javascript - autobahn python で json を送信する

Question

sendMessage を使用して url から json コンテンツをクライアントに送信しようとしています。

def broadcast(self):
  response = urllib2.urlopen('http://localhost:8001/json?as_text=1')
  data = json.load(response)

  for c in self.clients:
     c.sendMessage(data)

エラーが発生します

File "myServer.py", line 63, in broadcast
c.sendMessage(data)
