要了解如何设置和运行此示例,请参阅 GitHub

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。

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