一、PyQt6 实现的界面 二、TCP server代码的修改示意 界面提供网络参数的配置以及提供人机交互过程中的数据获取和显示。
1、把上面的server代码封装成两个部分
A、class Server 负责接受UI界面的参数并通过信号与后台线程通讯
B、class ServerSocketReceiveThread 封装了 server socket 接收数据的行为并提供信号与Server交换数据
如果在UI界面调用while语句接收socket数据会导致界面卡死。 所以使用新线程运行socket接收数据的操作通过信号传递给Server中定义的方法实现数据传递。
下图是原来的代码与修改后的代码部分映射的关系
2、Server的完整代码 class Server:def __init__(self, ui, server_ip, server_hostname, server_port):self.ui ui # 主界面self.ip server_ip # 服务器ip地址self.port server_port # 服务器端口号self.serverName server_hostname # 显示名称self.is_running False # 是否已经启动self.socket None # socketself.socketThread None # 新的 socket receive 线程self.start()def start(self):if not self.is_running:self.is_running Trueself.socket socket.socket(socket.AF_INET, socket.SOCK_STREAM)self.socket.bind((self.ip, self.port)) # 绑定IP与端口self.socket.listen(1) # 设定最大连接数self.startSocketReceiveThread()def stop(self):try:if self.is_running:self.is_running Falseif self.socketThread.is_running:self.socketThread.stop()except Exception as e:print(e)def startSocketReceiveThread(self):self.socketThread ServerSocketReceiveThread(self.socket)self.socketThread.clientConnection.connect(self.socket_client_connect_trigger)self.socketThread.receivedClientData.connect(self.show_client_message)self.socketThread.serverStatus.connect(self.server_status_trigger)self.socketThread.start()def server_status_trigger(self, status):self.ui.statusbar.showMessage(status)def socket_client_connect_trigger(self, state):if state connect:self.ui.statusbar.showMessage(客户端已经连接。)else:self.ui.statusbar.showMessage(客户端已经断开。)def show_client_message(self, message):self.ui.textEdit.append(客户端: message)def send_message_to_client(self, message):if self.is_running:self.ui.textEdit.append(self.serverName : message)self.socketThread.send_data_to_client(message)3、ServerSocketReceiveThread 完整代码 class ServerSocketReceiveThread(QThread):clientConnection: pyqtSignal pyqtSignal(str) # 向主线程发送连接状态标志receivedClientData: pyqtSignal pyqtSignal(str) # 向主线程发送接受到客户端的数据serverStatus: pyqtSignal pyqtSignal(str) # 向主线程发送服务器状态def __init__(self, serverSocket):super(ServerSocketReceiveThread, self).__init__()self.serverSocket serverSocketself.clientSocket Noneself.addr Noneself.is_running Truedef run(self):self.serverStatus.emit(服务已经启动等待客户端的连接......)self.clientSocket, self.addr self.serverSocket.accept() # 接受客户端的连接self.emitConnectEvent(connect) # 发送通知到主界面self.startReceiveData()def startReceiveData(self):while self.is_running:try:data self.clientSocket.recv(1024).decode(utf-8) if not data:self.emitConnectEvent(disconnect) # 发送通知到主界面breakself.sendClientDataToUi(data)except ConnectionResetError as reason:self.sendClientDataToUi(已经离开对话。)self.is_running Falseself.emitConnectEvent(disconnect) # 发送通知到主界面breakself.clientSocket.close()self.serverSocket.close()self.serverStatus.emit(服务已经关闭。)def send_data_to_client(self, message):try:self.clientSocket.send(message.encode(utf-8))except Exception as reason:print(发送失败原因 , reason)def stop(self):if self.is_running:self.is_running Falsedef emitConnectEvent(self, state):self.clientConnection.emit(state)def sendClientDataToUi(self, message):self.receivedClientData.emit(message)三、TCP Client 代码也是同样封装为两部分
1、class Client完整代码 class Client:def __init__(self, ui, ip, clientName, port):self.ui uiself.ip ipself.hostName clientNameself.port portself.socket Noneself.socketThread Noneself.connect_server()def connect_server(self):self.socket socket.socket(socket.AF_INET, socket.SOCK_STREAM)self.socketThread ClientSocketReceiveThread(self.socket)self.socketThread.receivedServerData.connect(self.update_ui_chat_content)if self.connect_success(self.ip, self.port):self.socketThread.start()def update_ui_chat_content(self, serverMessage):self.ui.textEdit_2.append(服务端: serverMessage)def stop(self):self.socketThread.stop()def send_data(self, sentence):self.ui.textEdit_2.append(self.hostName : sentence)self.socket.send(sentence.encode())def connect_success(self, ip, port):try:self.socket.connect((ip, port))return Trueexcept Exception as reason:print(reason)return False2、class ClientSocketReceiveThread完整代码 class ClientSocketReceiveThread(QThread):receivedServerData: pyqtSignal pyqtSignal(str) # 向主线程发送接受到客户端的数据def __init__(self, clientSocket):super(ClientSocketReceiveThread, self).__init__()self.clientSocket clientSocketself.is_running Truedef stop(self):self.is_running Falseself.clientSocket.close()def run(self):while self.is_running:try:msg self.clientSocket.recv(1024).decode(utf-8) # 接受服务端消息if not msg:breakself.receivedServerData.emit(msg)except Exception as reason:print(reason)breakself.stop()self.receivedServerData.emit(已经与服务端断开。)
