Question

我希望根据我的文件类型和文件名模式选择性地应用AWS标头，同时将它们上传到S3源。我正在使用django-storage与django 1.8.12

我可以在django-storages documentation中看到设置AWS_HEADERS，但我似乎无法找到在某些文件上应用此设置的方法。如果有人可以指导我，我将不胜感激

Answer 1

#  handlers.py
import mimetypes
from storages.backends.s3boto import S3BotoStorage
from django.conf import settings

class ManagedS3BotoStorage(S3BotoStorage):
    def _save(self, name, content):
        cleaned_name = self._clean_name(name)
        _type, encoding = mimetypes.guess_type(name)
        content_type = getattr(content, 'content_type',
                               _type or self.key_class.DefaultContentType)
        self.headers.update(self.get_headers(cleaned_name, content_type))
        return super(ManagedS3Storage, self)._save(name, content)

     def get_headers(cleaned_name, content_type):
         // if possible, load AWS_HEADERS_LIST from settings
         headers_list = settings.AWS_HEADERS_LIST
         // logic for updating headers & return headers

settings.py文件中的＃changes

DEFAULT_FILE_STORAGE = 'handlers.ManagedS3BotoStorage'

Answer 2

其他答案大约为S3BotoStorage，此答案大约为S3Boto3Storage（请注意3之后的Boto。您需要覆盖_save_content，如下所示：

class CustomBoto3Storage(S3Boto3Storage):
    def _save_content(self, obj, content, parameters):
        """We want .mp3 files to have the Content-Disposition header set to
        attachement in this example."""

        new_parameters = parameters.copy() if parameters else {}
        if new_parameters.get('ContentType') in ['audio/mpeg3', 'audio/x-mpeg-3', 'audio/mpeg']:
            new_parameters['ContentDisposition'] = 'attachment'
        return super()._save_content(obj, content, new_parameters)

使用django-storage上传静态文件时有选择地应用AWS Headers
