Angular 6.1.9嵌套到命名插座的路由-“无法匹配任何路由”错误

我将 Angular 6.1.9 及其路由器模块一起使用。我似乎无法路由/显示已命名的插座内容。

调用<a [routerLink]="['', { outlets: { editArea: ['addRootPartner'] } }]">foo</a>时,它崩溃并显示:

  

NavigationError(id:2,url:'/ overview / work / allPartners(editArea:addRootPartner)',错误:错误:无法匹配任何路由。URL段:'addRootPartner')


我的应用程序结构为:

app.module
app-routing.module

workspace.module
workspace-routing.module

应用路由

const rootAppRoutes: Routes = [
  { path: '',  redirectTo: 'overview', pathMatch: 'full' },
  { path: 'overview', loadChildren: './overview/workplace/workplace.module#WorkplaceModule' },
  { path: '**', component: PageNotFoundComponent }
];

重定向到overview模块,该模块加载了workplace模块。

工作场所路由

const workplaceRoutes: Routes = [
  { path: '', redirectTo: 'work', pathMatch: 'full'},
  { path: 'work', component: WorkplaceComponent, children: [
    { path: 'allPartners', component: RootPartnersComponent },
    { path: 'childPartners', component: ChildPartnersComponent },
    { path: '', redirectTo: 'allPartners', pathMatch: 'full'}
  ]},
  { path: 'addRootPartner', component: AddRootPartnerComponent, outlet: 'editArea' }
];

重定向到显示work的{​​{1}}。然后它进一步显示到子WorkplaceComponent,其中显示allPartners


在代码中,我使用了两个RootPartnersComponent。一个在组件<router-outlet>模块内部:

app

第二个是在<router-outlet></router-outlet> 模块的workplace中:

WorkplaceComponent

此设置有什么问题?嵌套命名网点的使用有技术限制吗?

答案 0 :(得分:5)

好的,经过一整夜的混乱之后,我找到了解决方法。


首先,在具有path: ''的父级下定义的命名出口子路由无效。

// the root redirect due to named outlets not being able to work as children of "path: ''"
{ path: '', redirectTo: 'work', pathMatch: 'full' },
{ path: 'work', component: WorkplaceComponent, children: [
   { path: '', component: RootPartnersComponent, outlet: 'displayArea' },
   { path: 'childPartners', component: ChildPartnersComponent, outlet: 'displayArea' },
   // child for edit area outlet
   { path: 'addRootPartner/:id', component: AddRootPartnerComponent, outlet: 'editArea' }
]}

第二个问题与路由器链接有关。显然,您必须将父路线指定为导航的基础。因此,导航必须以编程方式完成。

this.router.navigate([
  // NOTE: No relative-path navigation is required because we are accessing
  // the parent's "activatedRoute" instance. As such, this will be executed
  // as if we were doing this in the parent view component.
  {
    outlets: {
      editArea: ['addRootPartner']
    }
  }
],
  {
    relativeTo: this.activatedRoute.parent // <--- PARENT activated route.
  }
);

超级后期编辑:

path: ''的问题可能是由于将此路由配置为第一个路由。

  

配置中的路由顺序很重要,这是设计使然。路由器在匹配路由时会使用“先赢”策略,因此应将更具体的路由放在不那么具体的路由之上。在上面的配置中,首先列出具有静态路径的路由,然后是与默认路由匹配的空路径路由。通配符路由排在最后,因为它匹配每个URL,并且只有在没有其他路由最先匹配时才应选择通配符路由。
