I edited my bucket policy to add an s3:ListBucket action, but to no avail. When I do so, it just returns a similar message: A client error (AccessDenied) occurred when calling the ListBuckets operation: Access Denied Thoughts? This is also my first time creating an s3 bucket so it's quite possible I missed some important step. I have triple

However, when I inspect my second bucket, there are 40-50 less objects, but I cannot figure out what they are (the directory structure is deeply nested etc). How can I get the file diff of two buckets using aws s3api list-objects ? Perhaps there are files in the bucket which are not videos, which I somehow didn't know about. 回答1: Using Display only filenames : aws s3 ls s3://bucket-1 --recursive |

I found this on one of the AWS docs, but can't complete the command: s3cmd signurl s3://BUCKET/OBJECT <expiry_epoch|+expiry_offset> Any help? 回答1: Did you try aws s3 presign ? Generate a pre-signed URL for an Amazon S3 object. This allows anyone who receives the pre-signed URL to retrieve the S3 object with an HTTP GET request. For sigv4 requests the region needs to be configured explicitly. This

A user can upload a new avatar to my S3 bucket and the avatar shows within the web application. To this end, I've had to grant "AmazonS3FullAccess" policy to the user. That seems like a bit too much, since the user from the application only needs write (upload his avatar) and read (show the avatar on the web page) permission. Would you agree that it is therefore better to write a custom policy rather than use AmazonS3FullAccess? If
