Performing a Binary Download

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.

Sample code:

// 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.getObject({ 
       Bucket : 'bucketname', 
       Key : 'objectname', 
       SaveByType : 'arraybuffer' 
}, function (err, result) { 
       if(err){ 
              console.error('Error-->' + err); 
       }else{ 
              console.log('Status-->' + result.CommonMsg.Status); 
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){ 
                     // Obtain the object length.
                     console.log('Object Length:\n'); 
                     console.log(result.InterfaceResult.Content.byteLength); 
              }
       } 
});
  • Set the SaveByType parameter to arraybuffer to use binary download.
  • In the returned result of a binary download, InterfaceResult.Content is an instance of ArrayBuffer.
