Незначительные изменения в ответе Триптиха, позволяющие фактически записать файл (python3):
from urllib.request import urlopen
def chunk_report(bytes_so_far, chunk_size, total_size):
percent = float(bytes_so_far) / total_size
percent = round(percent*100, 2)
sys.stdout.write("Downloaded %d of %d bytes (%0.2f%%)\r" %
(bytes_so_far, total_size, percent))
if bytes_so_far >= total_size:
sys.stdout.write('\n')
def chunk_read(response, chunk_size=8192, report_hook=None):
total_size = response.info().get("Content-Length").strip()
total_size = int(total_size)
bytes_so_far = 0
data = b""
while 1:
chunk = response.read(chunk_size)
bytes_so_far += len(chunk)
if not chunk:
break
if report_hook:
report_hook(bytes_so_far, chunk_size, total_size)
data += chunk
return data
Использование:
with open(out_path, "wb") as f:
response = urlopen(filepath)
data_read = chunk_read(response, report_hook=chunk_report)
f.write(data_read)
