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

Question

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

\n

python3 manage.py runserver 0.0.0.0:8000\n

\n

服务器启动。但是，一旦我尝试从 (my-rent-ip):8000 访问它，我会得到以下信息：

\n

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

\n

如果我运行生产服务器而不是开发服务器，这怎么可能？

\n

我可能做错了什么，setting.py因为出于生产目的必须对其进行大量更改。我创建了一个生产分支，更改了settings.py文件，并使用 GitHub 克隆到服务器。这里是：

太感谢了！

Answer 1

您的服务器不支持 https，因此请设置以下设置：

SECURE_SSL_REDIRECT=False
SESSION_COOKIE_SECURE=False
CSRF_COOKIE_SECURE=False

也许现在您需要清除浏览器的缓存并重新启动服务器。该错误消息指的是开发服务器，因为python3 manage.py runserver仅在开发中使用。请注意，您应该在生产服务器中设置 https（当您设置 https 时，请再次设置我们之前更改为 True 的设置），并且设置 ALLOWED_HOSTS = ['*'] 是一个安全问题。
