Django-compressor：如何写入S3，并从CloudFront读取？

Django-compressor：如何写入S3，并从CloudFront读取？

我围绕boto提供的包装后端编写了一个包装器存储后端

myapp / storage_backends.py：

import urlparsefrom django.conf import settingsfrom storages.backends.s3boto import S3BotoStoragedef domain(url):    return urlparse.urlparse(url).hostnameclass MediaFilesStorage(S3BotoStorage):    def __init__(self, *args, **kwargs):        kwargs['bucket'] = settings.MEDIA_FILES_BUCKET        kwargs['custom_domain'] = domain(settings.MEDIA_URL)        super(MediaFilesStorage, self).__init__(*args, **kwargs)class StaticFilesStorage(S3BotoStorage):    def __init__(self, *args, **kwargs):        kwargs['bucket'] = settings.STATIC_FILES_BUCKET        kwargs['custom_domain'] = domain(settings.STATIC_URL)        super(StaticFilesStorage, self).__init__(*args, **kwargs)

我的settings.py文件所在的位置…

STATIC_FILES_BUCKET = "myappstatic"MEDIA_FILES_BUCKET = "myappmedia"STATIC_URL = "http://XXXXXXXX.cloudfront.net/"MEDIA_URL = "http://XXXXXXXX.cloudfront.net/"DEFAULT_FILE_STORAGE = 'myapp.storage_backends.MediaFilesStorage'COMPRESS_STORAGE = STATICFILES_STORAGE = 'myapp.storage_backends.StaticFilesStorage'
