/app/home":
{
//Do Work
break;
}
case "/app/About":
{
//Do Work
break;
}
}
}
});
}
}
角8。检查当前路由是否为基路由。
baseroute: boolean;
constructor(
private router: Router,
) {
router.events.subscribe((val: any) => {
if (val.url == "/") {
this.baseroute = true;
} else {
this.baseroute = false;
}
});
}
