实现对于一些指定数据超过预期的时候,会发送邮件报警 代码地址:https://github.com/klren0312/stm32_wifi 2017.4.29
(1)emailjs模块 send emails, html and attachments (files, streams and strings) from node.js to any smtp server (2)github网址 https://github.com/eleith/emailjs (3)安装
npm install emailjs --save
定时使用前面说过的node-schedule模块
(1)引入相关模块
var email = require("emailjs");//发送邮件模块
var mysql = require('mysql');//mysql模块
var schedule = require('node-schedule');//定时模块
(2)配置数据库
//数据库配置
var conn = mysql.createConnection({
host:'localhost',
user:'root',
password:'root',
database:'nodemysql',
port:3306
})
//连接数据库
conn.connect();
(3)发送邮箱的配置
//配置邮箱
var server = email.server.connect({
user: "xxx@xxx.com",//邮箱用户名
password:"xxxxxx",//密码
host:"smtp服务器的地址",//查看使用的邮箱的smtp服务器地址
ssl:true
});
(4)定时发送
//每分钟第十秒的时候检测
var rule = new schedule.RecurrenceRule();
rule.second = 10;//定义为每分钟第十秒
var j = schedule.scheduleJob(rule,function(){
//数据库查询
conn.query('SELECT * FROM pet',function(err,rows,fields){
//例如获取温度的值,存入tem
var tem = rows[rows.length-1].tem;
//定义邮件内容
var temmsg = {
text:"tempreture is " + tem + ",please be careful",//邮件内容
from: "15755022403@139.com",//发送方
to:"605747907@qq.com",//接收方
subject:"PetHose tem"
};
//判断如果温度大于或等于30度,就发送邮件通知
if(tem>=30){
//邮件发送
server.send(temmsg,function(err,message){
console.log(err || "ok");
});
}
});
});
(1)当温度大于或等于三十度的时候,发送邮件
接收到的报警邮件
