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:UsersaaaDesktopMultipart.html" />
    </Emailcomment>
    <!-- 邮件附件：支持多个 -->
    <EmailAttach>
        <attach file="C:UsersaaaDesktopMultipart.html" />
    </EmailAttach>
</Email>

这个东西这里只用来了解，没有详细学习；有问题可以参考下列文章：

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；
