Question

我需要根据服务方法返回的条件动态定义解析器。这是路由文件中的代码：

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';
import {MyComponent} from './components/myComponent/myComponent.component';
import {TestResolver} from './../_resolvers/test.resolver';
import {OtherResolver} from '../_resolvers/other.resolver';
import {PrivilegesCheckerService} from './../auth/_services/privileges_checker.service';

const routes: Routes = [
  {
      path: '',
      component: MyComponent,
      resolve: {
          item: OtherResolver
      }
    }
];

//  Get the test data only if the user has the 'TEST_PRIVILEGE' privilege --> This doesn't work
if(this.privilegesCheckerService.checkPrivileges(['TEST_PRIVILEGE'])) {
    routes[0].resolve.test = TestResolver;
}

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class AuthRoutingModule {
}

当我通常在组件内部使用服务时，我导入服务，将其声明到组件的构造函数中，并像this.myService.myMethod()一样使用它，但是在这种情况下，它不起作用，因为this在export class AuthRoutingModule { }声明之外无效。我收到的错误与服务定义文件中不存在的currentUser（存储在localStorage中）有关（我不确定这是否相关）。请指教。谢谢！
