在@NgModule中使用从后端加载的变量导入标记

// app-routing.module.ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  // ... 其他路由配置
];

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

// app.component.ts
import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  constructor(private router: Router) {}

  ngOnInit() {
    // 假设从后端获取的模块列表
    const modulesToLoad = ['moduleA', 'moduleB'];

    // 动态加载模块
    modulesToLoad.forEach(moduleName => {
      import(`./${moduleName}/${moduleName}.module`).then((module) => {
        const moduleInstance = module[moduleName + 'Module'];
        this.router.config.push({
          path: `/${moduleName.toLowerCase()}`,
          loadChildren: () => moduleInstance
        });
        this.router.resetConfig(this.router.config);
      });
    });
  }
}
