Angular 2路线:不为儿童呼吁解决 [英] Angular 2 routes: resolve not called for children

问题描述

使用:

"@angular/core": "2.2.2",
"@angular/router": "3.2.2",

路线如下:

export const rootRouterConfig: Routes = [
  {
    path: '', resolve: { profile: PrefetchProfileService },
    children: [
      {path: '', component: Pages.LandingComponent, pathMatch: 'full'},
      {path: 'pl', component: PersonalLoanComponent},
      {path: 'login', component: Pages.LoginComponent, canActivate: [ExistingSessionGuard]},
      {path: 'register', component: Pages.RegisterComponent, canActivate: [ExistingSessionGuard]},
      {path: 'home', component: Pages.HomeComponent, canActivate: [AuthGuard]},
    ]
  }
];

问题在于，解析不会触发任何直接导航到子路径的操作.例如:如果用户直接导航到/login，则不会调用PrefetchProfileService.如果用户导航到/，然后转到/login，则一切正常.我该如何正确处理?

The issue is that resolve is not triggering for any direct navigation to a child path. Ex: if user navigates directly to /login, PrefetchProfileService is not called. If user navigates to /, then goes to /login, everything is fine. How do I deal with this correctly?

推荐答案

您必须在要使用PrefetchProfileService的每个子路由中添加resolve.

You have to add resolve in each child route you want to use PrefetchProfileService.

path: '', resolve: { profile: PrefetchProfileService },
        children: [
          {path: '', component: Pages.LandingComponent,resolve: { profile: PrefetchProfileService } ,pathMatch: 'full'},
          {path: 'pl', resolve: { profile: PrefetchProfileService },component: PersonalLoanComponent},
          {path: 'login', resolve: { profile: PrefetchProfileService },component: Pages.LoginComponent, canActivate: [ExistingSessionGuard]},
          {path: 'register', resolve: { profile: PrefetchProfileService },component: Pages.RegisterComponent, canActivate: [ExistingSessionGuard]},
          {path: 'home',resolve: { profile: PrefetchProfileService } ,component: Pages.HomeComponent, canActivate: [AuthGuard]}
