电子邮件django的注册无效

Question

我想在Django中通过电子邮件验证实现注册。

1. 运行服务器-

   pyrun =“ python manage.py runserver 127.0.0.1:8001”

2. 填写完整的注册表---确定

3. 已收到带有链接的电子邮件---确定

   http://127.0.0.1/accounts/register/activate/mosk:tQUC9n5kMrmoVSZv4qy6DCAUjaM/

4. 点击链接---收到错误：

   无法访问此站点127.0.0.1拒绝连接

我该如何解决错误？

似乎urls.py可以，我应该在ALLOWED_HOSTS中添加一些内容

Answer 1

通过变更解决了问题

def send_activation_notification(user):
    if ALLOWED_HOSTS:
        #host = "http://" + ALLOWED_HOSTS[0] # BAD VERSION
        host = "http://localhost:8001" # GOOD VERSION FOR ME
    else:
        ...
