起步

npm i -g @nestjs/cli

创建项目

nest new project-name

创建 Module

modules文件下的user

nest g module user modules

创建 Controller

nest g controller user modules

创建 Provider

nest g service user modules

直接生成一个CRUD模块的navigation，选择PEST API

 nest g resource navigation  modules

配置swagger

新建文件src/swagger/index.ts

import { DocumentBuilder, SwaggerModule } from '@nestjs/swagger';

const swaggerOptions = new DocumentBuilder()
    .setTitle('小白龙博客接口文档')
    .setDescription('小白龙博客文档')
    .setVersion('1.0.0')
    .addBearerAuth()
    .build();

export function createSwagger(app) {
    const document = SwaggerModule.createDocument(app, swaggerOptions);
    SwaggerModule.setup('swagger-doc', app, document);
}

配置功能模块标签与接口名字

import { LinksSetDto } from './dto/links.set.dto';
import { ApplyLinksService } from './apply-links.service';
import { ApiTags, ApiOperation } from '@nestjs/swagger';
import { Controller, Get, Post, Query, Body } from '@nestjs/common';

@ApiTags('申请友链')
@Controller('apply-links')
export class ApplyLinksController {
    constructor(private readonly applyLinksService: ApplyLinksService) {}

    @Get('/set')
    @ApiOperation({ summary: '创建申请友链' })
    set(@Query() params: LinksSetDto) {
        return this.applyLinksService.set(params);
    }

    @Get('/query')
    @ApiOperation({ summary: '获取申请友链列表' })
    query(@Query() params) {
        return this.applyLinksService.query(params);
    }

    @Post('/del')
    @ApiOperation({ summary: '删除{id}申请友链' })
    del(@Body() params) {
        return this.applyLinksService.del(params);
    }
}
