AWS SDK for Go code examples for Amazon SNS

Purpose

These examples demonstrate how to perform several Amazon Simple Notification Service (Amazon SNS) operations.

Prerequisites

You must have an AWS account, and have your default credentials and AWS Region configured as described in Configuring the AWS SDK for Go in the AWS SDK for Go Developer Guide.

Running the code

MakeTopic/MakeTopic.go

This example creates an Amazon SNS topic.

go run MakeTopic.go -t TOPIC

• TOPIC is the name of the topic to create.

The unit test mocks the service client and the CreateTopic function.

PublishMessage/PublishMessage.go

This example publishes a message to an Amazon SNS topic.

go run PublishMessage.go -m MESSAGE -t TOPIC-ARN

• MESSAGE is the message to publish.
• TOPIC-ARN is the Amazon Resource Name (ARN) of the topic to which the user subscribes.

The unit test mocks the service client and the Publish function.

ShowSubscriptions/ShowSubscriptions.go

This example displays the Amazon Resource Names (ARNs) of your Amazon SNS subscriptions.

go run ShowSubscriptions.go

The unit test mocks the service client and the ListSubscriptions function.

ShowTopics/ShowTopics.go

This example displays the Amazon Resource Names (ARNs) of your Amazon SNS topics.

go run ShowTopics.go

The unit test mocks the service client and the ListTopics function.

SubscribeTopic/SubscribeTopic.go

This example subscribes a user to a topic by their email address.

go run SubscribeTopic.go -e EMAIL -t TOPIC-ARN

• EMAIL is the email address of the user.
• TOPIC-ARN is the Amazon Resource Name (ARN) of the topic.

The unit test mocks the service client and the Subscribe function.

Notes

• We recommend that you grant this code least privilege, or at most the minimum permissions required to perform the task. For more information, see Grant Least Privilege in the AWS Identity and Access Management User Guide.
• This code has not been tested in all AWS Regions. Some AWS services are available only in specific Regions.
• Running this code might result in charges to your AWS account.

Running the unit tests

Unit tests should delete any resources they create. However, they might result in charges to your AWS account.

To run a unit test, enter the following.

go test

You should see something like the following, where PATH is the path to the folder containing the Go files.

PASS
ok      PATH 6.593s

To see any log messages, enter the following.

go test -test.v

You should see additional log messages. The last two lines should be similar to the previous output shown.
