The following example sends the message supplied on the command line to all subscribers to the Amazon SNS topic with the ARN specified on the command line.

package main import ( "" "" "" "flag" "fmt" "os" ) func main() { msgPtr := flag.String("m", "", "The message to send to the subscribed users of the topic") topicPtr := flag.String("t", "", "The ARN of the topic to which the user subscribes") flag.Parse() message := *msgPtr topicArn := *topicPtr if message == "" || topicArn == "" { fmt.Println("You must supply a message and topic ARN") fmt.Println("Usage: go run SnsPublish.go -m MESSAGE -t TOPIC-ARN") os.Exit(1) } // Initialize a session that the SDK will use to load // credentials from the shared credentials file. (~/.aws/credentials). sess := session.Must(session.NewSessionWithOptions(session.Options{ SharedConfigState: session.SharedConfigEnable, })) svc := sns.New(sess) result, err := svc.Publish(&sns.PublishInput{ Message: aws.String(message), TopicArn: topicPtr, }) if err != nil { fmt.Println(err.Error()) os.Exit(1) } fmt.Println(*result.MessageId) }
