javascript - Angular 2 使用不同的 url 路由到同一组件

Question

例如，如何路由到具有不同 url 和不同数据的同一组件

/exports/open  -  ExportsListComponent data: {exportstatus: 'open'}

/exports/submitted - ExportsListComponent data: {exportstatus: 'submitted'}

/exports/completed - ExportsListComponent data: {exportstatus: 'completed'}

这就是我尝试做的，我还有其他使用 ExportComponent 的路由，但具有类似的路由，例如exports/:exportId。

      { path: 'exports/jobs/:exportJobId', component: ExportComponent, canActivate: [RouteGuard], resolve: { exportJob: ExportJobResolver }, data: { allowed: ['inv', 'cr'] } },
      { path: 'exports/:exportId', component: ExportComponent, canActivate: [RouteGuard], resolve: { export: ExportResolver }, data: { allowed: ['inv', 'cr'] } },
      { path: 'exports', component: ExportsListComponent,
      children: [
        { path: 'open', component: ExportsListComponent ,  data: {exportstatus: 'open'}},
        { path: 'submitted', component: ExportsListComponent,  data: {exportstatus: 'submitted'} },
        { path: 'completed', component: ExportsListComponent, data: {exportstatus: 'completed'} }
      ],

当我使用/exports/open 访问 url 时遇到的问题是路由到 ExportComponent 而不是 ExportListComponent。如何使用 url 路由到导出/打开并路由到 ExportListComponent，而不是 ExportComponent。问题是当我路由到/exports/open 时，它会认为“open”是一个 id，但我需要路由到 ExportListComponent

根据official documentation :

The order of the routes in the configuration matters and this is by design. The router uses a first-match wins strategy when matching routes, so more specific routes should be placed above less specific routes.

因此，您必须将exports/:exportId 路由条目移至exports 条目下方。

像这样

  { path: 'exports/jobs/:exportJobId', component: ExportComponent, canActivate: [RouteGuard], resolve: { exportJob: ExportJobResolver }, data: { allowed: ['inv', 'cr'] } },
  { path: 'exports', component: ExportsListComponent,
  children: [
    { path: 'open', component: ExportsListComponent ,  data: {exportstatus: 'open'}},
    { path: 'submitted', component: ExportsListComponent,  data: {exportstatus: 'submitted'} },
    { path: 'completed', component: ExportsListComponent, data: {exportstatus: 'completed'} }
  ],
  {path: 'exports/:exportId', component: ExportComponent, canActivate: [RouteGuard], resolve: { export: ExportResolver }, data: { allowed: ['inv', 'cr'] } },
