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.

#oss(options)

Create a Bucket store instance.

options:

accessKeyId {String} access key you create on aliyun console website
accessKeySecret {String} access secret you create
[bucket] {String} the default bucket you want to access If you don't have any bucket, please use putBucket() create one first.
[endpoint] {String} oss region domain. It takes priority over region.
[region] {String} the bucket data region location, please see Data Regions, default is oss-cn-hangzhou.
[internal] {Boolean} access OSS with aliyun internal network or not, default is false. If your servers are running on aliyun too, you can set true to save lot of money.

Cluster Mode

Cluster mode now only support object operations.

var Cluster = require('ali-oss').ClusterClient;

var client = Cluster({
  cluster: [{
    host: 'host1',
    accessKeyId: 'id1',
    accessKeySecret: 'secret1'
  }, {
    host: 'host2',
    accessKeyId: 'id2',
    accessKeySecret: 'secret2'
  }],
  schedule: 'masterSlave', //default is `roundRobin`
});

// listen error event to logging error
client.on('error', function(err) {
  console.error(err.stack);
});

// client init ready
client.ready(function() {
  console.log('cluster client init ready, go ahead!');
});

Get Methods

Will choose an alive client by schedule(masterSlave or roundRobin).

client.get()

Wrapper Usage

We provide an async wrapper which can be used without co. All the methods are preserved, just in a async way:

var OSS = require('ali-oss').Wrapper;

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

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 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. We use OSS.Wrapper here to avoid using co:

<script src="http://gosspublic.alicdn.com/aliyun-oss-sdk.min.js"></script>
<script type="text/javascript">
  var client = new OSS.Wrapper({
    region: 'oss-cn-hangzhou',
    accessKeyId: '<access-key-id>',
    accessKeySecret: '<access-key-secret>',
    bucket: '<bucket-name>'
  });

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