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!');
});
Will choose an alive client by schedule(masterSlave or roundRobin).
client.get()client.head()client.getStream()client.list()client.signatureUrl()client.chooseAvailable() - choose an available client by schedule.Will put to all clients.
client.put()client.putStream()client.delete()client.deleteMulti()client.copy()client.putMeta()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;
var STS = OSS.STS;
var client = new OSS({ /* same options */});
client.put('hello', new Buffer('world')).then(function (val) {
console.log('result: %j', val);
}).catch (function (err) {
console.log('error: %j', err);
});
client.get('hello').then(function (val) {
console.log('result: %j', val);
}).catch (function (err) {
console.log('error: %j', err);
});
var url = client.signatureUrl('hello');
console.log(url);
var stsClient = new STS({ /* same options */});
var role = 'role';
stsClient.assumeRole(role).then(function (val) {
console.log('result: %j', val);
}).catch (function (err) {
console.log('error: %j', err);
});
You can use most of the functionalities of ali-oss in browser with
some exceptions:
As browser-side javascript involves CORS operations. You need to setup your bucket CORS rules to allow CORS operations:
As we don't want to expose the accessKeyId/accessKeySecret in the browser, a common practice is to use STS to grant temporary access.
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>
