Python Extension: CallBack a Error to variable.

[Hanza-Ru]

Hello, I built a script based on loginExemple.as, and successfully, the
client was able to log into the room through the extension.

But, as mentioned by the documents of smartfox, can sometimes occur
drop network by the client side and for a few minutes, he
unable to connect to the server (Error: User is already
connected.).

I know where this error happens in this part of scrypt:

Code: Select all

var obj = _server.loginUser(nick, pass, chan)

if (obj.success == false){
     error = obj.error
}

then I would know how to create this part in python.
below, my extension with "TODO:".

Code: Select all

#LoginSFS Extension.
#Created by Hanza-Ru

userList = {}

def init():
    userList["Hanza-Ru"] = "J4669308"
    userList["jerry"] 	= "jerry"
    userList["smart"] 	= "fox"

def destroy():
    _server.trace("Python extension stopping")

def handleRequest(cmd, params, who, roomId, protocol):
    pass

def handleInternalEvent(evt):
    evtName = evt.getEventName()
    
    if evtName == "loginRequest":
        error = ""
        nick = evt.getParam('nick')
        password = evt.getParam('pass')
        chan = evt.getObject('chan')
        
        _server.trace("LoginResquest: " + nick + " : " + password ) #" : " + string(chan))
        if (userList[nick] != password):
            error = "Authentication failed"
            _server.trace("Authentication failed")
        else:
            _server.loginUser(nick, password, chan)
            #TODO: Traceback error on Login and put error messeger in 
            #error variable.
        #Sends Response
        r = {}
        if (error == ""):
            r['_cmd'] = "logON"
        else:
            r['_cmd'] = "logERR"
            r['_err'] = error
        _server.sendResponse(r, -1, None, chan)

You will need to catch a possible LoginException.
An example (not tested, just going by memory) could be this

Code: Select all

from it.gotoandplay.smartfoxserver.exceptions import LoginException

try:
  _server.loginUser(....)
  ...
except LoginException, message:
  #your error handling code here
