python socket通信并相互输出在gui窗口上

好的，这里提供一个使用PyQt5实现socket通信并显示在GUI窗口上的示例代码。

服务端代码：

import socket
import threading

HOST = 'localhost'
PORT = 8888

class ServerThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.server_socket.bind((HOST, PORT))
        self.server_socket.listen(1)
        print('Waiting for client connection...')
        
    def run(self):
        while True:
            conn, addr = self.server_socket.accept()
            print('Connected by', addr)
            client_thread = ClientThread(conn, addr)
            client_thread.start()

class ClientThread(threading.Thread):
    def __init__(self, conn, addr):
        threading.Thread.__init__(self)
        self.conn = conn
        self.addr = addr
        
    def run(self):
        while True:
            data = self.conn.recv(1024)
            if not data:
                break
            print('Received:', data.decode())
            self.conn.sendall(data)
        
        self.conn.close()
        print('Connection closed by', self.addr)

server_thread = ServerThread()
server_thread.start()

客户端代码：

import sys
import socket
from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QApplication, QWidget, QTextEdit, QLineEdit, QVBoxLayout

HOST = 'localhost'
PORT = 8888

class ClientWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()
        self.connectServer()
        
    def initUI(self):
        self.setWindowTitle('Socket Communication')
        self.setGeometry(100, 100, 400, 300)
        
        self.text_edit = QTextEdit()
        self.text_edit.setReadOnly(True)
        self.text_edit.setFocusPolicy(Qt.NoFocus)
        
        self.line_edit = QLineEdit()
        self.line_edit.returnPressed.connect(self.sendMsg)
        
        layout = QVBoxLayout()
        layout.addWidget(self.text_edit)
        layout.addWidget(self.line_edit)
        self.setLayout(layout)
        
    def connectServer(self):
        self.client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.client_socket.connect((HOST, PORT))
        self.recvThread = RecvThread(self.client_socket)
        self.recvThread.recvSignal.connect(self.recvMsg)
        self.recvThread.start()
        
    def sendMsg(self):
        msg = self.line_edit.text().strip()
        if msg:
            self.client_socket.sendall(msg.encode())
            self.text_edit.append('Client: ' + msg)
            self.line_edit.clear()
        
    def recvMsg(self, msg):
        self.text_edit.append('Server: ' + msg.decode())

class RecvThread(threading.Thread):
    recvSignal = pyqtSignal(bytes)
    
    def __init__(self, conn):
        threading.Thread.__init__(self)
        self.conn = conn
        
    def run(self):
        while True:
            data = self.conn.recv(1024)
            if not data:
                break
            self.recvSignal.emit(data)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = ClientWidget()
    widget.show()
    sys.exit(app.exec_())

运行服务端代码，然后运行客户端代码，即可在GUI窗口中输入消息并看到服务器的响应。注意，这里使用了PyQt5的信号槽机制来在接收线程中将消息传递给主线程进行显示。
