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}}
}
