In this video, we are going to be looking at how we can implement a deleteItem function which will allow us to delete items from our S3 bucket and clean up after ourselves:
Deleting Items
Let’s set about implementing this deleteItem function now:
func deleteItem(sess *session.Session) {
svc := s3.New(sess)
input := &s3.DeleteObjectInput{
Bucket: aws.String("go-aws-s3-course"),
Key: aws.String("my-file.txt"),
}
result, err := svc.DeleteObject(input)
if err != nil {
if aerr, ok := err.(awserr.Error); ok {
switch aerr.Code() {
default:
log.Fatal(aerr.Error())
}
} else {
log.Fatal(err.Error())
}
}
log.Printf("Result: %+v\n", result)
}
Let’s also update our main func:
func main() {
fmt.Println("Downloads and Uploads")
sess, err := session.NewSession(&aws.Config{
Region: aws.String("us-west-2"),
})
if err != nil {
log.Fatal("Could not get session")
}
uploadItem(sess)
listItems(sess)
deleteItem(sess)
listItems(sess)
}
Perfect, with this in place, let’s try and run this and see if it deletes our file:
$ go run 04-deleting-items/main.go
