使用 Amazon 软件开发工具包描述 CloudWatch Logs 订阅筛选条件

以下代码示例说明了如何描述 Amazon CloudWatch Logs 现有的订阅筛选条件。

Java
SDK for Java 2.x

public static void describeFilters(CloudWatchLogsClient logs, String logGroup) { try { boolean done = false; String newToken = null; while(!done) { DescribeSubscriptionFiltersResponse response; if (newToken == null) { DescribeSubscriptionFiltersRequest request = DescribeSubscriptionFiltersRequest.builder() .logGroupName(logGroup) .limit(1).build(); response = logs.describeSubscriptionFilters(request); } else { DescribeSubscriptionFiltersRequest request = DescribeSubscriptionFiltersRequest.builder() .nextToken(newToken) .logGroupName(logGroup) .limit(1).build(); response = logs.describeSubscriptionFilters(request); } for(SubscriptionFilter filter : response.subscriptionFilters()) { System.out.printf( "Retrieved filter with name %s, " + "pattern %s " + "and destination arn %s", filter.filterName(), filter.filterPattern(), filter.destinationArn()); System.out.println(""); } if(response.nextToken() == null) { done = true; } else { newToken = response.nextToken(); } } } catch (CloudWatchException e) { System.err.println(e.awsErrorDetails().errorMessage()); System.exit(1); } System.out.printf("Done"); }
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 { DescribeSubscriptionFiltersCommand } from "@aws-sdk/client-cloudwatch-logs"; import { cwlClient } from "./libs/cloudWatchLogsClient.js"; // Set the parameters export const params = { logGroupName: "GROUP_NAME", //GROUP_NAME limit: 5 }; export const run = async () => { try { const data = await cwlClient.send( new DescribeSubscriptionFiltersCommand(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 = { logGroupName: 'GROUP_NAME', limit: 5 }; cwl.describeSubscriptionFilters(params, function(err, data) { if (err) { console.log("Error", err); } else { console.log("Success", data.subscriptionFilters); } });

suspend fun describeFilters(logGroup: String) { val request = DescribeSubscriptionFiltersRequest { logGroupName = logGroup limit = 1 } CloudWatchLogsClient { region = "us-west-2" }.use { cwlClient -> val response = cwlClient.describeSubscriptionFilters(request) response.subscriptionFilters?.forEach { filter -> println("Retrieved filter with name ${filter.filterName} pattern ${filter.filterPattern} and destination ${filter.destinationArn}" ) } } }
