assistance dépannage d'une erreur python/cherrypy

Question

import cherrypy 
import os 

PORT = 8080 

class intelServ: 
    def index(self, botkey = None, userkey = None, network = None, user = None, channel = None, msg = None, step = None, **args): 

     # If any necessary parameters are missing, the bot should fail silently. 
     #if not botkey or not userkey or not network or not user or not channel or not msg: 
     # return 'failing' 

     chatLog = Chat() 
     chatLog.genLogfile(botkey, userkey) 

     return "You said: " + msg 
    index.exposed = True 


class Chat: 
    def genLogfile(self, botkey, userkey): 
     botHome = os.path.join(os.curdir, botkey) 
     chatLog = os.path.join(botHome, userkey) 
     print botHome 
     print chatLog 

     # check if bot has a home, if not make one 
     if not os.path.exists(botHome): 
      os.mkdir(botHome) 

     # check if communication is already in progress, if not start it. 
     if not os.path.exists(chatLog): 
      FILE = open(chatLog, "w") 
      FILE.close() 
      FILE = open(chatLog+".step","w") 
      FILE.close() 

# configure and start our cherrypy server 
cherrypy.config.update({'server.socket_port': PORT, 'server.socket_host': '0.0.0.0'}) 
cherrypy.quickstart(intelServ()) 

Ce code renvoie le retraçage suivant et je ne peux pas comprendre pourquoi:

Answer 1

Il semble que le paramètre botkey tel qu'il est fourni à intelServ.index() est Aucun (d'où le 'NoneType'). Vous devriez décommenter votre code de validation d'entrée.
