python发送带有附件的163邮件
问题背景
在开发私人公众号，根据开发公众号的初衷需求，需要实现python脚本下发送带有附件的163邮件，实现Kindle电子书的自动化推送。 详细源码
问题解决
第一次尝试
最初的代码，使用web.py框架提供的发送邮件的代码，
web.config.smtp_server = 'smtp.gmail.com'
web.config.smtp_port = 587
web.config.smtp_username = '[email protected]'
web.config.smtp_password = 'secret'
web.config.smtp_starttls = True
# Once this configuration is set, web.sendmail can be used to send mail using the gmail account. Gmail signs all these mails.
web.sendmail('[email protected]', '[email protected]', 'subject', 'message')
但是具体试验不成功，代码路径为：http://webpy.org/cookbook/sendmail_using_gmail
后边发现原因可能在于最终调用到
smtplib.SMTP_SSL(mail_host, port=port)
的差异上，web.py调用的不是上边对应的接口，而是下述代码片段
第二次尝试
既然方案不生效，那么只能找其他方法，开始在网络上一边寻找，一边试验代码是不是生效。哈哈哈，功夫不负有心人，终于还是找到可用的代码，也是通过下边的这段代码确定是接口调用的问题。参考的代码在https://blog.csdn.net/gpf951101/article/details/78909233这篇博客，
完整的代码如下：
import smtplib
from email.mime.text import MIMEText
def send_mail(username, passwd, recv, title, content, mail_host='smtp.163.com', port=465):
msg = MIMEText(content)
msg['Subject'] = title
msg['From'] = username
msg['To'] = recv
print 'Begin Connect...'
smtp = smtplib.SMTP_SSL(mail_host, port=port)
print 'Begin Login...'
smtp.login(username, passwd)
print 'Begin Send...'
smtp.sendmail(username, recv, msg.as_string())
smtp.quit()
print('email send success.')
if __name__ == '__main__':
email_user = '[email protected]'
email_pwd = 'xxxxx'
maillist = '[email protected]'
title = 'mytitle'
content = 'content, I comes from China!'
send_mail(email_user, email_pwd, maillist, title, content)
@gpf951101特别感谢这位作者。上边的代码不是鄙人写的，来自上述链接。
到现在为止实现了python发送163的普通邮件，还差发送附件的功能。
第三次尝试
还是在网络上寻找，最终找到https://github.com/rootzhongfengshan/python_practical/blob/master/SentMail/SentMailWithAttachment.py
于是，最终的代码成型。来之不易，还望对诸君有所帮助。

except Exception, exc:
print exc, traceback.print_exc()
解释代码
- from config import settings
这个文件中用于载入设置文件，因为，邮件的账户和密码是敏感信息，不方便直接放出来，尤其是把自己的代码用GitHub作为Host，这样上传代码的时候可以不用上传配置文件。下边是config.py代码片
import configparser
settings = configparser.ConfigParser()
settings._interpolation = configparser.ExtendedInterpolation()
settings.read('./config.ini')
print settings.sections()
print settings.get(u'email section', 'email user')
对应的config.ini文件如下，删除了敏感信息：
[email section]
email user: ********@163.com
email password: ****
- 突然发现其他的没什么好说的了。
尾声
祝福大家都能写出好代码。
