我使用angular 2进行路由,使用节点进行本地托管。
当我对我的路线使用'useAsDefault:true'时,导航栏链接不再有效,当我希望它转到http://localhost/
http://localhost/home(空白页) >我删除了导航栏正常工作的标志,我可以转到/ home路线但是我转到空白页
任何人都可以了解默认标志无法正常工作的原因吗?
App.Component.ts
@RouteConfig([
{ path: '/home', name: 'Home', component: HomeComponent /*, useAsDefault : true */},
{ path: '/articles', name: 'Posts', component: PostsComponent },
{ path: '/detail/:id', name: 'PostDetail', component: PostDetailComponent },
{ path: '/login', name: 'Login', component: LoginComponent },
])
App.Component.html
<ul class="topnav">
<li><a [routerLink]="['Home']">Home</a></li>
<li><a [routerLink]="['Posts']">Articles</a></li>
<li><a href="#p">Publisher</a></li>
<li><a [routerLink]="['Login']">Login</a></li>
</ul>
<router-outlet></router-outlet>
Main.ts
import { bootstrap } from '@angular/platform-browser-dynamic';
import { AppComponent } from './app.component';
import { HTTP_PROVIDERS } from '@angular/http';
import { ROUTER_PROVIDERS } from '@angular/router-deprecated';
bootstrap(AppComponent, [ROUTER_PROVIDERS, HTTP_PROVIDERS]);

只需为尝试访问的未定义的每条路线添加路线,并将其重定向到您的主路线:
@RouteConfig([
{ path: '/home', name: 'Home', component: HomeComponent },
{ path: '/articles', name: 'Posts', component: PostsComponent },
{ path: '/detail/:id', name: 'PostDetail', component: PostDetailComponent },
{ path: '/login', name: 'Login', component: LoginComponent },
{ path: '/**', redirectTo: ['Home'] }
])

可能迟到了:
不推荐使用 useAsDefault
,请使用:
const appRoutes: Routes = [
{ path: 'crisis-center', component: CrisisListComponent },
{ path: 'heroes', component: HeroListComponent },
{ path: '', redirectTo: '/heroes', pathMatch: 'full' },
{ path: '**', component: PageNotFoundComponent }
];
答案 2 :(得分:0)
当你使用useasdefault时,它意味着你有一个父路线,并且在其中有子路线,即
localhost:8000/dashboard/dashboard
localhost:8000/dashboard/settings
两个网址路由将设置在父网址下,如下所示:
{path: '/dashboard/...', component:Dashboard}
然后在仪表板组件中,您现在创建仪表板根目录和设置路径作为子路径,如下所示:
{path: 'dashboard', component:DashboardAdmin, useAsDefault: True}
{path: 'settings', component:Settings}
在你的情况下,找出你需要封装的东西。例如,home, article
和detail
可以在一个父网址下面说:
{path: '/home/...' component: HomeDataComponent}
{ path: '/login', name: 'Login', component: LoginComponent },
然后将三个网址配置移动到HomeDataComponent
或您给它的名称:
@RouteConfig([
{ path: '/home', name: 'Home', component: HomeComponent , useAsDefault : true},
{ path: '/articles', name: 'Posts', component: PostsComponent },
{ path: '/detail/:id', name: 'PostDetail', component: PostDetailComponent },
])
使用useAsDefault
时,您需要首先显示父路线和子路线上的useAsDefault
。
检查this以获取详细说明。希望它有效。
