Django-Compressor使用amazonaws和heroku在django-storages中抛出UncompressableFileError [英] Django-Compressor throws UncompressableFileError with django-storages using amazonaws and heroku

问题描述

我有问题找到问题的问题。

我有设置文件夹，里面我有local.py，common.py和production.py。所有的工作都很好，它在压缩本地主机，但不是在英雄上。

当我部署它，我得到错误：

 内部服务器错误：/ 
 
 / 
'中的UncompressableFileError https://xxxxx.s3.amazonaws.com/static/css /stylesheet.css'无法通过COMPRESS_URL（'//xxxxx.s3.amazonaws.com/static/'）访问，无法压缩

 S3存储后端也可以在本地保存文件。

解决方案
我花了整整一个晚上尝试解决这个问题，我在这段代码中做了一些改动：
 无法通过COMPRESS_URL（'//xxxxx.s3.amazonaws.com/static/'）访问
  
我以为可以添加http或https，我有
  AWS_S3_SECURE_URLS = True 
  
所以只是为了测试我添加了硬编码的
  https：
  
像这样
  STATIC_URL =https ：//％s /％s /％（AWS_S3_CUSTOM_DOMAIN，STATICFILES_LOCATION）
  
它开始工作，太好了。但是任何人都可以解释为什么不识别或添加http或https？
 
I am having problem to locate the issue of the problem.

I have settings folder and inside I have local.py, common.py and production.py. All is working great and it is compressing on localhost, but not on heroku.

When I deploy it I am getting error:
Internal Server Error: /

UncompressableFileError at /
'https://xxxxx.s3.amazonaws.com/static/css/stylesheet.css' isn't accessible via COMPRESS_URL ('//xxxxx.s3.amazonaws.com/static/') and can't be compressed

解决方案
I spent the whole night trying to solve this and I made a little change in this code:
isn't accessible via COMPRESS_URL ('//xxxxx.s3.amazonaws.com/static/')
I thought it can add http or https and I have 
AWS_S3_SECURE_URLS = True
So just for test I added hardcoded
https:
like this
STATIC_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, STATICFILES_LOCATION)
and it started working, it is great. But can anyone explain why it is not recognizing or adding http or https to it?
