使用 Amazon 软件开发工具包设置 Amazon SNS 主题属性

    public static void setTopAttr(SnsClient snsClient, String attribute, String topicArn, String value) {

        try {

            SetTopicAttributesRequest request = SetTopicAttributesRequest.builder()
                .attributeName(attribute)
                .attributeValue(value)
                .topicArn(topicArn)
                .build();

            SetTopicAttributesResponse result = snsClient.setTopicAttributes(request);
            System.out.println("\n\nStatus was " + result.sdkHttpResponse().statusCode() + "\n\nTopic " + request.topicArn()
                + " updated " + request.attributeName() + " to " + request.attributeValue());

        } catch (SnsException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }

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

// Set the parameters
const params = {
  AttributeName: "ATTRIBUTE_NAME", // ATTRIBUTE_NAME
  TopicArn: "TOPIC_ARN", // TOPIC_ARN
  AttributeValue: "NEW_ATTRIBUTE_VALUE", //NEW_ATTRIBUTE_VALUE
};

const run = async () => {
  try {
    const data = await snsClient.send(new SetTopicAttributesCommand(params));
    console.log("Success.",  data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err.stack);
  }
};
run();
