无法使用 Python 中的“try except”块正确处理与 PYWINAUTO 相关的异常？
Cannot handle PYWINAUTO related exceptions with `try except` block in Python properly?
我的主要目标： 自动化 Zoom
我的 zoomModule.py 文件是：
import os, pywinauto
from pywinauto import Desktop
from pywinauto import findwindows
from pywinauto.application import Application
from pywinauto.keyboard import send_keys
# Create a instance of Application()
app = Application(backend="uia")
def get_Zoom_Main_Window():
"""starts and connect to zoom main window"""
zoom_exe_path = os.path.join(
os.environ["USERPROFILE"], "AppData", "Roaming", "Zoom", "bin", "Zoom.exe"
)
try:
print("starts and connect to zoom main window")
start = app.start(
zoom_exe_path,
timeout=100,
)
print("1. Zoom Started")
connected = start.connect(title="Zoom", timeout=5)
print("1. Zoom Connected")
return connected
except (
pywinauto.findwindows.ElementNotFoundError,
pywinauto.timings.TimeoutError,
) as e:
print("Err_context before 2nd try: ", e.__context__)
try:
print("Second try")
start = app.start(
zoom_exe_path,
timeout=100,
)
print("2. Zoom started")
connected = start.connect(title="Zoom - Not connected", timeout=20)
print("2. Zoom connected")
return connected
except (
pywinauto.findwindows.ElementNotFoundError,
pywinauto.timings.TimeoutError,
) as err:
print(err.__context__)
print("Unknown Problem; Check internet connection and try again!")
def open_join_meeting_window():
"""opens the Join Meeting Popup Window; returns the Join Meeting Window"""
zoomMainWin = get_Zoom_Main_Window()
zoomMainWin["Zoom"].child_window(
title="Home", control_type="TabItem"
).wrapper_object().click_input()
zoomMainWin["Zoom"].child_window(
title="Join", control_type="Button"
).wrapper_object().click_input()
try:
joinMeetingWin = app.connect(title="Join Meeting", timeout=15)
print("Connected to Join Meeting Window.")
except (findwindows.ElementNotFoundError, pywinauto.timings.TimeoutError) as e:
print("Err before joinMeetingWin: ", e)
pass
# joinMeetingWin['Join Meeting']
hek = open_join_meeting_window()
print("Haa! out of the function")
终端，当我运行上面的文件：
PS D:\PythonDevelopment\my_CLI_tools> python zoomModule.py
starts and connect to zoom main window
1. Zoom Started
1. Zoom Connected
Err before joinMeetingWin:
Haa! out of the function
PS D:\PythonDevelopment\my_CLI_tools>
查看 e 如何在 open_join_meeting_window() 中的 Err before joinMeetingWin: 之后不打印或保持空白。
get_Zoom_Main_Window()
中的 try-except 块也是如此
我曾在 google 寻求帮助，但没有成功。
我想达到什么目的？
最低期望值： 我可以 print() pywinauto 向 console/terminal 提出的错误而不会使我的代码崩溃。
更多期望： 如果可能的话，我可以在我的代码中避免 try-except 块。实施 finding and connecting to the required window、getting hold of child_window() 和 switching between open windows.
的更好方法
我的方法可能是错误的。在那种情况下，请告诉我正确的程序。
看来我已经想出如何在这个 answer 的帮助下 print() the errors raised by pywinauto to the console/terminal without crashing my code。
open_join_meeting_window函数-之前↓↓↓

open_join_meeting_window函数-修改后↓↓↓

except Exception as e:
logging.error(traceback.format_exc())
if e.__class__.__name__ == "TimeoutError":
print("[TimeoutError]:- The `Join Meeting Window` is taking longer time to appear.")
print("Passed the try-except block!!")
pass
新增终端日志↓↓↓

首先打印传统的traceback。然后 pywinauto 引发的错误名称在控制流中用于决定要做什么。
改变这个：
joinMeetingWin = app.connect(title="Join Meeting", timeout=6)
通过这个 :
joinMeetingWin = app.connect(title="Join", timeout=6)
