Obtaining a Versioning Object

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.

You can call ObsClient.getObject to obtain a versioning object by specifying the version ID (VersionId). 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'
});

// Set the version ID to obtain a versioning object.
obsClient.getObject({
       Bucket : 'bucketname',
       Key : 'objectname',
       VersionId : 'versionid'
}, function (err, result) {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                  console.log('Content-->' + result.InterfaceResult.Content);
              }
       }
});

If the version ID is null, the object of the latest version will be downloaded, by default.
