Angular Router.navigate 到带有 queryParams 的子路由

Angular Router.navigate to child route with queryParams

无法通过 Angular.Router.navigate

使用 queryParams 导航到子路由

А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 } 
    ] 
}

当我尝试导航至 'desktop/search?q=folder' 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正常查询参数的子路由,如

.../desktop/search?q=folder

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

angular 中的路由器参数由“;”分隔不是 '&'。您必须使用参数定义路由:

{ 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 有一个参数及其对象:

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

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,您必须使用以下 URL:

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

2- 链接到带有参数的路由:

<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-读取路由参数:

// into component.ts

 constructor(private route: ActivatedRoute) {}

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

希望对你有所帮助。

对不起,一切正常。这是我在代码中的错字.. :) 所以,这里是使用 queryParams 的正确方法:

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

我不想使用 UrlParams,因为我会在这个页面上有很多参数,url 比如:

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

不会看美女。谢谢大家的帮助
