Question

我刚为 Python 2.7.8 安装 pywinauto-0.4.2 （在Windows 7 64位计算机上）。我正在尝试pywinauto

上引用的一个例子

程序的源代码 SaveFromFirefox.py （在上面的网址中给出）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该文件时，它会打开firefox浏览器，然后打开＆＃34;另存为＆＃34;对话框但是没有按下＆＃34;保存＆＃34;按钮。

相反，它会给出以下错误消息：

出了什么问题？

Answer 1

只需更改

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。

与WinXP相比，Win7中的标准打开/保存对话框改变了它无法正常工作的主要原因。可能这个例子几年前写在WinXP上。

使用Python中的pywinauto保存Firefox网页时出错
