我想用dropbox來使用django-storage。 我所做的一切都像在文檔：Django Dropbox存儲
set DEFAULT_FILE_STORAGE = 'storages.backends.dropbox.DropBoxStorage',
DROPBOX_OAUTH2_TOKEN = 'MY_ACCESS_TOKEN'
DROPBOX_ROOT_PATH = 'media'
但是，當我試圖在Heroku上上傳圖片，我得到了在日誌中的錯誤：
TypeError: expected request_binary as binary type, got
class'django.core.files.uploadedfile.InMemoryUploadedFile'
完全回溯：
