Obtaining Customized Metadata

After an object is successfully downloaded, its customized data is returned. 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'
});

// Download the object to obtain the object's customized metadata. 
obsClient.getObject({
       Bucket : 'bucketname',
       Key : 'objectkey',
}, (err, result) => {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                  console.log('Metadata-->' + JSON.stringify(result.InterfaceResult.Metadata['property']));
              }
       }
});
