我是nestJs的新手，我需要添加基于角色的应用程序访问，所以我按照文档，但在执行上下文中用户不存在.我似乎找不到问题，如果你需要更多的代码，这里是github repo：https://github.com/anjula-sack/slinc-backend

角色.防护.ts

import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { Reflector } from '@nestjs/core';
import { ROLES_KEY } from 'src/decorators/roles.decorator';
import Role from 'src/util/enums/role.enum';

@Injectable()
export class RolesGuard implements CanActivate {
  constructor(private reflector: Reflector) {}

  canActivate(context: ExecutionContext): boolean {
    const requiredRoles = this.reflector.getAllAndOverride<Role[]>(ROLES_KEY, [
      context.getHandler(),
      context.getClass(),
    ]);
    if (!requiredRoles) {
      return true;
    }
    const { user } = context.switchToHttp().getRequest();
    console.log(context.switchToHttp().getRequest().req);

    return requiredRoles.some((role) => user.type === role);
  }
}

应用程序控制器.ts

@UseGuards(JwtAuthGuard, RolesGuard)
  @Get('me/business')
  @Roles(Role.ADMIN)
  getBusiness(@Request() req) {
    return this.usersService.getUserBusiness(req.user.id);
  }
