使用 Amazon 软件开发工具包删除 Amazon SNS 主题

以下代码示例显示如何删除 Amazon SNS 主题以及该主题的所有订阅。

.NET
Amazon SDK for .NET

/// <summary> /// This example deletes an existing Amazon Simple Notification Service /// (Amazon SNS) topic. The example was created using the AWS SDK for .NET /// version 3.7 and .NET Core 5.0. /// </summary> public class DeleteSNSTopic { public static async Task Main() { string topicArn = "arn:aws:sns:us-east-2:704825161248:ExampleSNSTopic"; IAmazonSimpleNotificationService client = new AmazonSimpleNotificationServiceClient(); var response = await client.DeleteTopicAsync(topicArn); } }

C++
SDK for C++

Aws::SDKOptions options; Aws::InitAPI(options); { Aws::String topic_arn = argv[1]; Aws::SNS::SNSClient sns; Aws::SNS::Model::DeleteTopicRequest dt_req; dt_req.SetTopicArn(topic_arn); auto dt_out = sns.DeleteTopic(dt_req); if (dt_out.IsSuccess()) { std::cout << "Successfully deleted topic " << topic_arn << std::endl; } else { std::cout << "Error deleting topic " << topic_arn << ":" << dt_out.GetError().GetMessage() << std::endl; } } Aws::ShutdownAPI(options);

Java
SDK for Java 2.x

public static void deleteSNSTopic(SnsClient snsClient, String topicArn ) { try { DeleteTopicRequest request = DeleteTopicRequest.builder() .topicArn(topicArn) .build(); DeleteTopicResponse result = snsClient.deleteTopic(request); System.out.println("\n\nStatus was " + result.sdkHttpResponse().statusCode()); } catch (SnsException e) { System.err.println(e.awsErrorDetails().errorMessage()); System.exit(1); } }

JavaScript
SDK for JavaScript V3

在单独的模块中创建客户端并将其导出。

import { SNSClient } from "@aws-sdk/client-sns"; // Set the AWS Region. const REGION = "REGION"; //e.g. "us-east-1" // Create SNS service object. const snsClient = new SNSClient({ region: REGION }); export { snsClient };

导入开发工具包和客户端模块,然后调用 API。

// Load the AWS SDK for Node.js // Import required AWS SDK clients and commands for Node.js import {DeleteTopicCommand } from "@aws-sdk/client-sns"; import {snsClient } from "./libs/snsClient.js"; // Set the parameters const params = { TopicArn: "TOPIC_ARN" }; //TOPIC_ARN const run = async () => { try { const data = await snsClient.send(new DeleteTopicCommand(params)); console.log("Success.", data); return data; // For unit tests. } catch (err) { console.log("Error", err.stack); } }; run();
PHP
SDK for PHP

require 'vendor/autoload.php'; use Aws\Sns\SnsClient; use Aws\Exception\AwsException; /** * Deletes a SNS topic and all its subscriptions. * * This code expects that you have AWS credentials set up per: * https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/guide_credentials.html */ $SnSclient = new SnsClient([ 'profile' => 'default', 'region' => 'us-east-1', 'version' => '2010-03-31' ]); $topic = 'arn:aws:sns:us-east-1:111122223333:MyTopic'; try { $result = $SnSclient->deleteTopic([ 'TopicArn' => $topic, ]); var_dump($result); } catch (AwsException $e) { // output error message if fails error_log($e->getMessage()); }
