我正在創建一個python應用程序。鏈接到 ui.py 和 app.py： https://gist.github.com/tbhaxor/f68387d49bc59b2bdd025512c17a2534app.pyfrom PyQt5 import QtWidgets, QtCorefrom ui import Ui_MainWindowfrom selenium.webdriver.chrome.webdriver import WebDriverfrom selenium.webdriver.chrome.options import Optionsimport osimport tracebackimport pickle as pklfrom pathlib import Pathfrom typing import List, Dict, Unionclass Application(Ui_MainWindow): def __init__(self, window: QtWidgets.QMainWindow, driver: WebDriver = None): self.parent = window self.driver = driver self.setupUi(window) self.retranslateUi(window) qtRectangle = window.frameGeometry() centerPoint = QtWidgets.QDesktopWidget().availableGeometry().center() qtRectangle.moveCenter(centerPoint) window.move(qtRectangle.topLeft()) self.__makeHandlers() self.file = os.path.join(Path.home(), "_linkedin.db") self.db: Dict[str, str] = { "api": "", "email": "", "password": "", "sent": [], "delay": 10, "template": "" } self.search_limit.valueChanged.connect(print) pass def __makeHandlers(self): self.search_limit.valueChanged.connect(print) pass def handle_fetch(self): pass def __login(self): driver.get("https://www.linkedin.com/login") # /html/body/div[1]/main/div/form/div[1]/input # /html/body/div[1]/main/div/form/div[2]/input # /html/body/div[1]/main/div/form/div[4]/button pass passif __name__ == "__main__": import sys try: opts = Options() opts.headless = os.environ.get("PYDBG", "0") != "1" driver: WebDriver = WebDriver(options=opts) app = QtWidgets.QApplication(sys.argv)

問題很簡單：通過執行 setupUi 方法，您正在創建內部小部件，如果第二次運行 setupUi 會發生什么情況？好吧，舊的小部件被刪除并創建了新的小部件。在你的情況下，你首先在應用程序的構造函數中調用了 setupUi，并且在 之后再次調用它，在第一次調用時，你建立了連接，然后將其刪除，因此連接已斷開。解決方案：只需調用安裝程序Ui一次。也沒有必要調用重譯Ui，因為安裝Ui已經這樣做了。ui = Application(MainWindow)
class Application(Ui_MainWindow):
def __init__(self,
window: QtWidgets.QMainWindow,
driver: WebDriver = None):
self.parent = window
self.driver = driver
self.setupUi(window)
# self.retranslateUi(window) # remove this line
qtRectangle = window.frameGeometry()
# ...
if __name__ == "__main__":
import sys
try:
opts = Options()
opts.headless = os.environ.get("PYDBG", "0") != "1"
driver: WebDriver = WebDriver(options=opts)
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Application(MainWindow)
# ui.setupUi(MainWindow) # remove this line
MainWindow.show()
app.exec_()
except Exception:
print(traceback.format_exc())
finally:
driver.quit()
