如何验证nest.js中的嵌套对象列表

npm install class-validator

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

class NestedObjectDTO {
  @IsString()
  name: string;

  @IsInt()
  age: number;
}

class MainDTO {
  @IsArray()
  @ValidateNested({ each: true })
  nestedObjects: NestedObjectDTO[];
}

import { Controller, Post, Body, UsePipes, ValidationPipe } from '@nestjs/common';

@Controller('example')
export class ExampleController {
  @Post()
  @UsePipes(new ValidationPipe())
  createExample(@Body() mainDto: MainDTO) {
    // 在这里处理验证通过的数据
  }
}
