Obtaining Object Properties

You can call ObsClient.getObjectMetadata to obtain properties of an object, including the length, MIME type, customized metadata. 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.getObjectMetadata({
       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(result.InterfaceResult.ContentType);
              console.log(result.InterfaceResult.ContentLength);    
              console.log(result.InterfaceResult.Metadata['property']); 
          }
       }
});
