我如何在Node中使用亚马逊的Dynamodb Local？

Question

亚马逊提供local simulator for their Dynamodb product但examples are only in PHP。

这些示例提到传递参数“base_url”以指定您正在使用本地Dynamodb，但是在Node中返回此错误：

{ [UnrecognizedClientException: The security token included in the request is invalid.]
  message: 'The security token included in the request is invalid.',
  code: 'UnrecognizedClientException',
  name: 'UnrecognizedClientException',
  statusCode: 400,
  retryable: false }

如何让Dynamodb_local在Node中工作？

Answer 1

你应该按照这个blog post设置你的DynamoDB Local，然后你可以简单地使用这个代码：

var AWS= require('aws-sdk'),
dyn= new AWS.DynamoDB({ endpoint: new AWS.Endpoint('http://localhost:8000') });

dyn.listTables(function (err, data)
{
   console.log('listTables',err,data);
});

Answer 2

对于Node，请执行以下操作：

const AWS = require('aws-sdk');
const AWSaccessKeyId = 'not-important';
const AWSsecretAccessKey = 'not-important';      
const AWSregion = 'local';
const AWSendpoint = 'http://localhost:8000' // This is required
AWS.config.update({
    accessKeyId: AWSaccessKeyId,
    secretAccessKey: AWSsecretAccessKey,  
    region: AWSregion,
    endpoint: AWSendpoint
});

确保DynamodDB在端口8000上运行。
