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 initializing a multipart upload, you can directly set the expiration time for the object. Sample code is as follows:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret 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
}, function(err, result){
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});

// When initializing a multipart upload, set the object to expire 60 days after combination.
obsClient.initiateMultipartUpload({
       Bucket : 'bucketname',
       Key : 'objectname',
       ContentType : 'text/plain',
       Expires : 60
}, function(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.
