如何在Nestjs验证中以Object的形式获取异常错误？

npm install class-validator

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

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

  @IsEmail()
  email: string;

  @IsString()
  password: string;
}

import { Controller, Post, Body, UsePipes, ValidationPipe } from '@nestjs/common';
import { CreateUserDto } from './dto/create-user.dto';

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

import { ExceptionFilter, Catch, ArgumentsHost, BadRequestException } from '@nestjs/common';

@Catch(BadRequestException)
export class ValidationExceptionFilter implements ExceptionFilter {
  catch(exception: BadRequestException, host: ArgumentsHost) {
    const ctx = host.switchToHttp();
    const response = ctx.getResponse();
    const { message } = exception;

    response.status(400).json({
      statusCode: 400,
      message: 'Validation failed',
      errors: message,
    });
  }
}

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ValidationExceptionFilter } from './filters/validation-exception.filter';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.useGlobalFilters(new ValidationExceptionFilter());
  await app.listen(3000);
}
bootstrap();
