在python中，有一种跨平台的方法来确定正在侦听给定端口的进程? [英] In python is there a cross-platform way of determining what process is listening to a given port?

问题描述

在linux中，我可以使用 lsof -i ，如以下功能所示:

In linux, I can use lsof -i as in the following function:

def FindProcessUsingPort(portnum):
    import os
    fp = os.popen("lsof -i :%s" % portnum)
    lines = fp.readlines()
    fp.close()
    pid = None
    if len(lines) >= 2:
        pid = int(lines[1].split()[1])
    return pid

是否有跨平台的方法可以解决这个问题?

Is there a cross-platform way to figure this out?

作为相关参考，一旦我知道了进程ID， psutil 库就非常有用.很好，让我以跨平台的方式为它确定各种有用的过程信息.我现在暂时无法跨平台工作(找到pid).

As a relevant reference, once I know the process id, the psutil library is very nice and lets me determine all sorts of useful process information for it in a cross-platform way. I just can't get the first part to work (finding the pid) cross-platform at the moment.

如果不熟悉 lsof -i 开关，则输出如下所示(在启动python进程后，该进程打开了一个侦听端口1234的TCP套接字):

If not familiar with the lsof -i switch, the output looks like below (after launching a python process that opens a TCP socket listening on port 1234):

$ lsof -i :1234
COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
python  22380 russ   15u  IPv4 4015476      0t0  TCP *:1234 (LISTEN)

推荐答案

不，这不是python内置的.

No, this is not built into python.
