客户端：
1.既然脚本是让别人用的，怎么说也得有个界面，（虽然很low）
'''DenyManager.py调用客户端与客户端界面'''from DenyClient import *from DenyGui import *if __name__ == '__main__': clientConncet = DenyHttpClient() clientGui = DenyHttpGui()
2.客户端的界面很简单，签到还没写，（构思中…）其实能用的就一个比赛开始的Button
这是后台跑的数据
这个连接服务器的messageBox为了改变比赛开始Button的状态为不可点击
检查版本信息，在确定开始比赛之前检查版本信息，版本不对，更新吧（下个新版的就好了）
之后，开始比赛！
