Question

我用Django编写了一个应用程序，该应用程序提供使用Webpack构建的文件。该应用程序可以在http上正常运行，但是在https上却出现错误，我似乎找不到解决方法。

将调试设置为True时（例如）

GET https://localhost:8000/dist/bundles/css/main.f57231b6.css net::ERR_ABORTED 404 (Not Found)

将debug设置为false我得到

GET https://localhost:8000/dist/bundles/css/main.f57231b6.css net::ERR_ABORTED 500 (Internal Server Error)

用于CSS和JavaScript。服务器上的回溯看起来像这样：

File "/Applications/anaconda3/lib/python3.6/wsgiref/handlers.py", line 137, in run self.result = application(self.environ, self.start_response) File "/Users/home/docs/Projects/Apprentice_Project/aws_env/lib/python3.6/site-packages/django/contrib/staticfiles/handlers.py", line 67, in __call__ return super().__call__(environ, start_response) File "/Users/home/docs/Projects/Apprentice_Project/aws_env/lib/python3.6/site-packages/django/core/handlers/wsgi.py", line 146, in __call__ response = self.get_response(request) File "/Users/home/docs/Projects/Apprentice_Project/aws_env/lib/python3.6/site-packages/django/contrib/staticfiles/handlers.py", line 62, in get_response return super().get_response(request) File "/Users/home/docs/Projects/Apprentice_Project/aws_env/lib/python3.6/site-packages/django/core/handlers/base.py", line 81, in get_response response = self._middleware_chain(request) TypeError: 'NoneType' object is not callable [01/Aug/2018 05:48:59] "GET /dist/bundles/css/main.f57231b6.css HTTP/1.1" 500 59

谁能告诉我为什么我的https出现NoneType错误？

Answer 1

我认为：关闭调试功能后，Django将不再为您处理静态文件-您的生产Web服务器（Apache或django-whitenoise）应注意这一点希望对您有所帮助：）

通过http提供的静态资源不会通过https提供
