Identifying Whether a Bucket Exists

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.headBucket to identify whether a bucket exists. 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({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret Key ***',       
    server : 'https://your-endpoint'
});

obsClient.headBucket({
       Bucket : 'bucketname'
}, (err, result) => {
       if(err){
              console.error('Error-->' + err);
       }else{
              if(result.CommonMsg.Status < 300){
                     console.log('Bucket exists');
              }else if(result.CommonMsg.Status === 404){
                     console.log('Bucket does not exist');
              }
       }
});

If the returned HTTP status code is 404, the bucket does not exist.
