python练习--发送html格式邮件且发送附件；
最近需要些一个根据配置自动获取html正文及附件的工具脚本。随业余时间写了这个脚本，同时也是对邮件结构的一个学习；后续还需要继续完善html内容生成的部分
感觉脚本还可以优化，比如可以加入图片部分，pdf等，另外发送邮件用的默认铭文方式。没有采用加密/SSL等其他方式；
另外xml配置部分的提取还可以使用字典来做。这样可以更优一些；
代码：
xml配置文件：
<?xml version="1.0" encoding="UTF-8"?><Email> <EmailServerConf> <!-- smtp配置 ：只支持1个--> <smtp ip="email ip" port="25" user="abc" password="defdd" /> </EmailServerConf> <!-- 发件人：只支持1个 --> <From address="abc@123.com" /> <!-- 收件人：支持多个 --> <ToEmailList> <To address="abc@123.com" /> </ToEmailList> <!-- 抄送：支持多个 --> <CCEmailList> <CC address="abc@123.com" /> </CCEmailList> <!-- 邮件主题：只支持1个 --> <Subject title="This is for test!" /> <!-- 邮件正文：只支持1个，html格式，无图片 --> <Emailcomment> <comment file="C:\Users\aaa\Desktop\Multipart.html" /> </Emailcomment> <!-- 邮件附件：支持多个 --> <EmailAttach> <attach file="C:\Users\aaa\Desktop\Multipart.html" /> </EmailAttach></Email>

邮件结构简述：
a、邮件结构可以通过查看邮件源码看到。可以看到邮件其实也是类似http请求一样。有包头，body等；在python中的对应类和方法大多数也是采用hash字典来操作；
b、python中各MIME类的继承结构：
MIMEBase
|-- MIMENonMultipart
|-- MIMEApplication
|-- MIMEAudio
|-- MIMEImage
|-- MIMEMessage
|-- MIMEText
|-- MIMEMultipart
c、各种多媒体格式可以通过MIMEBse类来构造。在头部加入application/octet-stream ，即2进制文件。其实就是MIMEApplication类，让客户端自己根据附件的扩展名判断需要用什么来解析；
