Configuring Lifecycle Management

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

When uploading an object or initiating a multipart upload, you can directly set the expiration time for the object. Sample code is as follows:

// Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use the source code to install the client.
// var ObsClient = require('./lib/obs');

// Create an instance of ObsClient.
var obsClient = new ObsClient({
       //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways. Using hard coding may result in leakage.
       //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
       access_key_id: process.env.ACCESS_KEY_ID,
       secret_access_key: process.env.SECRET_ACCESS_KEY,
       server : 'https://your-endpoint'
});

// When uploading an object, set the object to expire after 30 days.
obsClient.putObject({
       Bucket : 'bucketname',
       Key : 'objectname',
       Body : 'Hello OBS',
       Expires : 30
}, (err, result) => {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});

// When initiating a multipart upload, configure the object to expire 60 days after combination.
obsClient.initiateMultipartUpload({
       Bucket : 'bucketname',
       Key : 'objectname',
       ContentType : 'text/plain',
       Expires : 60
}, (err, result) => {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                     console.log('UploadId-->' + result.InterfaceResult.UploadId);
              }
       }
});

• Use the Expires parameter to specify expiration time for the object.
• The previous mode specifies the time duration in days after which an object will expire. The OBS server automatically clears expired objects.
• The object expiration time set in the preceding method takes precedence over the bucket lifecycle rule.
