Python Django中QQ邮箱授权码问题

系统及软件版本如下：

• Ubuntu Kylin 16.04
• Python 3.5.1
• Django 1.9.7
• PyCharm Community Edition 2016.1.4

问题

在学习用Django写一个博客的过程中，需添加一个邮件分享功能，在使用QQ邮箱发送邮件的时候碰到了问题。

在设置文件settings.py中添加以下设置:

EMAIL_HOST = 'smtp.qq.com'

EMAIL_HOST_USER = '2460490819@qq.com'

EMAIL_HOST_PASSWORD = 'password'

EMAIL_PORT = 587

EMAIL_USE_TLS = True

使用manage.py提供的shell工具进行测试：

panzeyan@panzeyan-S400CA:~/PycharmProjects/myDjangoProject/mysite$ python3 manage.py shell

Python 3.5.1+ (default, Mar 30 2016, 22:46:26)

Type "help", "copyright", "credits" or "license" for more information.

>>> from django.core.mail import send_mail

>>> send_mail("learn django", "step by step", "2460490819@qq.com",['2460490819@qq.com'], fail_silently=False)

抛出异常：

Traceback (most recent call last):

ImportError

During handling of the above exception, another exception occurred:

思路和解决方法

忽略ImportError，关注SMTPAuthenticationError。猜测是QQ邮箱SMTP服务的授权问题导致发送邮件失败。

打开异常末尾给出的链接：

http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

QQ邮箱需使用授权码作为专用密码，登录第三方客户端，所以用原来的密码会导致错误。

按照链接中的提示，进入QQ邮箱设置页面，开启SMTP服务，发短信获取授权码。然后在settings.py中将16位授权码赋值给EMAIL_HOST_PASSWORD。

EMAIL_HOST_PASSWORD = 'shlvewmsheooebhd'

进入manage.py提供的shell工具进行测试：

>>> from django.core.mail import send_mail

>>> send_mail("1", "2", "2460490819@qq.com", ['2460490819@qq.com'], fail_silently=False)

1

1表示发送成功。登录邮箱，成功收到邮件，问题解决。
