功能 每天定时截图,并把截到的图片自动通过邮件发送。 说明 代码注释已经非常详细,就不多做说明,需要的朋友自己查看代码即可,主文件Mail.js,截图文件capturePart1.js,capturePart2.js,capturePart3.js,这里只展示了capturePart1.js其他两个类似。值得注意的是有登录权限的网站一定要设置Cookie,需要截取高质量图片的话截取时间一定设置长一些。 Mail.js /************************************************************************************************************ * 定时发送邮件功能说明: * node.js必备安装模块:node_modules-->phantomjs,nodemailer,node-schedule,moment * 涉及JS文件:route-->mail.js,public-->js-->capturePart1.js,capturePart2.js,capturePart3.js * 截图保存地址:public-->images-->mainPage.jpeg(1600*4200) * 截图url:http://www.***********.com * 程序主要思路: * (1)phantomjs截图-->参照http://phantomjs.org/ * (2)nodemailer发送邮件-->参照https://www.npmjs.com/package/nodemailer * (3)node-schedule定时-->参照https://www.npmjs.com/package/node-schedule * 注意: * 改变发件服务器请修改SMTP * 改变收件人请修改变量receiver * 改变邮件内容请修改变量html * 改变邮件附加图片和附件请修改attachments * 改变截图功能请修改public-->js-->server.js * 改变定时功能请修改变量rule * ------Sweety ***************************************************************************************************************/ //组件引入开始 var schedule = require("node-schedule");
