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 store = 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 store = new OSS({
region: 'oss-cn-hangzhou',
accessKeyId: '<access-key-id>',
accessKeySecret: '<access-key-secret>',
bucket: '<bucket-name>',
stsToken: '<security-token>'
});
store
.list()
.then(result => {
console.log('objects: %j', result.objects);
return store.put('my-obj', new OSS.Buffer('hello world'));
})
.then(result => {
console.log('put result: %j', result);
return store.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
.
oss(options)
Create a Bucket store instance.
options:
- accessKeyId {String} access key you create on aliyun console website
- accessKeySecret {String} access secret you create
- [stsToken] {String} used by temporary authorization, detail see
- [refreshSTSToken] {Function} used by auto set
stsToken
、accessKeyId
、accessKeySecret
when sts info expires. return value must be object containsstsToken
、accessKeyId
、accessKeySecret
- [refreshSTSTokenInterval] {number} use time (ms) of refresh STSToken interval it should be less than sts info expire interval, default is 300000ms(5min)
- [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
. Set as extranet domain name, intranet domain name, accelerated domain name, etc. according to different needs. please see endpoints - [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 settrue
to save a lot of money. - [secure] {Boolean} instruct OSS client to use HTTPS (secure: true) or HTTP (secure: false) protocol.
- [timeout] {String|Number} instance level timeout for all operations, default is
60s
. - [cname] {Boolean}, default false, access oss with custom domain name. if true, you can fill
endpoint
field with your custom domain name, - [isRequestPay] {Boolean}, default false, whether request payer function of the bucket is open, if true, will send headers
'x-oss-request-payer': 'requester'
to oss server. the details you can see requestPay - [useFetch] {Boolean}, default false, it just work in Browser, if true,it means upload object with
fetch
mode ,elseXMLHttpRequest
- [enableProxy] {Boolean}, Enable proxy request, default is false.
- [proxy] {String | Object}, proxy agent uri or options, default is null.
- [retryMax] {Number}, used by auto retry send request count when request error is net error or timeout. NOTE: Not support
put
with stream,putStream
,append
with stream because the stream can only be consumed once - [maxSockets] {Number} Maximum number of sockets to allow per host. Default is infinity
- [authorizationV4] {Boolean} Use V4 signature. Default is false.
example:
- basic usage
const OSS = require('ali-oss');
const store = new OSS({
accessKeyId: 'your access key',
accessKeySecret: 'your access secret',
bucket: 'your bucket name',
region: 'oss-cn-hangzhou'
});
- use accelerate endpoint
- Global accelerate endpoint: oss-accelerate.aliyuncs.com
- Accelerate endpoint of regions outside mainland China: oss-accelerate-overseas.aliyuncs.com
const OSS = require('ali-oss');
const store = new OSS({
accessKeyId: 'your access key',
accessKeySecret: 'your access secret',
bucket: 'your bucket name',
endpoint: 'oss-accelerate.aliyuncs.com'
});
- use custom domain
const OSS = require('ali-oss');
const store = new OSS({
accessKeyId: 'your access key',
accessKeySecret: 'your access secret',
cname: true,
endpoint: 'your custome domain'
});
- use STS and refreshSTSToken
const OSS = require('ali-oss');
const store = new OSS({
accessKeyId: 'your STS key',
accessKeySecret: 'your STS secret',
stsToken: 'your STS token',
refreshSTSToken: async () => {
const info = await fetch('you sts server');
return {
accessKeyId: info.accessKeyId,
accessKeySecret: info.accessKeySecret,
stsToken: info.stsToken
};
},
refreshSTSTokenInterval: 300000
});
- retry request with stream
for (let i = 0; i <= store.options.retryMax; i++) {
try {
const result = await store.putStream('<example-object>', fs.createReadStream('<example-path>'));
console.log(result);
break; // break if success
} catch (e) {
console.log(e);
}
}
- use V4 signature, and use optional additionalHeaders option which type is a string array, and the values inside need to be included in the header.
const OSS = require('ali-oss');
const store = new OSS({
accessKeyId: 'your access key',
accessKeySecret: 'your access secret',
bucket: 'your bucket name',
region: 'oss-cn-hangzhou',
authorizationV4: true
});
try {
const bucketInfo = await store.getBucketInfo('your bucket name');
console.log(bucketInfo);
} catch (e) {
console.log(e);
}
try {
const putObjectResult = await store.put('your bucket name', 'your object name', {
headers: {
// The headers of this request
'header1': 'value1',
'header2': 'value2'
},
// The keys of the request headers that need to be calculated into the V4 signature. Please ensure that these additional headers are included in the request headers.
additionalHeaders: ['additional header1', 'additional header2']
});
console.log(putObjectResult);
} catch (e) {
console.log(e);
}
