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?有没有办法将子路由与正常的queryParams一起使用

.../desktop/search?q=folder

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

路由器参数中的角由';'分隔不是'&'。您必须使用以下参数定义路由:

{ path: 'hero/:id', component: HeroDetailComponent }

然后您可以使用此示例进行导航:

this.router.navigate(['/heroes', { id: heroId }]);

如您所见,router.navigate具有一个参数及其对象:

['/heroes', { id: heroId }]

看这个例子:

1-声明路线参数:

// 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>

<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']; 
    });
  }

希望对您有帮助。

对,一切正常。这是我在代码中的错字.. :) 因此,这是使用queryParams的正确方法:

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

我不想使用UrlParams,因为我将在此页面上有很多参数,并且网址如下:

.../foo/bar/foo1/bar1/foo2/bar2/.../foo-x/bar-x

看起来不会美。感谢所有人的帮助
