Angular同一路由刷新页面的方法

默认，当收到导航到当前URL的请求，Angular路由器会忽略，重复点击同一链接页面不会刷新。

在hero.ts添加

constructor(private heroService: HeroService, private router: Router) {
  this.router.routeReuseStrategy.shouldReuseRoute = function () {
    return false;
  };
}

新建一个CustomReuseStrategy.ts文件

import {ActivatedRouteSnapshot, DetachedRouteHandle, RouteReuseStrategy} from '@angular/router';

export class CustomReuseStrategy implements RouteReuseStrategy {

  shouldDetach(route: ActivatedRouteSnapshot): boolean {
    return false;
  }

  store(route: ActivatedRouteSnapshot, handle: DetachedRouteHandle | null): void {
  }

  shouldAttach(route: ActivatedRouteSnapshot): boolean {
    return false;
  }

  retrieve(route: ActivatedRouteSnapshot): DetachedRouteHandle | null {
    return null;
  }

  shouldReuseRoute(future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
    return false;
  }

}

使用自定义RouteReuseStrategy：
最后在在AppRoutingModule.ts路由配置页面添加

@NgModule({
  imports: [RouterModule.forRoot(routes, {onSameUrlNavigation: 'reload'})],
  exports: [RouterModule],
  providers: [
    {provide: RouteReuseStrategy, useClass: CustomReuseStrategy}
  ]
})
