Django amazon s3 SuspiciousOperation

问题

So when i try accessing a certain image on S3 from my browser everything works fine. But when python is doing it i get a SuspiciousOperation error. My static folder is public on S3 so i really have no idea where this is coming from.

Publication.objects.get(id=4039).cover.url
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/vagrant/.pyenv/versions/blook/lib/python2.7/site-packages/django/db/models/fields/files.py", line 64, in _get_url
    return self.storage.url(self.name)
  File "/home/vagrant/.pyenv/versions/blook/lib/python2.7/site-packages/queued_storage/backends.py", line 291, in url
    return self.get_storage(name).url(name)

    name)
SuspiciousOperation: Attempted access to 'http:/s3-eu-west-1.amazonaws.com/xpto/static/images/default-image.png' denied.

My settings:

AWS_S3_SECURE_URLS = True  # use http instead of https
S3_URL = 'http://s3-eu-west-1.amazonaws.com/%s' % AWS_STORAGE_BUCKET_NAME
MEDIA_ROOT = 'media/'
STATIC_ROOT = '/static/'
STATIC_URL = S3_URL + STATIC_ROOT
MEDIA_URL = S3_URL + '/' + MEDIA_ROOT

For now i can work around it, but that is not a long term solution. any ideas?

Danigosa's answer in this thread is the answer: django-storages and amazon s3 - suspiciousoperation

Create a special storage class as outlined in this post: Using Amazon S3 to store your Django sites static and media files.

Then override _normalize_name like this:

from django.conf import settings
from storages.backends.s3boto3 import S3Boto3Storage


class StaticStorage(S3Boto3Storage):

    location = settings.STATICFILES_LOCATION

    def _clean_name(self, name):
        return name

    def _normalize_name(self, name):
        if not name.endswith('/'):
            name += "/"

        name += self.location
        return name


class MediaStorage(S3Boto3Storage):

    location = settings.MEDIAFILES_LOCATION

    def _clean_name(self, name):
        return name

    def _normalize_name(self, name):
        if not name.endswith('/'):
            name += "/"

        name += self.location
        return name

Finally - (on Python 3 at least) DON'T use
