如何在AWS js SDK中配置区域？ [英] How to configure the region in the AWS js SDK?

问题描述

我正在编写一个简单的js函数，该函数从AWS CloudWatch Logs中读取一些信息。

I am writing a simple js function that reads some information from AWS CloudWatch Logs.

按照在Node.js AWS开发工具包中配置区域的答案，以及 AWS nodejs SDK文档，提出以下内容：

Following the answer at Configuring region in Node.js AWS SDK, and the AWS nodejs SDK documentation, I came up with the following:

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

如何在AWS js SDK中正确配置区域？

打开 github上的一个问题并得到一些

推荐答案

或者，也可以在创建c时指定扬声器对象：

Or, alternatively, you can specify that when creating your cloudwatch object:

var AWS = require('aws-sdk');
var cloudwatchlogs = new AWS.CloudWatchLogs({region: 'eu-central-1'});
