我正在使用一个脚本，当一个指定的Twitch电视频道播放时，广播到IRC。Python JSON解码器错误
但由于某种原因，我不断收到错误，当它上线。但是当它脱机时，它工作得很好。
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"
import requests

from twisted.application import internet, service
with open('config.yml') as f:
config = yaml.load(f.read())
HOST, PORT = config['host'], config['port']
def munge(inp):
# Prevents highlight notification in most clients
return inp[0] + u"\u200b" + inp[1:]
class TwitchProtocol(irc.IRCClient):
password = config["password"] if "password" in config else None
nickname = 'Twitch'
username = 'Twitch'
versionName = 'Twitch'
versionNum = 'v1.0'
realname = 'by blha303. https://gist.github.com/blha303'
loopcall = None

def signedOn(self):
for channel in self.factory.channels:
self.join(channel)
#Quakenet
self._send_message("auth %s %s" % (self.nickname, config["nspass"]), "Q")
#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):
reason.printTraceback()
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):
channel = config["twitch"]
data = requests.get("http://api.justin.tv/api/stream/list.json?channel=" + channel).json()
if data and not self.status:
fmt = "{}: {} {} ({})"
self.status = True
title = data[0]['title']
playing = ("playing " + data[0]['meta_game']) if "meta_game" in data[0] else ""
viewers = "\x033\x02Online now!\x02\x0f " + str(data[0]["channel_count"]) + " viewer"
print viewers

print viewers
h = HTMLParser()
for ch in self.factory.channels:
self._send_message(h.unescape(fmt.format(title, munge(channel), playing, viewers)), ch)
elif not data and self.status:
self.status = False
for ch in self.factory.channels:
self._send_message("%s is now offline." % channel, ch)
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，当它发现抽动电视频道上空气会给出一个错误。

我该如何解决这个错误？
Thankies， TameTimmah
停止尝试解码不是JSON的东西。 –
你应该编码'channel'，例如'urllib.urlencode（{'channel'：channel}）''。你可以使用['twisted.web.client.getPage'获取json]（https://gist.github.com/zed/7865274）。 – jfs
