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和客户端模块并调用API。

import { GetTopicAttributesCommand } from "@aws-sdk/client-sns"; import { snsClient } from "../libs/snsClient.js"; /** * @param {string} topicArn - The ARN of the topic to retrieve attributes for. */ export const getTopicAttributes = async (topicArn = "TOPIC_ARN") => { const response = await snsClient.send( new GetTopicAttributesCommand({ TopicArn: topicArn, }), ); console.log(response); // { // '$metadata': { // httpStatusCode: 200, // requestId: '36b6a24e-5473-5d4e-ac32-ff72d9a73d94', // extendedRequestId: undefined, // cfId: undefined, // attempts: 1, // totalRetryDelay: 0 // }, // Attributes: { // Policy: '{...}', // Owner: 'xxxxxxxxxxxx', // SubscriptionsPending: '1', // TopicArn: 'arn:aws:sns:us-east-1:xxxxxxxxxxxx:mytopic', // TracingConfig: 'PassThrough', // EffectiveDeliveryPolicy: '{"http":{"defaultHealthyRetryPolicy":{"minDelayTarget":20,"maxDelayTarget":20,"numRetries":3,"numMaxDelayRetries":0,"numNoDelayRetries":0,"numMinDelayRetries":0,"backoffFunction":"linear"},"disableSubscriptionOverrides":false,"defaultRequestPolicy":{"headerContentType":"text/plain; charset=UTF-8"}}}', // SubscriptionsConfirmed: '0', // DisplayName: '', // SubscriptionsDeleted: '1' // } // } return response; };
