Obtaining Download Progresses

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 GetObjectRequest.setProgressInterval to configure the data transmission interface to obtain download progresses. Sample code is as follows:

String endPoint = "https://your-endpoint";
String ak = "*** Provide your Access Key ***";
String sk = "*** Provide your Secret Key ***";

// Create an instance of ObsClient.
final ObsClient obsClient = new ObsClient(ak, sk, endPoint);

GetObjectRequest request = new GetObjectRequest("bucketname", "objectname");
request.setProgressListener(new ProgressListener() {
       
       @Override
       public void progressChanged(ProgressStatus status) {
              // Obtain the average download rate.
              System.out.println("AverageSpeed:" + status.getAverageSpeed());
              // Obtain the download progress in percentage.
              System.out.println("TransferPercentage:" + status.getTransferPercentage());
       }
});
// Refresh the upload progress each time 1 MB data is downloaded.
request.setProgressInterval(1024 * 1024L);
ObsObject obsObject = obsClient.getObject(request);

// Read the object contents.
System.out.println("Object content:");
InputStream input = obsObject.getObjectContent();
byte[] b = new byte[1024];
ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
int len;
while ((len=input.read(b)) != -1){
       bos.write(b, 0, len);
}
 
System.out.println(new String(bos.toByteArray()));
bos.close();
input.close();

You can obtain the download progress when downloading an object in streaming, partial, or resumable mode.
