## 邮件服务 ##

#### 安装邮件模块 ####

yarn add @nestjs-modules/mailer nodemailer
    #or
    npm install --save @nestjs-modules/mailer nodemailer

#### 安装模板引擎 ####

yarn add handlebars
    #or
    yarn add pug
    #or
    yarn add ejs

#### 新建邮件模块、控制器、服务 ####

nest g module modules/email
    nest g co modules/email --no-spec
    nest g service modules/email --no-spec

#### 配置邮件模块 ####

app.module.ts

import {  MailerModule } from '@nestjs-modules/mailer'
    import {  PugAdapter} from '@nestjs-modules/mailer/dist/adapters/pug.adapter'
    import {  EmailModule } from './modules/email/email.module';
    import * as path from 'path';
    
    @Module({ 
    	imports: [
    		EmailModule,
    		MailerModule.forRootAsync({ 
    			useFactory: () => ({ 
    				transport: 'smtps://xxx@qq.com:cfooznddrnnncihj@smtp.qq.com',
    				defaults: { 
    					from: '"domain.com" <no-reply@domain.com>'
    				},
    				template: { 
                        // dir: process.cwd() + '/src/template/', // 这一句不用配置，可以找到路径
                        dir: path.join(__dirname, './template'),
    					adapter: new PugAdapter(),
    					options: { 
    						strict: true
    					}
    				}
    			})
    		})
    	],
    	controllers: [AppController],
    	providers: [AppService],
    })
    export class AppModule {  }

**注意：**

1.  `transport: 'smtps://3472569282@qq.com:cfooznddrnnncihj@smtp.qq.com', a. cfooznddrnnncihj这个需要在邮箱设置中允许配置获取秘钥`
2.  使用dir: `path.join(__dirname, './template')`会提示在dist路径下找不到，需要在nest-cli.json中配置：
    
        { 
          "collection": "@nestjs/schematics",
          "sourceRoot": "src",
          "compilerOptions": { 
              "assets": ["template/**/*"]
          }
        }

#### 配置控制器 ####

import {  Controller, Get } from '@nestjs/common';
    import {  EmailService } from './email.service';
    
    @Controller('email')
    export class EmailController { 
        
        constructor(private readonly emailService: EmailService) { }
    
        @Get()
        sendEmail() { 
            this.emailService.sendEmail();
            return 'ok';
        }
    }

#### 配置服务 ####

import {  Injectable } from '@nestjs/common';
    import {  MailerService } from '@nestjs-modules/mailer';
    
    @Injectable()
    export class EmailService { 
    
        constructor(private readonly mailerService: MailerService) { }
    
        sendEmail () { 
            this.mailerService.sendMail({ 
                to: 'xxx@163.com', // 接收信息的邮箱
                from: 'xxx@qq.com', // 要发送邮件的邮箱
                subject: 'Love You √',
                // html: '<b>welcome !</b>',
                template: 'email',
            })
        }
    }

#### 模板内容 ####

在src根目录下template/email.pug

doctype html
    html(lang="en")
        head
            title 嗨
        body
            h1 cute girl
            #container.col
            p 喜
            p 欢
            p 你
            ul
                li LOVE YOU .

## 定时任务 ##

[https://docs.nestjs.com/techniques/task-scheduling][https_docs.nestjs.com_techniques_task-scheduling]

#### 安装地址 ####

npm install --save @nestjs/schedule

#### 配置 ####

将ScheduleModule导入到根目录AppModule并运行forRoot()静态方法  
tasks.module.ts

import {  Module } from '@nestjs/common';
    import {  TasksService } from './tasks.service';
    import {  ScheduleModule } from '@nestjs/schedule';
    import {  EmailService } from '../email/email.service';
    @Module({ 
      providers: [TasksService, EmailService],
      imports: [ScheduleModule.forRoot()]
    })
    export class TasksModule { }

#### 服务配置 ####

tasks.service.ts

import {  Injectable, Logger } from '@nestjs/common';
    import {  Cron, Interval, Timeout} from '@nestjs/schedule';
    import {  EmailService } from '../email/email.service';
    
    @Injectable()
    export class TasksService { 
        private readonly logger = new Logger(TasksService.name)
        
        constructor(private readonly emailService: EmailService) { }
    
        @Cron('45 * * * * *')
        handleCron() { 
            this.logger.debug('该方法将在45秒标记处每分钟运行一次');
        }
    
        @Interval(10000)
        handleInterval() { 
            this.logger.debug('2');
        }
    
        @Timeout(5000)
        handleTimeout() { 
            this.logger.debug('3')
        }
    
        @Interval(10000)
        sendEmail() { 
            this.emailService.sendEmail();
        }
    }
