Like try to download a 500 MB .mp4 file using requests, you want to stream the response (and write the stream in chunks of chunk_size) instead of waiting for all 500mb to be loaded into python at once. If you want to implement any UI feedback (such as download progress like...
with requests.get(url, stream=True) as r: r.raise_for_status() with open(local_filename, 'wb') as f: for chunk in r.iter_content(chunk_size=8192): f.write(chunk) return local_filename 1. 2. 3. 4. 5. 6. 7. 8. 9. 如果你有对 chunk 编码的需求,那就不该传入 chunk_size ...
len(chunk)表示实际读取到每块的视频文件大小。 for chunk in res.iter_content(128): download_size += len(chunk) file_object.write(chunk) file_object.flush() message = "视频总大小为:{}字节,已下载{}字节。".format(file_size, download_size) print(message) file_object.close() res.close() ...

getsizeof(object[, default]) 以字节为单位返回对象的大小。 setswitchinterval(interval) 设置线程切换的时间间隔。 getswitchinterval() 返回线程切换时间间隔。 pip命令 2021年11月30日 13:23 pip使用 安装包 pip install package_name 查看某个已安装包 ...
Use requests.Session(), not requests. 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.rais...
This module contains all of the network related requests. This module will check for all the exceptions while making the network calls and raise exceptions for any unknown exception. Make sure that when you use this module, you handle these exceptions in client code as: ...
Pyenv 往往是为本地开发安装 Python 的最高投资回报。初始设置确实有一些微妙之处。然而,它允许根据需要并排安装任意多的 Python 版本。它允许管理一个将被访问的方式:基于每个用户的默认或每个目录的默认。 安装pyenv 本身依赖于操作系统。在 Mac OS X 上,最简单的方法是通过自制软件安装。注意,在这种情况下,pyenv...
