python : Check if IRC connection is lost (PING PONG )

所以我的问题是，如果有 PING，我如何让我的机器人收听，如果在一分钟的时间间隔内没有 ping，它会使用react，就好像连接已经丢失一样。怎么做到这一点？

编辑:

这是注册连接失败的工作代码(尽管在重新连接时遇到问题):

#!/usr/bin/env python 
# -*- coding: utf-8 -*- 
 
import sys 
import socket 
import string 
import os 
import platform 
import time 
 
# Variables 
HOST = "irc.channel.net" 
PORT = 6667 
NICK = "Botname" 
IDENT = "Botname" 
REALNAME = os.getenv('USER') 
CHAN = "##ChannelName" 
readbuffer = "" 
 
# Our IRC connection 
irc = socket.socket() 
irc.settimeout(300) 
connected = False 
def connection(host, port, nick, ident, realname, chan): 
    while connected is False: 
        try: 
            irc.connect((host, port)) 
            irc.send("NICK %s\r\n" % nick) 
            irc.send("USER %s %s bla :%s\r\n" % (ident, host, realname)) 
            irc.send("JOIN :%s\r\n" % chan) 
            # Initial msg to send when bot connects 
            irc.send("PRIVMSG %s :%s\r\n" % (chan, "TehBot: "+ nick + " Realname: " + realname + " .")) 
            global connected 
            connected = True 
        except socket.error: 
            print "Attempting to connect..." 
            time.sleep(5) 
            continue 
connection(HOST, PORT, NICK, IDENT, REALNAME, CHAN) 
 
while connected: 
    try: 
        data = irc.recv ( 4096 ) 
        # If connection is lost 
        if len(data) == 0: 
            break 
        print data 
        # If Nick is in use 
        if data.find ( "Nickname is already in use" ) != -1: 
            NICK = NICK + str(time.time()) 
            connection(HOST, PORT, NICK, IDENT, REALNAME, CHAN) 
        # Ping Pong so we don't get disconnected 
        if data[0:4] == "PING": 
            irc.send ( "PONG " + data.split() [ 1 ] + "\r\n" ) 
    except socket.timeout: 
        global connected 
        connected = False 
        print connected 
        break 
print "Out of loop" 
connection(HOST, PORT, NICK, IDENT, REALNAME, CHAN) 

请您参考如下方法:

last_ping = time.time() 
threshold = 5 * 60 # five minutes, make this whatever you want 
while connected: 
    data = irc.recv ( 4096 ) 
    # If Nick is in use 
    if data.find ( 'Nickname is already in use' ) != -1: 
        NICK = NICK + str(time.time()) 
        Connection() 
    # Ping Pong so we don't get disconnected 
    if data.find ( 'PING' ) != -1: 
        irc.send ( 'PONG ' + data.split() [ 1 ] + '\r\n' ) 
        last_ping = time.time() 
    if (time.time() - last_ping) > threshold: 
        break 

这将在每次收到 ping 时记录时间，如果没有 ping 的时间太长，则跳出 connected 循环。您不需要 while connected == True:，只需 while connected: 做同样的事情。

此外，请考虑使用 connection 而不是 Connection，这是 Python 约定，仅对类使用大写名称。
