为此应用添加Qt套接字代码，以启用两台PC之间的聊天

Question

任何人都可以帮我这个代码吗？如何在此程序中添加P2P聊天代码？ 我希望能够通过LAN在两台PC之间聊天

最后解决了这个问题。客户端就在这里

from PyQt5 import QtCore, QtWidgets, QtWidgets, QtNetwork

class Client(QtWidgets.QDialog):

def __init__(self, parent=None):
    super(Client, self).__init__(parent)

    self.main_text = QtWidgets.QTextEdit(self)
    self.main_text.setReadOnly(True)
    self.send_box = QtWidgets.QLineEdit(self)
    self.send_button = QtWidgets.QPushButton("Send", self)
    self.browse_btn = QtWidgets.QPushButton("Browse", self)
    # EVENT FOR SEND BUTTON
    self.send_button.clicked.connect(self.sendData)

    self.server_ip = QtWidgets.QLineEdit(self)
    self.server_ip.setPlaceholderText("IP address")
    self.port_address = QtWidgets.QLineEdit(self)
    self.port_address.setPlaceholderText("port")

    self.userName = QtWidgets.QLineEdit(self)
    self.userName.setPlaceholderText("username")

    self.connectButton = QtWidgets.QPushButton("Connect",self)
    #Connect Button EVENT
    self.connectButton.clicked.connect(self.connection)
    self.connectButton.setDefault(True)

    self.setGeometry(400,50,500,600)
    self.main_text.setGeometry(25,50,450,400)
    self.send_box.setGeometry(25,470,450,40)
    self.send_button.setGeometry(385,520,90,30)
    self.browse_btn.setGeometry(25,520,100,30)
    self.server_ip.setGeometry(150,10,130,25)
    self.port_address.setGeometry(300,10,70,25)
    self.connectButton.setGeometry(385,10,90,25)
    self.userName.setGeometry(25,10,120,25)


    #NetworkInput
    self.socket = QtNetwork.QTcpSocket(self)
    self.socket.readyRead.connect(self.readData)
    self.socket.error.connect(self.displayError)

def closeEvent(self, event):
    self.socket.disconnectFromHost()

def connection(self):
    self.socket.connectToHost(self.server_ip.text(), int(self.port_address.text()))
    if self.socket.waitForConnected(1000):
        self.user = self.userName.text()
        self.send("login %s" % self.user)
        self.connectButton.setEnabled(False)
        self.send_button.setDefault(True)
        self.send_box.setFocus()
        #self.setWindowTitle("<%s>" % self.user)
def readData(self):
    message = self.socket.readLine().data().decode("utf-8")
    self.main_text.append(message)

def send(self, message):
    self.socket.write(message.encode("utf-8"))

def sendData(self):
    message = "say %s" % (self.send_box.text())
    self.send(message)
    self.send_box.clear()
    self.send_box.setFocus()

def displayError(self):
    QtWidgets.QMessageBox.information(self, "Connection", "Connection error")


if __name__ == "__main__":
   import sys
   app = QtWidgets.QApplication(sys.argv)
   client = Client()
   sys.exit(client.exec_())
