获取端口信息.md

你可以使用Python的subprocess模块来运行shell命令，然后解析输出结果。这里是一个例子：

import subprocess

def get_active_ports():
    # Run the 'netstat' command to get active ports
    command = "sudo netstat -tuln"
    process = subprocess.Popen(command.split(), stdout=subprocess.PIPE)
    output, error = process.communicate()

    # If there was an error, print it and return
    if error:
        print(f"Error: {error}")
        return

    # Split the output into lines
    lines = output.decode().split("\n")

    # The first two lines are headers, so ignore them
    lines = lines[2:]

    # Parse each line
    for line in lines:
        # Ignore empty lines
        if not line:
            continue

        # Split the line into parts
        parts = line.split()

        # The fourth part is the address and port
        address, port = parts[3].rsplit(":", 1)

        # The sixth part is the process ID and name
        process_info = parts[6] if len(parts) > 6 else "N/A"

        # Print the information
        print(f"Address: {address}, Port: {port}, Process: {process_info}")

get_active_ports()

注意，这段代码需要在具有sudo权限的环境中运行，因为netstat -tuln命令需要sudo权限。如果你不希望使用sudo，你可以尝试使用ss -tuln命令，但是这个命令可能无法提供进程信息。

此外，这段代码假设输出的格式是固定的，如果实际的输出格式与这个假设不符，可能需要调整代码。
