Angular Router.navigate通过queryParams导航到子路由

瓦伦丁·切尔尼什（Valentyn Chernysh）

无法通过Angular.Router.navigate的queryParams导航到子路线

已经尝试过：

this.router.navigateByUrl('/desktop/search?q=folder'));

this.router.navigate(['desktop', 'search'], { queryParams: {q: 'folder'} });

this.router.navigate(['desktop/search'], { queryParams: {q: 'folder'} });

我的路线：

{
    path: 'desktop',
    component: FavoritesPageComponent,
    children: [
      { path: 'desktop-admin', component: DesktopAdminComponent },
      { path: 'favorites', component: FavoritesBodyMainComponent },
      { path: 'sessions', component: SessionsComponent },
      { path: 'search', component: FavoritesBodySearchComponent },
      { path: 'shared_with_me', component: FavoritesBodySharedComponent },
      { path: 'recycle', component: FavoritesBodyRecycleComponent } 
    ] 
}

当我尝试导航到“桌面/搜索？q =文件夹”时，出现以下错误：

ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'desktop/search%3Bq%3D%25D0%25BF%25D0%25B0%25D0%25BF%25D0%25BA%25D0%25B0'

怎么了？有没有办法使用带有常规queryParams的子路由

.../desktop/search?q=folder

this.route.queryParams.subscribe(params => {
   console.log('params['q']: ', params['q']);
});

看这个例子：

1-声明路由参数：

// app.routing.ts    
export const routes: Routes = [
      { path: '', redirectTo: 'product-list', pathMatch: 'full' },
      { path: 'product-list', component: ProductList },
      { path: 'product-details/:id', component: ProductDetails }
    ];

要查看ID为10的产品的产品详细信息页面，必须使用以下URL：

localhost:4200/product-details/10 // it's not this -> /product-details?id:10

2-使用参数链接到路由：

<a [routerLink]="['/product-details', 10 or variable name]">
 title
</a>

要么

<a (click)="goToProductDetails($event,10)">
     title
</a>

// into component.ts
goToProductDetails(e,id) {
  e.preventDefault();
  this.router.navigate(['/product-details', id]);
}

3-读取路线参数：

// into component.ts

 constructor(private route: ActivatedRoute) {}

 ngOnInit() {
    this.route.params.subscribe(params => {
       this.id = +params['id']; 
    });
  }

我希望这可以帮助你。
