Django用户注册、邮箱验证实践

算法流程如下：
1)处理用户注册数据，存入数据库，is_activity字段设置为False，用户未认证之前不允许登陆
2)产生token，生成验证连接URL
3)发送验证邮件
4)用户通过认证邮箱点击验证连接，激活is_activity字段，可以登录
5)若验证连接过期，删除用户在数据库中的注册信息。

#系统root邮箱 settings.py

EMAIL_HOST = ‘smtp.qq.com‘
EMAIL_HOST_USER = ‘17********@qq.com‘
#授权码
EMAIL_HOST_PASSWORD = ‘dxsblqtqohiycgcb‘
EMAIL_PORT = 587
EMAIL_USE_TLS = True
#可以域名，可以设置本地
DOMAIN = ‘http://127.0.0.1:8000‘   

#注册相关路由 url.py

url(r‘^register/$‘, reg, name=‘reg‘),
url(r‘^activate/(?P<token>\w+.[-_\w]*\w+.[-_\w]*\w+)/$‘,     activate,name=‘activate‘),

#注册视图函数 user/views.py

def reg(request):
    try:
        if request.method == ‘POST‘:
            print request.method
            register_form = RegForm(request.POST)
            if register_form.is_valid():
                print ‘数据验证通过！‘
                username=register_form.cleaned_data[‘username‘]
                email=register_form.cleaned_data[‘email‘]

               )
                user.save()
                print ‘注册信息保存成功！‘
                # 邮箱验证
                token = token_confirm.generate_validate_token(username)

                send_mail(u‘注册用户验证信息‘, message, ‘17******@qq.com‘, [email], fail_silently=False)
                return render(request, ‘common/success.html‘, {‘reason‘: u"已将激活链接发送到您的注册邮箱，请登录激活，有效期为1个小时"})
            else:
