python - pywinauto:从 MS Edge Canary 地址栏中获取 URL

Question

我使用 pywinauto 从 Chrome 浏览器的地址栏中获取 URL 地址没有任何问题。我“应该”能够以相同的方式从 Microsoft Edge Canary 浏览器中获取 URL。但是，似乎有些东西阻止了 pywinauto 抓取 URL；导致它超时并产生后续异常。
代码:

from pywinauto import Application

app = Application(backend='uia')
app.connect(title_re=".*Microsoft​ Edge.*", found_index=0)

captionsearch = Application().connect(title_re=".*Microsoft​ Edge.*", found_index=0)
caption = captionsearch.windows(title_re=".*Microsoft​ Edge.*", found_index=0)
caption = str(caption)

dlg = app.top_window()
url = dlg.child_window(title="Address and search bar", control_type="Edit").get_value()

错误:

Traceback (most recent call last):
  File "C:\Users\micha\AppData\Local\Programs\Python\Python37\lib\site-packages\pywinauto\application.py", line 258, in __resolve_control
    criteria)
  File "C:\Users\micha\AppData\Local\Programs\Python\Python37\lib\site-packages\pywinauto\timings.py", line 458, in wait_until_passes    
    raise err
pywinauto.timings.TimeoutError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "d:/OneDrive/Dev/Projects/Python/Share-URL-Edge.py", line 42, in <module>
    url = dlg.child_window(title="Address and search bar", control_type="Edit").get_value()
  File "C:\Users\micha\AppData\Local\Programs\Python\Python37\lib\site-packages\pywinauto\application.py", line 379, in __getattribute__
    ctrls = self.__resolve_control(self.criteria)

    func_val = func(*args, **kwargs)
  File "C:\Users\micha\AppData\Local\Programs\Python\Python37\lib\site-packages\pywinauto\application.py", line 222, in __get_ctrl
    ctrl = self.backend.generic_wrapper_class(findwindows.find_element(**ctrl_criteria))
  File "C:\Users\micha\AppData\Local\Programs\Python\Python37\lib\site-packages\pywinauto\findwindows.py", line 87, in find_element
    raise ElementNotFoundError(kwargs)
pywinauto.findwindows.ElementNotFoundError: {'title': 'Address and search bar', 'control_type': 'Edit', 'top_level_only': False, 'parent': <uia_element_info.UIAElementInfo - 'pywinauto: URL from MS Edge Canary Address Bar - Stack Overflow and 1 more pare page - Personal - Microsoft​ Edge', Chrome_WidgetWin_1, 1510144>, 'backend': 'uia'}

我能够通过更改以下行来使其工作:

url = dlg.child_window(title="Address and search bar", control_type="Edit").get_value()

到:

url = dlg.child_window(control_type="Edit", found_index=0).get_value()
if url == "":
    url = dlg.child_window(control_type="Edit", found_index=1).get_value()
if url == "":
    url = dlg.child_window(control_type="Edit", found_index=2).get_value()
if url == "":
    url = dlg.child_window(control_type="Edit", found_index=3).get_value()

然而，这是一种可怕的方法。此外，它在某些情况下不起作用。我真的很感激有 pywinauto 经验的人可以帮助我以正确的方式做到这一点。
PS:我没有太多运气使用inspect.exe来解决这个问题。据我所知，Edge Canary 和 Google Chrome 都使用元素名称 Address and search bar .但是，它不适用于 Edge Canary 浏览器。

无论站点是否安全，此代码似乎都有效:

app = pywinauto.Application(backend='uia')
app.connect(title_re=".*Microsoft​ Edge.*", found_index=0)
dlg = app.top_window()
wrapper = dlg.child_window(title="App bar", control_type="ToolBar")
url = wrapper.descendants(control_type='Edit')[0]
print(url.get_value())

即使此修补程序有效，最好直接转到“地址和搜索栏”元素。如果这不起作用，您应该在 https://github.com/pywinauto/pywinauto/issues 中报告此问题
