关于lua中事件监听，多次请求网络的问题

注意：所用的函数库是quick-cocos2d-x-2.2.1-rc

这里有一个GCommandEventManager.lua

GCommandEventManager={}
function GCommandEventManager.init()
require(cc.PACKAGE_NAME .. ".api.EventProtocol").extend(GCommandEventManager)
end

-- function GCommandEventManager.addEL(eventName,callBack)
-- 	GCommandEventManager:addEventListener(eventName,callBack)
-- end

return GCommandEventManager
-- --------------------------提供以下接口------------------------
-- EventProxy:addEventListener(eventName, listener, data)
-- EventProxy:removeEventListener(eventName, key1, key2)
-- EventProxy:removeAllEventListenersForEvent(eventName)

-- EventProxy:removeAllEventListeners()

有如下代码，对于匿名的函数function必须调用GCommandEventManager:removeAllEventListenersForEvent("Story_doTowerStoryPre")。才不会请求多次

GCommandEventManager:addEventListener("Story_doTowerStoryPre",function(params)
GCommandEventManager:removeAllEventListenersForEvent("Story_doTowerStoryPre")
if params.data.code == 0 then
local Storykey = params.data.ret.storykey.."1"
b_win = true
local encodestr = crypto.md5(Storykey)
GMissionCommand.TowerStoryResult(encodestr)
print("请求了一次")
GCommandEventManager:addEventListener("Story_doTowerStory",GTowerLayer.FightResult)
end
end)

而对于有名函数。如下

GCommandEventManager:removeEventListener("Story_doTowerStory",GTowerLayer.FightResult)

则必须调用GTowerLayer.FightResult这个函数才能移除事件监听
