f = open(file_name, ‘wb’)
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
data_to_read = True
while data_to_read:
data = bytearray()
red = 0
while red < chunk_size:
chunk = await response.content.read(chunk_size - red)
if not chunk:
data_to_read = False
break
data.extend(chunk)
red += len(chunk)
f.write(data)
f.close()
