Question

我正在运行一个将所有静态和媒体文件添加到Amazon S3的Django项目。我使用的是过去曾多次使用过的settings.py配置，可以用于其他多个项目（在下面发布）。

当我在自己的localhost上使用相同的settings.py文件时。我可以正常运行python manage.py collectstatic --noinput，它会将所有静态文件上传到Amazon S3。但是，当我将项目放在Elastic Beanstalk应用程序服务器上并使用相同的设置运行相同的命令时，我得到S3ResponseError: 301 Moved Permanently。

我的设置是：

AWS_STORAGE_BUCKET_NAME = 's3.cupcard.com'
AWS_S3_CUSTOM_DOMAIN = AWS_STORAGE_BUCKET_NAME
AWS_S3_CALLING_FORMAT = 'boto.s3.connection.OrdinaryCallingFormat'
AWS_S3_SECURE_URLS = False
AWS_S3_URL_PROTOCOL = 'http:'  # Replace with 'https:' if you're not using http.

STATICFILES_LOCATION = 'static'
STATIC_URL = "http://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, STATICFILES_LOCATION)
STATICFILES_STORAGE = 'lindshop.utils.custom_storages.CachedS3BotoStorage'

MEDIAFILES_LOCATION = 'media'
MEDIA_URL = "http://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, MEDIAFILES_LOCATION)
DEFAULT_FILE_STORAGE = 'lindshop.utils.custom_storages.MediaStorage'

lindshop.utils.custom_storages.CachedS3BotoStorage看起来像这样：

class EuropeConnection(S3Connection):
    DefaultHost = "s3-eu-west-1.amazonaws.com"

class CachedS3BotoStorage(S3BotoStorage):
    connection_class = EuropeConnection
    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

总结并重复自己。

我可以从localhost运行python manage.py collectstatic。我还验证了我可以使用collectstatic命令访问localhost在那里放置的S3实例上的文件。当我从具有相同设置的Elastic Beanstalk应用程序执行相同操作时，我收到错误。
我之前在其他项目中使用了相同的设置而没有任何问题。唯一改变的是存储桶名称。
我在EB服务器上运行collectstatic时遇到的错误是S3ResponseError: 301 Moved Permanently。

我发现问题是因为我使用的Django模块django-storages的更新。在更新中，他们通过以下方式分配默认值S3BotoStorage.host：

host = setting('AWS_S3_HOST', S3Connection.DefaultHost)

主机会自动设置为s3.amazonaws.com，并且因为它在创建与boto（AWS官方python-package）的连接时已经拥有主机集，所以它永远不会使用{我在DefaultHost = "s3-eu-west-1.amazonaws.com" - 课程中添加了{1}}。

解决此问题的方法是在EuropeConnection中设置django-storages设置值AWS_S3_HOST（新建）。

settings.py

Django在S3ResponseError中的collectstatic结果：301永久移动
