Python JSON 디코더 오류

Question

현재 지정된 트 위치 TV 채널이 공중에 떠있을 때 IRC로 브로드 캐스트하는 스크립트를 사용하고 있습니다.

하지만 온라인에 연결될 때 어떤 이유로 계속 오류가 발생합니다. 그러나 오프라인이되면 완벽하게 정상적으로 작동합니다.

파이썬 코드 :

# 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"

from HTMLParser import HTMLParser 
from sys import stdout 

from twisted.internet import reactor, task, protocol 
from twisted.python import log 
from twisted.words.protocols import irc 
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 
    status = False 


    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 
      viewers = viewers + "s" if not " 1 view" in viewers else 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) 

하지만 그것은 트 위치 TV 채널이 오류를 줄 것이다 공기에있는 것을 발견 할 때.

어떻게이 오류를 해결할 수 있습니까?

은 json 모듈은 JSON 데이터 아니었다 뭔가를 디코딩하도록 요청 받았다.

2013-12-08 22:42:12+0000 [-] File "irctwitch.py", line 60, in getTwitchStatus 
2013-12-08 22:42:12+0000 [-]  data = requests.get("http://api.justin.tv/api/stream/list.json?channel=" + channel).json() 

.json()을 (를) 호출 한 것은 유효한 JSON이 아닙니다. .json()에 전화하기 전에 requests.get()의 결과를 인쇄 해보고 무슨 일이 일어나는 지보십시오.
