使用Python请求时如何获取基础套接字 [英] How to get the underlying socket when using Python requests
问题描述
我有一个Python脚本,它使用请求库创建了许多短暂的同时连接.我特别需要找出每个连接使用的源端口,并且我认为我需要为此访问底层套接字.有没有办法通过响应对象来做到这一点?
I have a Python script that creates many short-lived, simultaneous connections using the requests library. I specifically need to find out the source port used by each connection and I figure I need access to the underlying socket for that. Is there a way to get this through the response object?
推荐答案
对于流连接(使用stream=True
参数打开的连接),可以在响应对象上调用.raw.fileno()
方法以获取打开的文件描述符.
For streaming connections (those opened with the stream=True
parameter), you can call the .raw.fileno()
method on the response object to get an open file descriptor.
您可以使用socket.fromfd(...)
方法从描述符创建Python套接字对象:
You can use the socket.fromfd(...)
method to create a Python socket object from the descriptor:
>>> import requests
>>> import socket
>>> r = requests.get('http://google.com/', stream=True)
>>> s = socket.fromfd(r.raw.fileno(), socket.AF_INET, socket.SOCK_STREAM)
>>> s.getpeername()
('74.125.226.49', 80)
>>> s.getsockname()
('192.168.1.60', 41323)
对于非流套接字,在返回响应对象之前清理文件描述符.据我所知,在这种情况下是无法实现的.
For non-streaming sockets, the file descriptor is cleaned up before the response object is returned. As far as I can tell there's no way to get it in this situation.
