DeleteTopic与 Amazon SDK 或 CLI 配合使用

按主题 ARN 删除主题。

删除 SNS 主题

以下 delete-topic 示例将删除指定的 SNS 主题。

aws sns delete-topic \
    --topic-arn "arn:aws:sns:us-west-2:123456789012:my-topic"

此命令不生成任何输出。

在单独的模块中创建客户端并将其导出。

import { SNSClient } from "@aws-sdk/client-sns";

// The AWS Region can be provided here using the `region` property. If you leave it blank
// the SDK will default to the region set in your AWS config.
export const snsClient = new SNSClient({});

导入 SDK 和客户端模块，然后调用 API。

import { DeleteTopicCommand } from "@aws-sdk/client-sns";
import { snsClient } from "../libs/snsClient.js";

/**
 * @param {string} topicArn - The ARN of the topic to delete.
 */
export const deleteTopic = async (topicArn = "TOPIC_ARN") => {
  const response = await snsClient.send(
    new DeleteTopicCommand({ TopicArn: topicArn }),
  );
  console.log(response);
  // {
  //   '$metadata': {
