How to upload a file to S3 and make it public using boto3?
提问by Adi
I am able to upload an image file using:
我可以使用以下方法上传图像文件：
s3 = session.resource('s3')
bucket = s3.Bucket(S3_BUCKET)
bucket.upload_file(file, key)
However, I want to make the file public too. I tried looking up for some functions to set ACL for the file but seems like boto3 have changes their API and removed some functions. Is there a way to do it in the latest release of boto3?
但是，我也想公开该文件。我尝试查找一些函数来为文件设置 ACL，但似乎 boto3 已经更改了它们的 API 并删除了一些函数。有没有办法在最新版本的 boto3 中做到这一点？

I was able to do it using objectAcl API:
我能够使用 objectAcl API 做到这一点：
s3 = boto3.resource('s3')
object_acl = s3.ObjectAcl('bucket_name','object_key')
response = object_acl.put(ACL='public-read')

To upload and set permission to publicly-readable in one step, you can use:
一步上传并设置公开可读权限，您可以使用：
bucket.upload_file(file, key, ExtraArgs={'ACL':'public-read'})
bucket.upload_file(file, key, ExtraArgs={'ACL':'public-read'})

Adi's wayworks. However, if you were like me, you might have run into an access denied issue. This is normally caused by broken permissions of the user.
I fixed it by adding the following to the Actionarray:
阿迪的方法奏效了。但是，如果您像我一样，可能会遇到拒绝访问的问题。这通常是由用户权限损坏引起的。我通过将以下内容添加到Action数组中来修复它：
"s3:GetObjectAcl",
"s3:PutObjectAcl"
