过滤从查询参数传入的数组。NestJS，TypeORM

import { Controller, Get, Query } from '@nestjs/common';

@Controller('example')
export class ExampleController {
  @Get()
  findAll(@Query('ids') ids: number[]) {
    // 在这里处理传入的数组数据
    // ...
  }
}

import { EntityRepository, Repository } from 'typeorm';
import { ExampleEntity } from './example.entity';

@EntityRepository(ExampleEntity)
export class ExampleRepository extends Repository<ExampleEntity> {
  async findFilteredByIds(ids: number[]): Promise<ExampleEntity[]> {
    const query = this.createQueryBuilder('example');
    query.whereInIds(ids);
    return query.getMany();
  }
}

import { Controller, Get, Query } from '@nestjs/common';
import { ExampleRepository } from './example.repository';

@Controller('example')
export class ExampleController {
  constructor(private readonly exampleRepository: ExampleRepository) {}

  @Get()
  async findAll(@Query('ids') ids: number[]) {
    const filteredExamples = await this.exampleRepository.findFilteredByIds(ids);
    // 在这里处理过滤后的数据
    // ...
    return filteredExamples;
  }
}
