iter_content(chunk_size=128) 当流下载时,用Response.iter_content或许更方便些。requests.get(url)默认是下载在内存中的,下载完成才存到硬盘上,可以用Response.iter_content来边下载边存硬盘
Why should I use iter_content and specially I'm really confused with the purpose using of chunk_size , as I have tried using it and in every way the file seems to be saved after downloading successfully. g = requests.get(url, stream=True) with open('c:/users/andriken/desktop...
Set chunk_size=None in iter_content. Here, have an example: # requests_bug.py import requests def iterate_through_streamed_content(requests_module_or_session, chunk_size): r = requests_module_or_session.get('http://example.org', stream=True) r.raise_for_status() for chunk in r.iter...
According to the documentation when stream=True iter_content(chunk_size=None) "will read data as it arrives in whatever size the chunks are received", But it actually collects all input into a single big bytes object consuming large amou...
