我正在使用一个脚本，当指定的Twitch电视频道播出时播放到IRC。
但由于某些原因，我上网时一直收到错误。但是当它离线时它完全正常。
Python代码：
# Twitch IRC status autoupdate
# Create an empty file called config.yml in the same directory, containing:
# host: irc.quakenet.org
# port: 6667
# channels: ["#channel", "#anotherchannel"]
# nspass: "nickserv/Q password"
# password: "server password for BNC or private server"
# twitch: "channelname"

#Nickserv
self._send_message("identify %s %s" % (self.nickname, config["nspass"]), "NickServ")
#Nickserv that doesn't support specifying a nickname
self._send_message("identify %s" % config["nspass"], "NickServ")
def restartloop(reason):

print "Loop crashed: " + reason.getErrorMessage()
self.loopcall.start(5.0).addErrback(restartloop)
self.loopcall = task.LoopingCall(self.getTwitchStatus)
self.loopcall.start(5.0).addErrback(restartloop)
def getTwitchStatus(self):

def privmsg(self, user, channel, message):
nick, _, host = user.partition('!')
print "<%s> %s" % (nick, message)
def _send_message(self, msg, target, nick=None):
if nick:
msg = '%s, %s' % (nick, msg)
self.msg(target, msg)
print "<%s> %s" % (self.nickname, msg)
class TwitchFactory(protocol.ReconnectingClientFactory):
protocol = TwitchProtocol
channels = config["channels"]
if __name__ == '__main__':
reactor.connectTCP(HOST, PORT, TwitchFactory())
log.startLogging(stdout)
reactor.run()
elif __name__ == '__builtin__':
application = service.Application('Twitch')
ircService = internet.TCPClient(HOST, PORT, TwitchFactory())
ircService.setServiceParent(application)
但是当它发现抽搐电视频道播出时会出错。

要求json模块解码不是JSON数据的内容。
2013-12-08 22:42:12+0000 [-] File "irctwitch.py", line 60, in getTwitchStatus

你调用.json()的东西是无效的JSON。尝试在调用requests.get()之前打印出.json()的结果，看看会发生什么。
