python mechanize - 从触发文件下载的 aspnetForm submitControl 检索文件

Question

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

我得到了这个输出:

    Submitting...

    Response...

似乎我非常接近......注意内容类型:application/vnd.ms-excel

我只是不知道下一步该做什么。我的文件在哪里，如何获取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() 获取 response() 的方法/属性列表，然后尝试了几个方法...

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()

我得到了这个输出...

dir(br.response())

__copy__
__doc__
__getattr__
__init__
__iter__
__module__
__repr__
__setattr__
_headers
_seek_wrapper__cache
_seek_wrapper__have_readline
_seek_wrapper__is_closed_state
_seek_wrapper__pos
_seek_wrapper__read_complete_state
close
get_data
geturl
info
invariant
next
read
readline
readlines
seek
set_data
tell
wrapped
xreadlines

response info...

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。

Answer 1

# fill out the form
response = br.submit()
fileobj = open('filename', 'w+')
fileobj.write(response.read())
fileobj.close()
