如何在NestJS中使用相同的类更改嵌套对象中的验证

import { IsString, IsEmail, ValidateNested } from 'class-validator';

class UpdateUserDto {
  @IsString()
  name: string;

  @IsEmail()
  email: string;
}

import { ValidateNested } from 'class-validator';
import { Type } from 'class-transformer';

class UpdateProfileDto {
  @ValidateNested()
  @Type(() => UpdateUserDto)
  user: UpdateUserDto;
}

import { Injectable } from '@nestjs/common';
import { validate } from 'class-validator';

@Injectable()
class ProfileService {
  async updateProfile(updateProfileDto: UpdateProfileDto): Promise<void> {
    const errors = await validate(updateProfileDto);
    if (errors.length > 0) {
      // 处理验证错误
    }
    // 执行更新操作
  }
}
