Deleting Versioning Objects

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.

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.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use source codes 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'
});

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

Deleting Versioning Objects in a Batch

You can call ObsClient.deleteObjects to pass the version ID (VersionId) of each to-be-deleted object to delete them. Sample code is as follows:

// Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use source codes 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'
});
 
obsClient.deleteObjects({ 
       Bucket: 'bucketname', 
       // Set the response mode to verbose.
       Quiet : false, 
       Objects : [{Key:'objectname1', VersionId : 'version1'},{Key:'objectname2', VersionId : 'version2'}, {Key : 'objectname3', 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']); 
                     }
              }
       } 
});
