Sdk v2 migration issue with s3 presigned put request

[maciejbak85]

In my code I did:

sdkReq, err := presignClient.PresignPutObject(conn.ctx, &putInput)
signedHeaders := sdkReq.SignedHeader
log.Default().Println("Print signedHeaders --->")
for key := range signedHeaders {
  value := signedHeaders[key]
  log.Default().Println("key and value ", key, value)
}

in version 1 it showed me:

2023-03-15T14:27:15.255+01:00 2023/03/15 13:27:15 key and value x-amz-server-side-encryption-customer-key [m/91I5....o=] ( dotted this key not sure if its safe to paste whole )

but in V2:
2023-03-15T14:30:47.564+01:00 2023/03/15 13:30:47 key and value X-Amz-Server-Side-Encryption-Customer-Key [��l��6ꐓ�/�����4j�hP��������UOl]

coz of that I have some issues with uploading, how to fix that ?

( btw. frontend takes this url and makes POST request containing:
-H 'x-amz-server-side-encryption-customer-key: , so of course due to those weird chars it does not work )
thanks!

ok nvm I found out:

func encodeCustomerKey(value []string) []string {
	str := strings.Join(value, "")
	strBytes := []byte(str)
	encoded := base64.StdEncoding.EncodeToString(strBytes)
	customeyKeySlice := []string{encoded}
	return customeyKeySlice
}

if key == "X-Amz-Server-Side-Encryption-Customer-Key" {
	signedHeaders["X-Amz-Server-Side-Encryption-Customer-Key"] = encodeCustomerKey(value)
}
