Deleting Versioning Objects

Deleting a Single Versioning Object

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

obsClient.deleteObject({
       Bucket : 'bucketname',
       Key : 'objectkey',
       VersionId : 'versionid'
}, (err, result) => {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});

Batch Deleting Versioning Objects

You can call ObsClient.deleteObjects to pass the version ID (VersionId) of each to-be-deleted object to batch delete them. 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' 
}); 
 
obsClient.deleteObjects({ 
       Bucket: 'bucketname', 
       Key : 'objectkey', 
// Set the response mode to verbose.
       Quiet : false, 
       Objects : [{Key:'objectkey1', VersionId : 'version1'},{Key:'objectkey2', VersionId : 'version2'}, {Key : 'objectkey3', VersionId : 'version3'}] 
}, (err, result) => { 
       if(err){ 
              console.log('Error-->' + err); 
       }else{ 
              console.log('Status-->' + result.CommonMsg.Status); 
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
// Obtain information about successfully deleted objects.
                     console.log('Deleteds:'); 
                     for(let i=0;i<result.InterfaceResult.Deleteds.length;i++){ 
                            console.log('Deleted[' + i + ']:'); 
                            console.log('Key-->'+result.InterfaceResult.Deleteds[i]['Key']); 
                            console.log('VersionId-->' + result.InterfaceResult.Deleteds[i]['VersionId']); 
                     } 
// Obtain information about objects failed to be deleted.
                     console.log('Errors:'); 
                     for(let j=0;j<result.InterfaceResult.Errors.length;j++){ 
                            console.log('Error[' + j + ']:'); 
                            console.log('Key-->' + result.InterfaceResult.Errors[j]['Key']); 
                            console.log('VersionId-->' + result.InterfaceResult.Errors[j]['VersionId']); 
                     }
              }
       } 
});
