邮件自动发送程序GUI版

使用场景

当使用者需要群发内容框架一致而只有少许内容不同的邮件时，会因为频繁地修改琐碎的细节而浪费大量时间，这样一来一个可供配置和扩展的自动邮件程序就十分有必要。

比如说我作为课程助教需要发送邮件给每个考试了的同学他的课程成绩，那么邮件中不同的地方就只有接收者的名字、学号以及成绩。

这些信息通常记录在Excel表中，一个自动邮件发送程序应当可以匹配不同的姓名、学号对应的成绩。这样一来，就可以将邮件发送者从繁琐而无意义的体力劳动中解放出来，而且减少了成绩输入错误这种可能情况的发生。

GUI设计版

一个简易的Python写的邮件自动发送程序可以参考我的上一篇文章，介绍了发送邮件的基本框架。

这一次我进一步简化了用户对程序的依赖程度。他只需要运行程序，根据各项文字提示输入必要信息，点击两个按钮即可完成邮件的批量个性化定制发送操作。

首先来看程序源码如下：

运行实例

运行程序初始界面



填写内容完毕



依次点击Upload，Run按钮



注意，点击Run按钮后下方提示文字由“Hello, master!”变成了“Send emails automatically!”。当然也可以替换成其他的文字，只要你找得到我是在代码第多少行写得这个~

邮件是可以发送的，在本地邮箱服务器发件箱中可以查看，但是我测试用的地址估计是收不到的。大家如果使用这个AutoMailor记得把数据最后一列地址列填写成正确的收件邮箱。

导出成可执行文件

有时间我再研究一下将其制作成exe文件的方法。

另外，这个代码考虑的异常情况不够多，如果不按照标准输入操作的话，发送是不会成功的。后面我会继续维护这个一时兴起写的小软件，有兴趣的童鞋可以多交流哈！
