多人在线聊天室，可私聊可发表情包哟~

这学期我们网络编程这门课主要是Window Socket，并且还是用我们没学过C++实现的，不过值得庆幸的是老师上课讲的很仔细，并且他讲课主要是讲思想，实现思路，最后老师没有限制我们课程设计使用的语言。权衡了一下，我使用Python实现了多人在线聊天的聊天室。

这个聊天室的主要功能是：

1、多人聊天——群聊

2、私聊

3、发表情包

有种仿QQ和微信聊天的感觉，但是界面不太美观，功能没那么强大，但是用作网络编程的课程设计大作业还是OK的......

这个小项目首先是在b站看的教学视频，这个教程就只实现多人聊天的功能，后面我要在这个基础上实现了私聊、发表情的功能，源码我会放到文章的最后，有需要的可以下载......

这篇文章主要是讲和教程不一样的地方，详细可以看一下的教学视频，或是自己下载源码学习.....

一、服务端

服务端主要是在处理客户端请求的死循环中，添加了一个判断，判断是否要进入私聊的聊天模式

    def request_handle(self, client_sock):"""处理客户端请求"""while True:"""1、接收客户端请求"""recv_data = client_sock.recv_data()if not recv_data:  # 如果收到空字符串 就表示结束聊天self.remove_offline_user(client_sock)client_sock.close()breakprint("客户端发送的请求信息：%s" % recv_data)"""2、解析客户端请求"""parser_data = self.parser_request_text(recv_data)print("解析过的数据为：%s" % parser_data)"""3、判断请求类型,调用请求对应的处理函数"""handle_function = self.request_handle_function.get(parser_data["request_id"])if handle_function:handle_function(client_sock, parser_data)#处理聊天请求def request_chat_handle(self, client_sock, request_data):print("正在处理聊天请求~")username = request_data['username']messages = request_data['messages']chat = request_data['chat']nickname = self.clients[username]['nickname']msg = ResponseProtocol.response_chat(nickname, messages, str(self.users), chat)if chat == '------------------群聊------------------':for u_name, info in self.clients.items():if username == u_name:continueinfo['sock'].send_data(msg)else:for u_name, info in self.clients.items():if username == u_name:continueelif chat == info['nickname']:info['sock'].send_data(msg)

二、客户端

客户端的代码有较大的变化

首先是图形界面：

聊天界面的主要变化

    def append_message(self, sender, messages, chat):"""追加聊天内容到chat_text_area"""send_time = strftime("%Y-%m-%d %H:%M:%S", localtime(time()))send_info = "%s: %s\n" % (sender, send_time)# 判断是不是表情  如果字典里有则贴图if messages in self.dic:if chat == '------------------群聊------------------':self.children['chat_text_area'].insert(END, send_info, 'green')  # END将信息加在最后一行self.children['chat_text_area'].image_create(END, image=self.dic[messages])self.children['chat_text_area'].insert(END, "\n")self.children['chat_text_area'].see(END)else:self.children['chat_text_area'].insert(END, send_info, 'blue')  # END将信息加在最后一行self.children['chat_text_area'].image_create(END, image=self.dic[messages])self.children['chat_text_area'].insert(END, "\n")self.children['chat_text_area'].see(END)else:if chat == '------------------群聊------------------':self.children['chat_text_area'].insert(END, send_info, 'green')  # END将信息加在最后一行self.children['chat_text_area'].insert(END, "  " + messages + "\n")self.children['chat_text_area'].see(END)else:  # 显示私聊self.children['chat_text_area'].insert(END, send_info, 'blue')  # END将信息加在最后一行self.children['chat_text_area'].insert(END, "  " + messages + "\n")self.children['chat_text_area'].see(END)  # 显示在最后

登录界面：
