使用带有 Compressor 的 Boto 的 Django AWS S3 无法压缩 UncompressableFileError

Question

在 this guide, and these [1] [2] 帖子之后，我尝试使用 django-storages Boto 在 AWS S3 上设置静态存储。

执行collectstatic时，命令成功收集到STATIC_ROOT。但是，文件没有上传到 S3 压缩，服务器无法提供它们。返回 500 错误。查看日志：

错误信息：

UncompressableFileError: 'https://<myapp>.s3.amazonaws.com/static/oscar/css/styles.css' could not be found in the COMPRESS_ROOT '/var/www/<myappname>/static' or with staticfiles.

编辑：

我也把STATIC_URL改成了http://%s/ % AWS_S3_CUSTOM_DOMAIN，我得到了同样的错误，只是它仍然在https搜索，但是COMPRESS_URL是http.

UncompressableFileError: 'https://<myappname>.s3.amazonaws.com/static/oscar/css/styles.css' isn't accessible via COMPRESS_URL ('http://<myappname>.s3.amazonaws.com/') and can't be compressed

这是否与压缩器和 Boto 不兼容？

相关代码：

# settings/prod.py

AWS_ACCESS_KEY_ID = <Key_ID>
AWS_SECRET_ACCESS_KEY = <Secret_Key>
AWS_STORAGE_BUCKET_NAME = "<my_bucket_name>"
AWS_S3_CUSTOM_DOMAIN = "%s.s3.amazonaws.com" % AWS_STORAGE_BUCKET_NAME
STATIC_URL = "https://%s/" % AWS_S3_CUSTOM_DOMAIN
AWS_LOCATION = 'static'

DEFAULT_FILE_STORAGE = "storages.backends.s3boto.S3BotoStorage"
STATICFILES_STORAGE = "myapp.storage.s3utils.CachedS3BotoStorage"

COMPRESS_STORAGE = "myapp.storage.s3utils.CachedS3BotoStorage"
AWS_IS_GZIPPED = True
COMPRESS_URL = STATIC_URL
STATIC_ROOT = "/var/www/<myappname>/static/"
COMPRESS_ROOT = STATIC_ROOT

storage/s3utils.py 来自 this documentation

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

Answer 1

看来有人遇到了同样的问题：https://github.com/django-compressor/django-compressor/issues/368#issuecomment-182817810

试试这个：

import copy

def save(self, name, content):
    content2 = copy.copy(content)
    name = super(CachedS3BotoStorage, self).save(name, content)
    self.local_storage._save(name, content2)
    return name

注意：我一起使用 django-storages S3BotoStorage 和 django-compressor 没有问题。我认为是 gzipping 导致了问题。

通过这些设置解决：

AWS_ACCESS_KEY_ID = '<KEY_ID>'
AWS_SECRET_ACCESS_KEY = '<SECRET_KEY>'
AWS_STORAGE_BUCKET_NAME = "<app_name>"
AWS_S3_CUSTOM_DOMAIN = "s3.amazonaws.com/%s" % AWS_STORAGE_BUCKET_NAME

MEDIA_URL = "https://%s/media/" % AWS_S3_CUSTOM_DOMAIN
STATIC_URL = "https://%s/static/" % AWS_S3_CUSTOM_DOMAIN
COMPRESS_URL = STATIC_URL

DEFAULT_FILE_STORAGE = '<app_name>.storage.s3utils.MediaS3BotoStorage'
STATICFILES_STORAGE = '<app_name>.storage.s3utils.CachedS3BotoStorage'
COMPRESS_STORAGE = '<app_name>.storage.s3utils.CachedS3BotoStorage'


MEDIA_ROOT = '<app_name>/media/'
STATIC_ROOT = '<app_name>/static/'
COMPRESS_ROOT = STATIC_ROOT


COMPRESS_ENABLED = True
COMPRESS_CSS_FILTERS = ['compressor.filters.css_default.CssAbsoluteFilter',
                        'compressor.filters.cssmin.CSSMinFilter'
                       ]
COMPRESS_PARSER = 'compressor.parser.HtmlParser'

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'compressor.finders.CompressorFinder'
)

和我的s3utils.py

class CachedS3BotoStorage(S3BotoStorage):
    """
    S3 storage backend that saves files locally too. 
    """
    location = 'static'
    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



class MediaS3BotoStorage(S3BotoStorage):
    """ S3 storage backend that saves to the 'media' subdirectory"""
    location = 'media'
