您正在通过 HTTPS 访问开发服务器，但它仅支持 HTTP。代码 400，消息错误请求语法

Question

我刚开始学习Django框架，我尝试在DigitalOcean的服务器上部署我的第一个项目。如果我运行

python3 manage.py runserver 0.0.0.0:8000

服务器启动。然而，一旦我尝试从(my-rent-ip):8000访问它，我得到这个:

[25/Aug/2021 01:49:01] code 400, message Bad request syntax ('x16x03x01x02x00x01x00x01üx03x03GÛî}زx921x0ex94x17x9cÏe¹x88ñÿÃx16x01éÖRÝx00x95Fx8aGtÉ 8¯,úÂx93´ùx06Ýx14¾zx13Âe4[x9a,.æx96+$<~x8eq<´tx00"ZZx13x01x13x02x13x03À+À/À,À0̨̩Àx13Àx14x00x9cx00x9dx00/x005x00')

[25/Aug/2021 01:49:01] You're accessing the development server over HTTPS, but it only supports HTTP

如果我运行生产服务器，而不是开发服务器，这怎么可能?

我可能做了一些错误的setting.py，因为它必须改变很多生产目的。我做了一个生产分支，改变了settings.py文件，并使用GitHub克隆到服务器。

非常感谢!

Answer 1

您的服务器不支持https，所以设置这些设置:

SECURE_SSL_REDIRECT=False
SESSION_COOKIE_SECURE=False
CSRF_COOKIE_SECURE=False

现在可能需要清除浏览器的缓存并重新启动服务器。错误消息指的是开发服务器，因为python3 manage.py runserver仅用于开发。请注意，您应该在您的生产服务器中设置https(当您将设置https设置再次设置我们之前更改为True的设置时)，并且设置ALLOWED_HOSTS =['*']是一个安全问题。

Answer 2

Use http instead of https in url

我遇到了同样的问题，我可以在ec2 ubuntu 20.04上使用http访问它

在settings.py中使用ALLOWED_HOSTS = ['*' ,'18.11.22.58']

确保您更改了ec2security group and allow traffic to port 8000

像这样运行服务器python3 manage.py runserver 0.0.0.0:8000

尝试以http://18.11.22.58:8000/(不是https)访问您的站点
