Can a URL be directly uploaded to S3 using POST

Question

I wish to upload to S3 directly using POST without the files going to backend server. Is there a way to do it with URL?

Consider this example, upload a file that resides at xyz link to S3 using post.

Answer 1

Go ahead and modify your buckets' security settings in some fashion to allow this type of interaction. Check this out for reference

Not using public keys may cause certain security issues

Answer 2

Your question sounds like you want S3 itself to download the file from a remote server where you only pass the URL of the resource to S3.

This is not currently supported by S3.

It needs an API client to actually transfer the content of the object to S3.

Answer 3

S3 can accept a file uploaded from a server, but the server must initiate the upload to S3 and transfer the contents (thus becoming a client of S3). S3 cannot initiate the transfer from a another web server given a URL. Your server will need to download the file from the URL and then upload it to S3.
