Obtaining a Versioning Object

You can call ObsClient.getObject and specify the VersionId parameter to obtain a versioning object. Sample code is as follows:

// Import the OBS library.
var ObsClient = require('./lib/obs');

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret Key ***',       
    server : 'yourdomainname'
});

// Specify versionId to obtain versioning objects.
obsClient.getObject({
       Bucket : 'bucketname',
       Key : 'objectkey',
       VersionId : 'versionid'
}, (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.toString());
              }
       }
});
NOTE:

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