设计内容：基于TCP协议编程的方式，编写程序模拟网络聊天室的运行过程。
设计要求：1.采用C/S模式，基于TCP协议编程的方式，使得各个用户通过服务器转发实现聊天的功能。
2.分为两大模块：客户端模块和服务器端模块。
3.客户端模块的主要功能：1）登陆功能：用户可以注册，然后选择服务器登入聊天室。
2）显示用户：将在线用户显示在列表中。
3）接收信息：能接收其他用户发出的信息。
4）发送信息：能发出用户要发出的信息。
4.服务器端模块的主要功能：1)检验登陆信息：检查登陆信息是否正确，并向客户端返回登陆信息，如信息正确。
就允许用户登陆。
2)显示在线状态：将该用户的状态发给各在线用户。
3)转发聊天信息：将消息转发给所有在线的用户。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
