当我不知道文件 URL 或文件名时，如何使用 python mechanize 从触发 Excel 文件下载的 aspnetForm submitControl 检索文件？
带有 Excel 文件的站点 URL： http ://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01
我正在尝试通过“打印 Excel”“按钮”下载文件。
到目前为止，我有：
r = br.open('http://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01')
html = r.read()
# Show the html title
print br.title()
# Show the available forms
for f in br.forms():
print f
br.select_form('aspnetForm')
print '\n\nSubmitting...\n'
br.submit("ctl00$ContentPlaceHolder1$btnExtractSched")
print 'Response...\n'
print br.response().info()
print br.response().read
print 'still alive...\n'
for prop, value in vars(br.response()).iteritems():
print 'Property:', prop, ', Value: ', value
print 'myfile...\n'
myfile = br.response().read
我得到这个输出：

似乎我很接近...注意内容类型：application/vnd.ms-excel
我只是不知道下一步该怎么做。我的文件在哪里，如何获得指向它的指针并将其保存在本地以供以后访问？
更新：
我使用 dir() 来获取 response() 的方法/属性列表，然后尝试了几种方法......
print '\ndir(br.response())\n'
for each in dir(br.response()):
print each
print '\nresponse info...\n'
print br.response().info()
print '\nresponse geturl\n'
print br.response().geturl()
我得到这个输出......
dir(br.response())

__doc__
__getattr__
__init__
__iter__
__module__
__repr__
__setattr__
_headers
_seek_wrapper__cache
_seek_wrapper__have_readline

_seek_wrapper__pos

我想我的 br.response 中已经有了这个文件。我只是不知道如何提取它！请帮忙。
