nest.js-学习记录：7、crud操作api

接上一篇

posts.controller.ts
findByIdAndUpdate、find、create、findByIdAndDelete都是mongoose的方法，与nest.js无关

import { Body, Controller, Delete, Get, Param, Post, Put, Query } from '@nestjs/common';
import { ApiOperation, ApiProperty, ApiTags } from '@nestjs/swagger';
import { PostModel } from './posts.model';

// 标识创建帖子的参数详情
class createPostDto{
    @ApiProperty({description:'帖子标题'})
    title:string
    @ApiProperty({description:'帖子内容'})
    content:string
}

@Controller('posts')
@ApiTags('帖子')
export class PostsController {
  @Get()
  @ApiOperation({summary:'显示帖子列表'})
 async index() {
 	//查找帖子
    return await PostModel.find()
  }

  @Post()
  @ApiOperation({summary:"创建帖子"})
  // 获取post请求的数据用@Body()装饰器获取数据，get用@query()
 async create(@Body() Body:createPostDto){
 	//创建帖子
    await PostModel.create(Body)
    return{
      success:true
    }
  }

  @Get(':id')
  @ApiOperation({summary:"帖子详情"})
  async detail(@Param('id') id:string){
  	//根据id查帖子
    return await PostModel.findById(id)
  }

  @Put(':id')
  @ApiOperation({summary:'编辑帖子详情'})
  async update(@Param('id') id:string,@Body() body:createPostDto){
  //根据id修改帖子
    await PostModel.findByIdAndUpdate(id,body)
    return {
      success:true
    }
  }
  @Delete(':id')
  @ApiOperation({summary:'删除帖子'})
  async remove(@Param('id') id:string){
  //根据id删除帖子
    await PostModel.findByIdAndDelete(id)
    return{
      success:true
    }
  }
}
