使用 Amazon 软件开发工具包创建 Amazon SNS 主题

以下代码示例显示如何创建 Amazon SNS 主题。

.NET
Amazon SDK for .NET

/// <summary> /// Creates a new SNS topic using the supplied topic name. /// </summary> /// <param name="client">The initialized SNS client object used to /// create the new topic.</param> /// <param name="topicName">A string representing the topic name.</param> /// <returns>The Amazon Resource Name (ARN) of the created topic.</returns> public static async Task<string> CreateSNSTopicAsync(IAmazonSimpleNotificationService client, string topicName) { var request = new CreateTopicRequest { Name = topicName, }; var response = await client.CreateTopicAsync(request); return response.TopicArn; }

C++
SDK for C++

Aws::SDKOptions options; Aws::InitAPI(options); { Aws::String topic_name = argv[1]; Aws::SNS::SNSClient sns; Aws::SNS::Model::CreateTopicRequest ct_req; ct_req.SetName(topic_name); auto ct_out = sns.CreateTopic(ct_req); if (ct_out.IsSuccess()) { std::cout << "Successfully created topic " << topic_name << std::endl; } else { std::cout << "Error creating topic " << topic_name << ":" << ct_out.GetError().GetMessage() << std::endl; } } Aws::ShutdownAPI(options);

Java
SDK for Java 2.x

public static String createSNSTopic(SnsClient snsClient, String topicName ) { CreateTopicResponse result = null; try { CreateTopicRequest request = CreateTopicRequest.builder() .name(topicName) .build(); result = snsClient.createTopic(request); return result.topicArn(); } catch (SnsException e) { System.err.println(e.awsErrorDetails().errorMessage()); System.exit(1); } return ""; }

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 {CreateTopicCommand } from "@aws-sdk/client-sns"; import {snsClient } from "./libs/snsClient.js"; // Set the parameters const params = { Name: "TOPIC_NAME" }; //TOPIC_NAME const run = async () => { try { const data = await snsClient.send(new CreateTopicCommand(params)); console.log("Success.", data); return data; // For unit tests. } catch (err) { console.log("Error", err.stack); } }; run();
