Nodejs获取桌面截图，并定时发送给指定邮箱
npm install --save screenshot-desktop //截图
npm install --save nodemailer //发邮件
npm install --save node-schedule //定时
发邮件用的包 网址： https://nodemailer.com/about/
const screenshot = require('screenshot-desktop')
const nodemailer = require('nodemailer')
const schedule = require('node-schedule')
const fs = require('fs')//nodejs 文件操作的包
var transporter = nodemailer.createTransport({
host:"smtp服务器地址",
secure:true,
port:端口, //端口注意了 分两种，一种是有ssl的一种是没有ssl
auth: {
user: "发送的邮箱",
pass: "密码"
},
debug: true // include SMTP traffic in the logs
});
设置每一分钟发送一次
var rule = new schedule.RecurrenceRule();
rule.second = 10;
var j = schedule.scheduleJob(rule,function(){
})
screenshot()
.then((img) => {
//将截取的图片存入根目录out.jpg
fs.writeFile('out.jpg', img,function(err){
if(err){
throw err
}
console.log('written to out.jpg')
});
})
看了官方的example才知道，图片要写到下面的attachments中，并提供cid，给上面html中的img调用。
var message = {
from:"发送邮件地址",
to:"接受邮件地址",
subject:"桌面截图",
html:'桌面截图：<img src="cid:test"/>',
//附加文件，提供cid给上面的img调用
attachments:[
{
filename: 'out',
path: __dirname + '/out.jpg',
cid: 'test' // should be as unique as possible
}
]
}
transporter.sendMail(message, (error, info) => {
if (error) {
console.log('Error occurred');
console.log(error.message);
return;
}
console.log('Message sent successfully!');
console.log('Server responded with "%s"', info.response);
transporter.close();
});
