Excellent , this work fine
I attach the final sample code
s3Svc := s3.New(session.New(&aws.Config{Region:
aws.String("us-west-2")}))
result, err := s3Svc.GetObject(&s3.GetObjectInput{
Bucket: aws.String(bucket),
Key: aws.String(key),
})
if err != nil {
fmt.Fprintln(os.Stderr, err)
os.Exit(1)
}
io.Copy(os.Stdout, result.Body)
result.Body.Close()
Thanks so much
