亚马逊推出 AWS SDK for Node.js

AWS（Amazon Web Services，亚马逊网络服务）开发团队今天发布了AWS SDK for Node.js，基于JavaScript实现。 

通过AWS SDK for Node.js，开发者可以在几分钟内在应用程序中集成AWS服务，包括Amazon DynamoDB、Amazon Simple Storage Service （S3）、Amazon Elastic Compute Cloud（EC2）和Amazon Simple Workflow Service（SWF）等。 

目前该SDK还处于开发者预览版阶段，感兴趣的开发者可通过NPM或GitHub下载、测试、反馈。 

在应用程序代码中加载并配置： 

var AWS = require('aws-sdk');

AWS.config.update({
  accessKeyId: 'ACCESS_KEY',
  secretAccessKey: 'SECRET_KEY',
  region: 'us-east-1'
});

接下来，创建一个服务接口对象： 

var s3 = new AWS.S3();

然后使用对象发起请求。下面代码实现了同时上传一组对象到Amazon S3： 

var params1 = {Bucket: 'myBucket', Key: 'myKey1', Body: 'Hello!'};
var params2 = {Bucket: 'myBucket', Key: 'myKey2', Body: 'World!'};

s3.client.putObject(params1).done(function(resp) {
  console.log("Successfully uploaded data to myBucket/myKey1");
});

s3.client.putObject(params2).done(function(resp) {
  console.log("Successfully uploaded data to myBucket/myKey2");
});
