如何获取Nestjs中的所有路由(来自每个模块上可用的所有模块和控制器)？

import { Module, NestModule, MiddlewareConsumer, RequestMethod } from '@nestjs/common';
import { DiscoveryModule, DiscoveryService, Reflector } from '@nestjs/core';

@Module({
  imports: [DiscoveryModule],
})
export class AppModule implements NestModule {
  constructor(private readonly discoveryService: DiscoveryService) {}

  configure(consumer: MiddlewareConsumer) {
    // 你的中间件配置
  }
}

@Injectable()
export class RouteService {
  constructor(
    private readonly discoveryService: DiscoveryService,
    private readonly reflector: Reflector,
  ) {}

  getRoutes(): any[] {
    const controllers = this.discoveryService.getControllers();
    const routes = controllers.map((controller) => ({
      module: this.reflector.get<string>('moduleName', controller),
      path: this.reflector.get<string>('path', controller),
      routes: this.discoveryService
        .getRoutes(controller)
        .map((route) => ({
          path: this.reflector.get<string>('path', route),
          method: RequestMethod[route.requestMethod],
        })),
    }));
    return routes;
  }
}

@Controller('cats')
export class CatsController {
  @Get()
  findAll(): string {
    return 'This action returns all cats';
  }
}

@Module({
  controllers: [CatsController],
})
export class CatsModule {}

@Injectable()
export class AppService {
  constructor(private readonly routeService: RouteService) {}

  getAllRoutes(): any[] {
    return this.routeService.getRoutes();
  }
}
