我有一个主路线，有儿童路线，那些孩子是懒惰加载模块，在每个延迟加载模块，我也有他们单独的路由 . 我遇到的问题是当我守卫主路线以防止加载多次调用的子路由时
主要路由代码
export const PROVIDER_ROUTES: Route = {
path: 'provider',
component: ProviderComponent,
canActivateChild:[AuthGuard],
children: [
{ path: '', redirectTo: 'courses', pathMatch: 'full' },
{ path: 'courses', loadChildren: 'app/provider/course/course.module#CourseModule' },
],
};
延迟加载路由代码
const routes: Routes = [
{
path: '',
component: CourseListComponent,
resolve: { courses: CourseListResolver },
children: [
{
path: ':id',
component: CoursesEditComponent,
resolve: { organizations: AddCourseResolver }
},
{
path: ':id/edit',
component: CoursesEditComponent,
resolve: { course: CourseEditResolver }
},
{
path: ':id/assign/:orgId',
component: CourseAssignComponent,
resolve: { subOrganizations: LicenseAssignResolver }
},
{
path: ':id/update/:orgId',
component: CourseAssignComponent,
resolve: { license: LicenseEditResolver }
}
]
},
];
@NgModule({
imports: [RouterModule.forChild(routes)],
providers: [
CourseListResolver,
CourseEditResolver,
LicenseAssignResolver,
LicenseEditResolver,
AddCourseResolver
],
exports: [RouterModule],
})
export class CourseRoutingModule { }
export const RoutedComponents = [
CourseListComponent,
CoursesEditComponent,
CourseAssignComponent
];
AuthGuard代码是
export class AuthGuard implements CanActivateChild {
constructor(private authService: AuthService, private router: Router, private commonService:CommonService) { }
canActivateChild(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> {
return this.authService.isUserLoggedIn().map((result: EditUser) => {
console.log(result);
if (result != null && result.organizations.length > 0) {
this.commonService.isAuthenticated = true;
return true;
}
this.commonService.isAuthenticated = false;
this.router.navigate(["/provider"])
return false;
});
AuthGuard函数多次调用为什么？

你有两个级别的激活路线，所以它将检查每个级别的守卫 . 如果你想让它调用一次，只需将警卫向下移动到子级别 .
@Adawg的意思是：
将 canactivatechild 放在延迟加载的路由部分而不是根路由中
