Performing a Streaming 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:

// 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.getObject({ 
       Bucket : 'bucketname', 
       Key : 'objectname', 
       SaveAsStream : true 
}, (err, result) => { 
       if(err){ 
              console.error('Error-->' + err); 
       }else{ 
              console.log('Status-->' + result.CommonMsg.Status); 
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                     // Read the object content.
                     console.log('Object Content:\n'); 
                     result.InterfaceResult.Content.on('data', (data) => { 
                            console.log(data.toString()); 
                     }); 
              }
       } 
});
  • Use the SaveAsStream parameter to specify the download mode to streaming download.
  • InterfaceResult.Content is an instance of stream.Readable and can be used to save the object content to a local file or the memory.
