/// <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); } }

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 };
导入软件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();
