使用 Amazon 开发工具包创建 CloudWatch Logs 订阅筛选条件

以下代码示例说明了如何创建 Amazon CloudWatch Logs 订阅筛选条件。

Java
SDK for Java 2.x

public static void putSubFilters(CloudWatchLogsClient cwl, String filter, String pattern, String logGroup, String functionArn) { try { PutSubscriptionFilterRequest request = PutSubscriptionFilterRequest.builder() .filterName(filter) .filterPattern(pattern) .logGroupName(logGroup) .destinationArn(functionArn) .build(); cwl.putSubscriptionFilter(request); System.out.printf( "Successfully created CloudWatch logs subscription filter %s", filter); } catch (CloudWatchLogsException e) { System.err.println(e.awsErrorDetails().errorMessage()); System.exit(1); } }
  • GitHub 中查找说明和更多代码。

  • 有关 API 的详细信息,请参阅 Amazon SDK for Java 2.x API 参考中的 PutSubscriptionFilter

JavaScript
SDK for JavaScript V3

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. // run();
SDK for JavaScript V2

// Load the AWS SDK for Node.js var AWS = require('aws-sdk'); // Set the region AWS.config.update({region: 'REGION'}); // Create the CloudWatchLogs service object var cwl = new AWS.CloudWatchLogs({apiVersion: '2014-03-28'}); var params = { destinationArn: 'LAMBDA_FUNCTION_ARN', filterName: 'FILTER_NAME', filterPattern: 'ERROR', logGroupName: 'LOG_GROUP', }; cwl.putSubscriptionFilter(params, function(err, data) { if (err) { console.log("Error", err); } else { console.log("Success", data); } });
