如何从Qt5图形用户界面打开http.server而不阻塞图形用户界面？

import sys
import threading
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
from http.server import HTTPServer, BaseHTTPRequestHandler

class MyRequestHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)
        self.send_header('Content-type', 'text/html')
        self.end_headers()
        self.wfile.write(b'Hello, World!')

class ServerThread(threading.Thread):
    def run(self):
        server_address = ('', 8000)
        httpd = HTTPServer(server_address, MyRequestHandler)
        httpd.serve_forever()

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('Qt HTTP Server Example')
        self.setGeometry(100, 100, 300, 200)

        button = QPushButton('Start Server', self)
        button.setGeometry(100, 80, 100, 30)
        button.clicked.connect(self.start_server)

    def start_server(self):
        server_thread = ServerThread()
        server_thread.start()

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