Django项目的设置文件DEBUG = False [关闭]

Question

Django 项目设置文件，DEBUG= False

主要思想是隐藏项目的一些附加重要信息，如环境变量信息、托管信息、静态文件信息等等。

如果我们在生产中使用 DEBUG= True，那么我们可以看到很多项目信息使用浏览器，例如有时我们使用 MVC 模式创建应用程序，如果我们得到错误然后我们可以看到使用浏览器的最大错误。

让我们看看这里设置我的文件 DEBUG 部分并设置 DEBUG=True

Django version 3.2.4, using settings 'school.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

启动服务器后，如果我们在没有 /admin 的情况下路由任何类型的路由，则会出现错误，我们可以从浏览器中看到此错误

在这里查看错误

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/hhh
Using the URLconf defined in school.urls, Django tried these URL patterns, in this order:

admin/
The current path, hhh, didn’t match any of these.

You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

像这个错误一样，我们可以从浏览器中看到很多错误，这对项目非常有害

**所以解决方案是：** 我们必须写 DEBUG=False 并且没有人可以看到这种错误或其他项目的东西

如果我们使用 DEBUG= False 那么我们将面临项目中的一些其他问题，例如修复错误，设置一些其他信息但是如果我们清楚地了解Django settingsfile 那么一切都会非常在我们面前清晰。

谢谢@所有人

Answer 1

在设置中检查INSTALLED_APPS：

...
'django.contrib.staticfiles',
...

还有：

STATIC_URL = '/static/'

还有：

STATIC_ROOT = os.path.join(BASE_DIR, 'static')

如果这没有帮助，请显示完整的 settings.py 文件。
