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();

      snsClient.deleteTopic(request)
      println("$topicArnVal was successfully deleted.")
    }
