路由上的 Angular2 路由器数据 属性

Question

我的 app-routing 模块中有这些路线：

{
  path: 'some',
  canActivate: [AuthGuard],
  data: {
    auth: {
      test: "theTest"
    },
  },
  children: [
    {
      path: '',
      pathMatch: 'full',
      component: SomeComponent,
      canActivate: [AuthGuard],
      resolve: {
        something: SomethingResolver
      }
    },
  ]
}

在 AuthGuard CanActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) 中，如果我执行 console.log(route.data["auth"] 并获得 {test: "theTest"} 两次。

做 children "adopt" parents 的数据？

Answer 1

你在复制东西，子数组中的 path : 'some' 和 path: '' 指向相同的路由，只在子数组中放置 canActivate: [AuthGuard] 所以 canActivate 会只执行一次：

{
  path: 'some',
  data: {
      auth: {
         test: "theTest"
      }
   },
  children: [
    {
      path: '',
      pathMatch: 'full',
      component: SomeComponent,
      canActivate: [AuthGuard],
      resolve: {
        something: SomethingResolver
      }
    },
  ]
}
