"Download media resources. Note that the Python file object is compatible with io.Base and can be used with this class also. Example: request = farms.animals().get_media(id='cow') fh = io.FileIO('cow.png', mode='wb') downloader = MediaIoBaseDownload(fh, request, chunksize=1024*1024) done = False while done is False: status, done = downloader.next_chunk() if status: print "Download %d%%." % int(status.progress() * 100) print "Download Complete!"

Constructor.

Args:
  fd: io.Base or file object, The stream in which to write the downloaded

    chunks.

next_chunk(*args, **kwargs)

source code

Get the next chunk of the download.

Args:
  num_retries: Integer, number of times to retry with randomized
        exponential backoff. If all retries fail, the raised HttpError
        represents the last request. If zero (default), we attempt the
        request only once.

Returns:
  (status, done): (MediaDownloadProgress, boolean)
     The value of 'done' will be True when the media has been fully
     downloaded or the total size of the media is unknown.

Raises:
  googleapiclient.errors.HttpError if the response was not a 2xx.
  httplib2.HttpLib2Error if a transport error has occurred.
