python - 在 Python 中使用 pywinauto 保存 Firefox 网页时出错

Question

我刚刚为 Python 2.7.8 安装了 pywinauto-0.4.2(在 Windows 7 64 位机器上)。我正在尝试在 pywinauto 上引用的示例

SaveFromFirefox.py 程序的源代码(在上面的 URL 中给出)是:

from pywinauto.application import Application
import sys
import time
import os.path

if len(sys.argv) < 2:
    print "please specify a web address to download"
    sys.exit()

web_addresss = sys.argv[1]

if len(sys.argv) > 2:
    outputfilename = sys.argv[2]
else:
    outputfilename = web_addresss
    outputfilename = outputfilename.replace('/', '')
    outputfilename = outputfilename.replace('\\', '')
    outputfilename = outputfilename.replace(':', '')


# start IE with a start URL of what was passed in
app = Application().start_(
    r"c:\program files\Mozilla Firefox\Firefox.exe %s"% web_addresss)

# some pages are slow to open - so wait some seconds
time.sleep(4)

# mozilla is one of thos applications that use existing windows
# if they exist (at least on my machine!)
# so if we cannot find any window for that process
#  - find the actual process
#  - connect to it
if app.windows_():
    mozilla =  app.window_(title_re = ".*Mozilla Firefox")

else:
    app = Application().connect_(title_re = ".*Mozilla Firefox")
    mozilla = app.window_(title_re = ".*Mozilla Firefox")

# ie doesn't define it's menus as Menu's but actually as a toolbar!
print "No Menu's in FireFox:", mozilla.MenuItems()

# File -> Save As
mozilla.TypeKeys("%FA")
#ie.Toolbar3.PressButton("File")
app.SaveAs.FileNameEdit.SetEditText(outputfilename)

app.SaveAs.Save.CloseClick()

# if asked to overwrite say yes
if app.SaveAs.Yes.Exists():
    app.SaveAs.Yes.CloseClick()

print "saved:", outputfilename

# File close tab or close
#(Firefox makes it easy for us having the same shortcut for both!
mozilla.TypeKeys("%FC")

当我尝试在命令提示符下执行文件时，它打开了 firefox 浏览器，然后打开了“另存为”对话框，但没有按下“保存”按钮。

相反，它给出了以下错误信息:

出了什么问题？

Answer 1

改变

app.SaveAs.FileNameEdit.SetEditText(outputfilename)

到

app.SaveAs.Edit.SetEditText(outputfilename)

它适用于 Firefox 34.0.5。我也改变了路径

app = application.Application().start_(
r"C:\Program Files (x86)\Mozilla Firefox\firefox.exe %s"% web_addresss)

这是在 Win7 x64 + Python 2.6.6(32 位)上。

它不起作用的主要原因是与 WinXP 相比，Win7 中的标准打开/保存对话框发生了变化。可能这个例子是几年前在 WinXP 上写的。
