。 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 {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();
