使用“时间戳”是一种廉价而神奇的方法。

this.router.navigate([], {
    relativeTo: this.route,
    queryParams: {
        ...this.route.snapshot.queryParams,
        // replace 't' with any others not to conflict with exsiting
        // '2^11' prevents reloading in about 2 seconds
        t: Date.now() >> 11, 
        skipLocationChange: true,
    },
});

通过使用一个虚拟组件和重新加载的路由解决了一个类似的场景，这实际上是一个重定向。这当然不能涵盖所有的用户场景，但只适用于我的场景。

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute } from '@angular/router';
import { Http } from '@angular/http';

@Component({
  selector: 'reload',
  template: `
    <h1>Reloading...</h1>
  `,
})
export class ReloadComponent implements OnInit{
  constructor(private router: Router, private route: ActivatedRoute) {
  }

  ngOnInit() {
    const url = this.route.snapshot.pathFromRoot.pop().url.map(u => u.path).join('/');
    this.router.navigateByUrl(url);
  }
}

路由使用通配符来捕获所有的url:

import { RouterModule } from '@angular/router';
import { NgModule } from '@angular/core';
import { LoginViewComponent } from './views/login/login.component';
import { HomeViewComponent } from './views/home/home.component';
import { ReloadComponent } from './views/reload/reload.component';

@NgModule({
  declarations: [ 
    LoginViewComponent, HomeViewComponent, ReloadComponent
  ],
  imports: [
    RouterModule.forRoot([
      { path: 'login', component: LoginViewComponent },
      { path: 'home', component: HomeViewComponent },
      { 
        path: 'reload',
        children: [{
          path: '**',
          component: ReloadComponent 
        }]
      },
      { path: '**', redirectTo: 'login'}
    ])
  ],
  exports: [
    RouterModule,
  ],
  providers: [],

})
export class AppRoutingModule {}

要使用这个，我们只需要在我们想要去的url中添加reload:

  this.router.navigateByUrl('reload/some/route/again/fresh', {skipLocationChange: true})

对我来说是硬编码

this.router.routeReuseStrategy.shouldReuseRoute = function() {
    return false;
    // or
    return true;
};

如果你通过Router Link改变路由，请遵循以下步骤:

  constructor(public routerNavigate: Router){

         this.router.routeReuseStrategy.shouldReuseRoute = function () {
            return false;
          };

          this.router.events.subscribe((evt) => {

            if (evt instanceof NavigationEnd) {

                this.router.navigated = false;
             }
          })
      }

订阅路由参数更改

    // parent param listener ie: "/:id"
    this.route.params.subscribe(params => {
        // do something on parent param change
        let parent_id = params['id']; // set slug
    });

    // child param listener ie: "/:id/:id"
    this.route.firstChild.params.subscribe(params => {
        // do something on child param change
        let child_id = params['id'];
    });

使用“时间戳”是一种廉价而神奇的方法。

this.router.navigate([], {
    relativeTo: this.route,
    queryParams: {
        ...this.route.snapshot.queryParams,
        // replace 't' with any others not to conflict with exsiting
        // '2^11' prevents reloading in about 2 seconds
        t: Date.now() >> 11, 
        skipLocationChange: true,
    },
});
