如何编写非阻塞代码使用PyQT5上传到PyDrive的谷歌驱动器？

pip install PyQt5 PyDrive

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QFileDialog, QVBoxLayout, QWidget
from PyQt5.QtCore import QThread, pyqtSignal
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

# 工作线程类
class UploadThread(QThread):
    upload_finished = pyqtSignal(str)  # 定义一个信号，用于通知上传完成

    def __init__(self, file_path):
        super().__init__()
        self.file_path = file_path

    def run(self):
        gauth = GoogleAuth()
        gauth.LocalWebserverAuth()  # 这里会弹出一个浏览器窗口让你登录谷歌账号
        drive = GoogleDrive(gauth)

        file1 = drive.CreateFile({'title': self.file_path.split('/')[-1]})
        file1.Upload()
        self.upload_finished.emit(self.file_path)  # 发射信号，通知上传完成

# 主窗口类
class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.setWindowTitle('PyQT5 PyDrive Upload')
        self.setGeometry(100, 100, 300, 200)

        layout = QVBoxLayout()

        self.upload_button = QPushButton('选择文件并上传')
        self.upload_button.clicked.connect(self.select_and_upload_file)
        layout.addWidget(self.upload_button)

        container = QWidget()
        container.setLayout(layout)
        self.setCentralWidget(container)

    def select_and_upload_file(self):
        options = QFileDialog.Options()
        file_path, _ = QFileDialog.getOpenFileName(self, "QFileDialog.getOpenFileName()", "", "All Files (*);;Python Files (*.py)", options=options)
        if file_path:
            self.upload_thread = UploadThread(file_path)
            self.upload_thread.upload_finished.connect(self.upload_complete)
            self.upload_thread.start()

    def upload_complete(self, file_path):
        print(f'文件 {file_path} 已上传到谷歌驱动器。')

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