如何使用 django_compressor 将压缩文件发送到 Amazon S3？

我尝试了几种方法，但没有奏效。这是我最后的 settings.py 配置：

COMPRESS_ENABLED = True
COMPRESS_OFFLINE = True

COMPRESS_ROOT = STATIC_ROOT
COMPRESS_URL = "http://xxx.cloudfront.net/"
STATIC_URL = COMPRESS_URL
COMPRESS_OUTPUT_DIR = 'CACHE'

#COMPRESS_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
COMPRESS_STORAGE = 'core.storage.CachedS3BotoStorage'

STATICFILES_STORAGE = 'compressor.storage.GzipCompressorFileStorage'
COMPRESS_YUI_BINARY = 'java -jar contrib/yuicompressor-2.4.7/build/yuicompressor-2.4.7.jar'
COMPRESS_YUI_JS_ARGUMENTS = ''
COMPRESS_CSS_FILTERS = ['compressor.filters.yui.YUICSSFilter']
COMPRESS_JS_FILTERS = ['compressor.filters.yui.YUIJSFilter']
COMPRESS_CSS_HASHING_METHOD = 'hash'

和我的storage.py

from django.core.files.storage import get_storage_class
from storages.backends.s3boto import S3BotoStorage

class CachedS3BotoStorage(S3BotoStorage):
    """
    S3 storage backend that saves the files locally, too.
    """
    def __init__(self, *args, **kwargs):
        super(CachedS3BotoStorage, self).__init__(*args, **kwargs)
        self.local_storage = get_storage_class(
            "compressor.storage.CompressorFileStorage")()

    def save(self, name, content):
        name = super(CachedS3BotoStorage, self).save(name, content)
        self.local_storage._save(name, content)
        return name

django-storages S3 存储后端支持 gzip。添加到settings.py：

AWS_IS_GZIPPED = True

经过几天的努力和研究，我终于能够做到这一点。

基本上你需要做几件事：

  1. 利用AWS_IS_GZIPPED = True
  2. 如果您的 S3 在美国境外。您需要创建一个自定义S3Connection类，在其中将DefaultHost变量覆盖到您的 S3 url。例子s3-eu-west-1.amazonaws.com
  3. 如果您使用虚线存储桶名称，例如subdomain.domain.tld. 你需要设置AWS_S3_CALLING_FORMAT = 'boto.s3.connection.OrdinaryCallingFormat'
  4. 你必须non_gzipped_file_content = content.file在你的CachedS3BotoStorage

这是CachedS3BotoStorage您需要的课程：

class CachedS3BotoStorage(S3BotoStorage):
    """
    S3 storage backend that saves the files locally, too.

    """
    connection_class = EUConnection
    location = settings.STATICFILES_LOCATION

    def __init__(self, *args, **kwargs):
        super(CachedS3BotoStorage, self).__init__(*args, **kwargs)
        self.local_storage = get_storage_class(
            "compressor.storage.CompressorFileStorage")()

    def save(self, name, content):
        non_gzipped_file_content = content.file
        name = super(CachedS3BotoStorage, self).save(name, content)
        content.file = non_gzipped_file_content
        self.local_storage._save(name, content)
        return name

2019 年更新：官方文档中有描述

#mysite.py
from django.core.files.storage import get_storage_class
from storages.backends.s3boto import S3BotoStorage

class CachedS3BotoStorage(S3BotoStorage):
    """
    S3 storage backend that saves the files locally, too.
    """
    def __init__(self, *args, **kwargs):
        super(CachedS3BotoStorage, self).__init__(*args, **kwargs)
        self.local_storage = get_storage_class(
            "compressor.storage.CompressorFileStorage")()

    def save(self, name, content):
        self.local_storage._save(name, content)
        super(CachedS3BotoStorage, self).save(name, self.local_storage._open(name))
        return name

和你的设置：

#settings.py
INSTALLED_APPS += ['compressor']

AWS_IS_GZIPPED = True

STATIC_ROOT = '/path/to/staticfiles' #if not set, set this to an empty folder
COMPRESS_ROOT = STATIC_ROOT
STATICFILES_STORAGE = 'mysite.storage.CachedS3BotoStorage'
COMPRESS_STORAGE = STATICFILES_STORAGE
STATIC_URL = 'https://compressor-test.s3.amazonaws.com/'
COMPRESS_URL = STATIC_URL

你可以简单地运行：

python manage.py collectstatic
