Obtaining the Upload Progress (SDK for Java)

Function

You can call PutObjectRequest.setProgressListener to set a data transmission listener to obtain the upload progress of a specified object.

If you have any questions during development, post them on the Issues page of GitHub.

Restrictions

  • To obtain the upload progress, you must have the obs:object:PutObject permission. For details about permission granting, see Typical Permission Control Scenarios.
  • The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
  • You can query the upload progress when uploading an object in streaming, file-based, multipart, appendable, or resumable mode.
  • If -1 is returned for ProgressStatus.getTransferPercentage(), the object is uploaded in streaming mode and the object length (Content-Length) is not set. To obtain the upload progress, you must set Content-Length.
