问题描述
在翻译bash中的某些脚本时，我遇到了netstat -an的许多用法，以发现我们的服务之一是否正在监听.虽然我知道我可以只使用subprocess.call或其他甚至popen的方法，但我宁愿使用pythonic解决方案，因此我不会利用我们正在操作的unix环境.
In translating some scripts from bash, I am encountering many uses of netstat -an to find if one of our services is listening. While I know I can just use subprocess.call or other even popen I would rather use a pythonic solution so I am not leveraging the unix environment we are operating in.
从我读过的内容来看，套接字模块应该有一些东西，但是我没有看到任何检查监听端口的东西.可能是我不了解一个简单的技巧，但是到目前为止，我知道如何连接到套接字，并且编写了一些可以让我知道该连接何时失败的内容.但是不一定我找到了专门检查端口以查看其是否在监听的东西.
From what I have read the socket module should have something but I haven't seen anything that checks for listening ports. It could be me not understanding a simple trick, but so far I know how to connect to a socket, and write something that lets me know when that connection failed. But not necessarily have I found something that specifically checks the port to see if its listening.
有什么想法吗?
推荐答案
如何尝试连接...
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = s.connect_ex(('127.0.0.1', 3306))
if result == 0:
print('socket is open')
s.close()
