如何将 child 组件设置为 router-outlet 的默认路由？

Question

我正在使用 Lazyloading 并且我有两个 router-outlets。当我想导航到另一条 child 路线时出现问题。我得到这个错误，

TypeError: Cannot read property 'split' of undefined at defaultUrlMatcher (router.js:566) at match (router.js:2221) .....

我的主要 app-router 模块看起来像，

const appRoutes: Routes = [
    { path: '', redirectTo: 'web/welcome' , pathMatch: 'full' },
    { path: 'web', redirectTo: 'web/welcome' , pathMatch: 'full' },
    {
        path: 'web',
        loadChildren: 'app/core/website/modules/website.module#WebSiteModule',
        data: { preload: true }
     },
    {
        path: 'dbapp', canActivate: [AuthGuardService],
        loadChildren: 'app/core/database/modules/db.module#DbModule',
        data: { preload: true }
     },
    { path: '**', redirectTo: '/404',  pathMatch: 'full'},
    { path: '**', component: NotFoundComponent, data: { message: 'We Could Not Serve Your Request!'}},
];

并且 dbapp 我有这个路由模块，

const dbRoutes: Routes = [
  {
    path: '',
    component: DbHomeComponent,
    data: { preload: true },
    pathMatch: 'full',
    children: [
      { path: '', component: UserDashboardComponent },
      {
        path: 'registry',
        canActivate: [RoleGuardService],
        data: { expectedRole: { roles: ['reg'] } },
        loadChildren:
          'app/core/database/database-cores/registry-core/modules/registry.module#RegistryModule'
        // canActivateChild: [RoleGuardService]
      },
      {
        path: 'embryology',
        canActivate: [RoleGuardService],
        data: { expectedRole: { roles: ['emb'] } },
        loadChildren:
          'app/core/database/database-cores/embryology-core/modules/embryology-routing.module#EmbryologyRoutingModule'
      },
      {
        path: 'nursing',
        canActivate: [RoleGuardService],
        data: { expectedRole: { roles: ['nur'] } },
        loadChildren:
          'app/core/database/database-cores/embryology-core/modules/embryology-routing.module#EmbryologyRoutingModule'
      }
    ]
  },
];

我的地图如下所示，

Router Map，下划线components是router-outlets

所以根据我的配置。路由从 https://www.artngcore.com:4200/web/welcome 开始，身份验证后路由更改为 https://www.artngcore.com:4200/dbapp

我设法导航到 UserDashboardComponent 作为默认路由，我的问题是如果我路由到另一个 children，即 routerLink="/dbapp/registry"

如何将 child 组件显示为默认路由并导航到其他 children 路由？

已解决，答案来源于、

所以我的dbapp路由模块应该是这样的，

const dbRoutes: Routes = [
  {
    path: '',
    component: DbHomeComponent,
    data: { preload: true },
    children: [
      { path: '', component: UserDashboardComponent },
      {
        path: 'registry',
        canActivate: [RoleGuardService],
        data: { expectedRole: { roles: ['reg'] } },
        loadChildren:
          'app/core/database/database-cores/registry-core/modules/registry.module#RegistryModule'
        // canActivateChild: [RoleGuardService]
      },
      {
        path: 'embryology',
        canActivate: [RoleGuardService],
        data: { expectedRole: { roles: ['emb'] } },
        loadChildren:
          'app/core/database/database-cores/embryology-core/modules/embryology-routing.module#EmbryologyRoutingModule'
      },
      {
        path: 'nursing',
        canActivate: [RoleGuardService],
        data: { expectedRole: { roles: ['nur'] } },
        loadChildren:
          'app/core/database/database-cores/embryology-core/modules/embryology-routing.module#EmbryologyRoutingModule'
      }
    ]
  }
];

我只需要更改路由匹配策略即可，pathMatch: 'full'不应该包含
