我如何使用Python 3在Amazon Linux的EC2上将Django上传的文件存储在S3上？
如果我不能这样做，如果我使用ELB，我该如何在两个EC2实例之间共享上传的文件？
我尝试使用django-storages-py3 + boto#py3kport，但它无法正常工作，当我尝试上传文件时，会出现异常：
string expected bytes given
更新:
以下是我如何使用django-storages-py3 + boto#py3kport:from django.core.files.storage import default_storage
fd = default_storage.open('%s/%s' % ('uploadstg', str(filename)), 'wb')
for chunk in file.chunks():
fd.write(chunk)
fd.close()
fd - S3BotoStorageFile：uploadstg / a6d2532d-34c9-4793-9d43-e9a3e475fc6f.png
文件 - InMemoryUploadedFile：1.png（image / png）
