import ( "github.com/aws/aws-sdk-go/aws/request" "github.com/aws/aws-sdk-go/service/s3" ) func main() { svc := s3.New(session.New()) _, err := svc.GetObject(&s3.GetObjectInput{ Bucket: aws.String("myBucket"), Key: aws.String(""), // Key parameter is empty, which is an invalid input }) if err != nil { if aerr, ok := err.(request.ErrInvalidParams); ok { // Handle ErrInvalidParams fmt.Println("Invalid input parameter:", aerr) } else { // Handle other errors fmt.Println("Error:", err) } } }In this example, we are trying to get an object from an S3 bucket with an empty Key parameter. This will generate an ErrInvalidParams error because an empty Key is an invalid input. We can handle this error by checking if the error has the ErrInvalidParams type, and then handle it accordingly.
