问如何从请求上下文nestjs获取IP地址？

EN

import {
  Injectable,
  CanActivate,
  ExecutionContext,
  Logger,
} from '@nestjs/common';
import { Observable } from 'rxjs';

@Injectable()
export class AuthGuard implements CanActivate {
  canActivate(
    context: ExecutionContext,
  ): boolean | Promise<boolean> | Observable<boolean> {
    const request = context.switchToHttp().getRequest();
    const allowedIp: Array<string> = ['129.2.2.2', '129.2.2.2'];
    if (process.env.ENV === 'production') {
      const ip = request.connection.remoteAddress;
      Logger.log(ip, 'ACCESSED IP ADDRESS');
      if (allowedIp.includes(ip)) {
        return true;
      } else {
        return false;
      }
    } else {
      return true;
    }
  }
}
