Hi

Is there any way to remove X-Amz-Content-Sha256=UNSIGNED-PAYLOAD while generating presigned url using php. Below is the script. My Target S3 not support header X-Amz-Content-Sha256=UNSIGNED-PAYLOAD and produce error "A header you provided implies functionality that is not implemented."

"latest", "region" => "us-east-1", "signature_version" => "v4", "endpoint" => $endpoint, "use_path_style_endpoint" => true, "credentials" => [ "key" => "xx", "secret" => "xx", ], ]); $key = "image.jpeg"; ## update // Get a command object from the client $command = $s3->getCommand('GetObject', [ 'Bucket' => $bucket, 'Key' => $key ]); // Create a pre-signed URL for a request with duration of 10 miniutes $request = $s3->createPresignedRequest($command, '+10 minutes'); $presignedRequest = $s3->createPresignedRequest($command, '+10 minutes'); // Get the actual presigned-url $presignedUrl = (string) $presignedRequest->getUri(); var_dump($presignedUrl);

Solved. by edit S3SignatureV4.php

and remove/comment this line

// $request = $request->withHeader(
// 'X-Amz-Content-Sha256',
// $this->getPresignedPayload($request)
// );
