要了解如何设置和运行此示例，请参阅GitHub.

在单独的模块中创建客户端并将其导出。

import { CloudWatchLogsClient } from "@aws-sdk/client-cloudwatch-logs";
// Set the AWS Region.
const REGION = "REGION"; //e.g. "us-east-1"
// Create an Amazon CloudWatch Logs service client object.
export const cwlClient = new CloudWatchLogsClient({ region: REGION });

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 {
  PutSubscriptionFilterCommand,
} from "@aws-sdk/client-cloudwatch-logs";
import { cwlClient } from "./libs/cloudWatchLogsClient.js";

// Set the parameters
export const params = {
  destinationArn: "LAMBDA_FUNCTION_ARN", //LAMBDA_FUNCTION_ARN
  filterName: "FILTER_NAME", //FILTER_NAME
  filterPattern: "ERROR",
  logGroupName: "LOG_GROUP", //LOG_GROUP
};

export const run = async () => {
  try {
    const data = await cwlClient.send(new PutSubscriptionFilterCommand(params));
    console.log("Success", data.subscriptionFilters);
    return data; //For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};
// Uncomment this line to run execution within this file.
