错误：无法匹配任何路由。 URL 段：“游乐设施”

Question

我收到此错误，但没有找到我错的地方。

路线如下，

const routes: Routes = [
  {path: 'login', component: LoginComponent},
  {path: 'register-user', component: RegisterUserComponent},
  {path: '', redirectTo: '/login', pathMatch: 'full'},
  {path: 'dash', component: SideNavComponent,
  children: [
    {path: 'rides', component: RidesComponent,  pathMatch: 'full'}
  ]}];

app.component.html 是，

<router-outlet></router-outlet>

SideNavComponent HTML 是，

<mat-sidenav-container class="sidenav-container">
  <mat-sidenav
    #drawer
    class="sidenav"
    fixedInViewport="true"
    [attr.role]="(isHandset$ | async) ? 'dialog' : 'navigation'"
    [mode]="(isHandset$ | async) ? 'over' : 'side'"
    [opened]="!(isHandset$ | async)">
    <mat-toolbar> 
      <div class="logo-container">
      <img src="/assets/images/Yaana-logo-white.png" class="logoDiv"/>
      </div>  
    </mat-toolbar>
    <mat-nav-list>
      <a mat-list-item href="#">Link 1</a>
      <a mat-list-item href="#">Link 2</a>
      <a mat-list-item href="#">Link 3</a>
      <nav class="sidenavbutton">
        <button class="cmpbtn" mat-button (click)="onUserInfoClicked()">User Info<mat-icon id="icon">{{userInfoIcon}}</mat-icon></button>
        <ul class="subbtn" *ngIf="showUserSubs === true">
            <li class="sub-menu"> <a routerLink="/rides" routerLinkActive="active">Rides </a></li>
        </ul>
      </nav>
    </mat-nav-list>
  </mat-sidenav>
  <mat-sidenav-content>
    <mat-toolbar color="accent">
      <button
        type="button"
        aria-label="Toggle sidenav"
        mat-icon-button
        (click)="drawer.toggle()"
        *ngIf="isHandset$ | async">
        <mat-icon aria-label="Side nav toggle icon">menu</mat-icon>
      </button>
      <span></span>
    </mat-toolbar>
   <router-outlet></router-outlet>
  </mat-sidenav-content>
</mat-sidenav-container>

SideNavComponent 包含 用于在工具栏下方显示 SideNavComponent 的子组件。

但是当我尝试导航到 RidesComponent 时

http://localhost:4200/dash/rides

，我收到以下错误，

Answer 1

原因

<a routerLink="rides" routerLinkActive="active">Rides </a></li>

工作和

<a routerLink="/rides" routerLinkActive="active">Rides </a></li>

这不是那个，

第一个是相对路径，第二个是绝对路径。

因此，当您单击第一个链接时，angular 会将 routerLink 附加到当前路径，而在第二个链接中，angular 会将其附加到应用程序上下文根目录，而不考虑当前 url。

我希望有人能从中受益。 :)。

Answer 2

您似乎忘记添加<base href="/">。请在index.html中添加此内容。

Answer 3

{path: 'rides', component: RidesComponent} 可以达到目的，这里不需要pathMatch: 'full'，我觉得休息很好。

Answer 4

经过一些试验，我找到了解决办法，是routerlink部分的问题，

这是我所做的更改，

 <li class="sub-menu"> <a routerLink="rides" routerLinkActive="active">Rides </a></li>

现在可以正常工作了。

Answer 5

<li class="sub-menu"> <a routerLink="/dash/rides" routerLinkActive="active">Rides </a></li>
