如何在Nestjs中扩展多个dto类

// user.dto.ts
import { IsString, IsEmail } from 'class-validator';

export class CreateUserDto {
  @IsString()
  name: string;

  @IsEmail()
  email: string;

  @IsString()
  password: string;
}

// post.dto.ts
import { IsString, IsNotEmpty } from 'class-validator';

export class CreatePostDto {
  @IsNotEmpty()
  @IsString()
  title: string;

  @IsNotEmpty()
  @IsString()
  content: string;
}

import { Controller, Post, Body } from '@nestjs/common';
import { CreateUserDto, CreatePostDto } from './dto';

@Controller('users')
export class UsersController {
  @Post()
  createUser(@Body() createUserDto: CreateUserDto) {
    // 处理创建用户的逻辑
  }
}

@Controller('posts')
export class PostsController {
  @Post()
  createPost(@Body() createPostDto: CreatePostDto) {
    // 处理创建文章的逻辑
  }
}

// user.dto.ts
import { IsString, IsEmail } from 'class-validator';
import { CreateUserDto } from './create-user.dto';

export class UpdateUserDto extends CreateUserDto {
  @IsString()
  name: string;

  @IsEmail()
  email: string;
}

@Controller('users')
export class UsersController {
  @Put(':id')
  updateUser(@Param('id') id: string, @Body() updateUserDto: UpdateUserDto) {
    // 处理更新用户的逻辑
  }
}
