我的问题
我正在编写一个简单的 js 函数,用于从 AWS CloudWatch Logs 读取一些信息。
按照 Configuring region in Node.js AWS SDK 的回答, 和 AWS nodejs SDK documentation ,我想出了以下内容:
代码
var AWS = require('aws-sdk');
var cloudwatchlogs = new AWS.CloudWatchLogs();
console.log(AWS.config.region) // Undefined
AWS.config.region = 'eu-central-1' // Define the region with dot notation
console.log(AWS.config.region) . // eu-central-1
AWS.config.update({region:'eu-central-1'}); // Another way to update
console.log(AWS.config.region) . // eu-central-1
var params = {
limit: 0,
// logGroupNamePrefix: 'STRING_VALUE',
// nextToken: 'STRING_VALUE'
};
// This call is failing
cloudwatchlogs.describeLogGroups(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
输出和错误
undefined
eu-central-1
eu-central-1

最佳答案
或者,您可以在创建 cloudwatch 对象时指定:
var AWS = require('aws-sdk');
var cloudwatchlogs = new AWS.CloudWatchLogs({region: 'eu-central-1'});
