我想使用 IP 地址构建简单的身份验证，我列入白名单的某些 IP 地址可以访问 API。但是当我request.ip只使用它时，我遇到了一个问题::1，它的输出不是真实的IP地址。

如何在nestjs中获取用户IP地址？这是我现在的代码

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 { …

问题

我的安装可能存在一些问题，better-sqlite3因为当我尝试执行我的index.js（单击以在pastebin上显示它）时

node index.js

总是有相同的结果。我在 MacOS 上尝试过，它可以工作，但在我的机器上基于 Linux Lite Ubuntu 的发行版中，它没有给我以下相同的错误：

我的目的是什么？ …

我创建了一个像这样的守卫

import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { AuthService } from './auth.service';

@Injectable()
export class CompanyGuard implements CanActivate {
  constructor(private readonly authService: AuthService) {}

  async canActivate(context: ExecutionContext): Promise<boolean> {
    const request = context.switchToHttp().getRequest();
    const token = request.headers['token'];
    if (token) {
      const company = await this.authService.validateToken(token);
      return company ? true : false;
    } else {
      return false;
    }
  }
}

我想将 Company 的值保留在请求对象上，以便稍后可以在控制器上使用它。如何在 Nest.js 中做到这一点？我试图在文档中查看它，但我很困惑。我应该使用会话还是有更简单的方法来做到这一点？
