8 years ago Without previous knowledge of Python and without a working installation this is what I came up with.
def download(argv=None):
if argv is None:
argv = sys.argv[1:]
parser = argparse.ArgumentParser(description='Download a file from Jottacloud.')
parser.add_argument('remotefile', help='The path to the file that you want to download')
parser.add_argument('-l', '--loglevel', help='Logging level. Default: %(default)s.',
choices=('debug', 'info', 'warning', 'error'), default='warning')
parser.add_argument('-c', '--checksum', help='Verfy checksum of file after download')
args = parse_args_and_apply_logging_level(parser, argv)
jfs = JFS.JFS()
root_folder = get_root_dir(jfs)
path_to_object = posixpath.join(root_folder.path, args.remotefile)
remote_file = jfs.getObject(path_to_object)
total_size = remote_file.size
with open(remote_file.name, 'wb') as fh:
bytes_read = 0
with ProgressBar(expected_size=total_size) as bar:
for chunk_num, chunk in enumerate(remote_file.stream()):
fh.write(chunk)
bytes_read += len(chunk)
bar.show(bytes_read)
if args.checksum:
md5 = JFS.calculate_md5(data)
if md5 != JFSFile.md5:
print ('''MD5 hashes don't match!''')
answer = input('Continue: [y/n]')
if not answer or answer[0].lower() != 'y':
print('%s was not downloaded successfully' % args.remotefile')
exit(1)
print('%s downloaded successfully' % args.remotefile)

Via private email, the suggestion was raised that our tools could automatically verify the content after download, by comparing the md5 checksum from jottacloud and that of the newly downloaded file.
Sounds like a nice command line option for
download()incli.py.This would be a nice way to get the know the codebase for beginners.
