oss-js-sdk

aliyun OSS(Object Storage Service) js client for Node and Browser env.

NOTE： For SDK 5.X document, please go to README.md

Install

npm install ali-oss --save

Compatibility

Node

Node.js >= 8.0.0 required. You can use 4.x in Node.js < 8.

Browser

IE >= 10 & Edge
Major versions of Chrome/Firefox/Safari
Major versions of Android/iOS/WP

Note: For Lower browsers you can refer to PostObject, if you want to see more practices ,please refer to Web Post

OSS Usage

OSS, Object Storage Service. Equal to well known Amazon S3.

All operation use es7 async/await to implement. All api is async function.

Summary

Node Usage

Compatibility

Node: >= 8.0.0

Basic usage

1.install SDK using npm

npm install ali-oss --save

2.for example:

const OSS = require('ali-oss');
const client = new OSS({
  region: '<oss region>',
  accessKeyId: '<Your accessKeyId>',
  accessKeySecret: '<Your accessKeySecret>',
  bucket: '<Your bucket name>'
});

Browser Usage

You can use most of the functionalities of ali-oss in browser with some exceptions:

put object with streaming: no chunked encoding, we use multipart upload instead
get object to local file: we cannot manipulate file system in browser, we provide signed object url for downloading needs
bucket operations(listBuckets, putBucketLogging, etc) will fail: OSS server currently do not support CORS requests for bucket operations (will probably be fixed later)

Compatibility

IE >= 10 & Edge
Major versions of Chrome/Firefox/Safari
Major versions of Android/iOS/WP
Note: Because some browsers do not support promises, you need to introduce promise compatible libraries. For example: IE10 and IE11 need to introduce a promise-polyfill.

Setup

Bucket setup

As browser-side javascript involves CORS operations. You need to setup your bucket CORS rules to allow CORS operations:

set allowed origins to '*'
allowed methods to 'PUT, GET, POST, DELETE, HEAD'
set allowed headers to '*'
expose 'ETag' in expose headers

STS setup

As we don't want to expose the accessKeyId/accessKeySecret in the browser, a [common practice][oss-sts] is to use STS to grant temporary access.

Basic usage

Include the sdk lib in the <script> tag and you have OSS available for creating client.

 // x.x.x The specific version number represented 
 // we recommend introducing offline resources, because the usability of online resources depends on the stability of the cdn server. 
 <!-- Introducing online resources -->
 <script src="http://gosspublic.alicdn.com/aliyun-oss-sdk-x.x.x.min.js"></script>
 <!-- Introducing offline resources -->
 <script src="./aliyun-oss-sdk-x.x.x.min.js"></script>

<script type="text/javascript">
  const client = new OSS({
    region: 'oss-cn-hangzhou',
    accessKeyId: '<access-key-id>',
    accessKeySecret: '<access-key-secret>',
    bucket: '<bucket-name>'
  });

  client.list().then((result) => {
    console.log('objects: %j', result.objects);
    return client.put('my-obj', new OSS.Buffer('hello world'));
  }).then((result) => {
    console.log('put result: %j', result);
    return client.get('my-obj');
  }).then((result) => {
    console.log('get result: %j', result.content.toString());
  });
</script>

Create Account

Go to OSS website, create a new account for new user.

After account created, you can create the OSS instance and get the accessKeyId and accessKeySecret.

Create A Bucket Instance

Each OSS instance required accessKeyId, accessKeySecret and bucket.
