说明： 我们常常会用到一些发送邮件的功能，尽管Python已经提供了相对易用的邮件发送模块smtplib。但Django仍对其做了轻度的封装。封装后的模块EmailMultiAlternatives不仅发送邮件速度快，而且在开发环境下也很容易对邮件发送进行测试。下面我们看一下如何实现。

步骤：

1. 去对应的邮箱网站获取邮箱授权码

2. 在Django项目的settings.py中设置

   EMAIL_HOST = "smtp.qq.com"
   EMAIL_PORT = 465 # ssl协议端口号
   EMAIL_HOST_USER = "742323587@qq.com"
   EMAIL_HOST_PASSWORD = "授权密码"
   EMAIL_USE_SSL = True # 是否使用安全套接字层，一般都是True
   EMAIL_FROM = EMAIL_HOST_USER

3. 在views.py里编写视图

   from smtplib import SMTPRecipientsRefused
   from django.core.mail import EmailMultiAlternatives
   msg = EmailMultiAlternatives(subject, html_content, EMAIL_FROM, [to_email])
   msg.attach_alternative(html_content, "text/html")
   try:
       msg.send()
   except SMTPRecipientsRefused as e:
       print(str(e))

   如果你不想把邮箱设置写死在settings.py中，你还可以这样写：

   from smtplib import SMTPRecipientsRefused
   from django.core.mail import EmailMultiAlternatives, get_connection
   msg_list = []
   msg = EmailMultiAlternatives(subject, html_content, EMAIL_FROM, [to_email])
   msg.attach_alternative(html_content, "text/html")
   msg_list.append(msg)
   conn = get_connection()
   conn.username = EMAIL_HOST_USER
   conn.password = EMAIL_HOST_PASSWORD
   conn.port = EMAIL_PORT
   conn.host = EMAIL_HOST
   conn.use_ssl = EMAIL_USE_SSL
   try:
       conn.send_messages(msg_list)
   except SMTPRecipientsRefused as e:
       print(str(e))
   conn.close()

总结： 如果不报错就表示发送成功了，可以打开邮箱看一下！
