socket模块判断ip加端口的连通性

def check_connect(host, port):
    sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sk.settimeout(2)
    status = 0
    try:
        sk.connect((host, port))
        print("Server port  OK!")
        sk.close()
        status = 1
    except Exception as e:
        error = str(e)
        print("Server port not OK!")
        sk.close()
    return status
