我的主要目标：自动化缩放

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，当我运行上述文件时：

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>

看看在e中的Err before joinMeetingWin:之后，open_join_meeting_window()是如何不被打印或保持空白的。

同样的情况发生在get_Zoom_Main_Window()内部的get_Zoom_Main_Window()块中。

我曾在谷歌寻求帮助，但徒劳无功。

我想实现什么？

最小期望：，我可以在不破坏代码的情况下将pywinauto引发的错误发送到控制台/终端。

更多的期望:如果可能的话，可以避免代码中的try-except块。更好地实现了finding and connecting to the required window、getting hold of child_window()和switching between open windows的方式。

我的方法可能是错的。那样的话，请给我看看正确的程序。

似乎我已经想出了如何在这个print() the errors raised by pywinauto to the console/terminal without crashing my code的帮助下实现回答。

open_join_meeting_window函数-↓↓↓之前的

# after imports
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

open_join_meeting_window函数-修改后的↓↓↓

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 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

新终端日志↓↓↓

ERROR:root:Traceback (most recent call last):
  File "C:\Users\RAKTIM BHATTACHARYA.000\AppData\Local\Programs\Python\Python39\lib\site-packages\pywinauto\timings.py", line 436, in wait_until_passes
    func_val = func(*args, **kwargs)
  File "C:\Users\RAKTIM BHATTACHARYA.000\AppData\Local\Programs\Python\Python39\lib\site-packages\pywinauto\findwindows.py", line 87, in find_element  
    raise ElementNotFoundError(kwargs)
pywinauto.findwindows.ElementNotFoundError: {'title': 'hhh', 'backend': 'uia', 'visible_only': False}

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:\PythonDevelopment\Lake\zoom\getJoinMeetingWindow.py", line 14, in open_join_meeting_window
    joinMeetingWin = app.connect(title="hhh", timeout=6)

    self.process = timings.wait_until_passes(
  File "C:\Users\RAKTIM BHATTACHARYA.000\AppData\Local\Programs\Python\Python39\lib\site-packages\pywinauto\timings.py", line 458, in wait_until_passes
    raise err
pywinauto.timings.TimeoutError

[TimeoutError]:- The `Join Meeting Window` is taking longer time to appear.
Passed the try-except block!!

首先，传统的追溯是印刷的。然后，在控件流中使用pywinauto引发的错误的名称来决定要做什么。

改变这一点：

 joinMeetingWin = app.connect(title="Join Meeting", timeout=6)

通过这一点：

 joinMeetingWin = app.connect(title="Join", timeout=6)
