使用 Amazon 软件开发工具包删除 Amazon SNS 订阅

以下代码示例显示如何删除 Amazon SNS 订阅。

C++
SDK for C++

Aws::SDKOptions options; Aws::InitAPI(options); { Aws::SNS::SNSClient sns; Aws::String subscription_arn = argv[1]; Aws::SNS::Model::UnsubscribeRequest s_req; s_req.SetSubscriptionArn(subscription_arn); auto s_out = sns.Unsubscribe(s_req); if (s_out.IsSuccess()) { std::cout << "Unsubscribed successfully " << std::endl; } else { std::cout << "Error while unsubscribing " << s_out.GetError().GetMessage() << std::endl; } } Aws::ShutdownAPI(options);

Java
SDK for Java 2.x

public static void unSub(SnsClient snsClient, String subscriptionArn) { try { UnsubscribeRequest request = UnsubscribeRequest.builder() .subscriptionArn(subscriptionArn) .build(); UnsubscribeResponse result = snsClient.unsubscribe(request); System.out.println("\n\nStatus was " + result.sdkHttpResponse().statusCode() + "\n\nSubscription was removed for " + request.subscriptionArn()); } 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。

// Import required AWS SDK clients and commands for Node.js import {UnsubscribeCommand } from "@aws-sdk/client-sns"; import {snsClient } from "./libs/snsClient.js"; // Set the parameters const params = { SubscriptionArn: "TOPIC_SUBSCRIPTION_ARN" }; //TOPIC_SUBSCRIPTION_ARN const run = async () => { try { const data = await snsClient.send(new UnsubscribeCommand(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 subscription to an Amazon SNS topic. * * 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' ]); $subscription = 'arn:aws:sns:us-east-1:111122223333:MySubscription'; try { $result = $SnSclient->unsubscribe([ 'SubscriptionArn' => $subscription, ]); var_dump($result); } catch (AwsException $e) { // output error message if fails error_log($e->getMessage()); }
Python
SDK for Python (Boto3)

class SnsWrapper: """Encapsulates Amazon SNS topic and subscription functions.""" def __init__(self, sns_resource): """ :param sns_resource: A Boto3 Amazon SNS resource. """ self.sns_resource = sns_resource def delete_subscription(subscription): """ Unsubscribes and deletes a subscription. """ try: subscription.delete() logger.info("Deleted subscription %s.", subscription.arn) except ClientError: logger.exception("Couldn't delete subscription %s.", subscription.arn) raise
