python mechanize - 從aspnetForm中檢索文件submitControl觸發文件下載

Question

如何使用python mechanize從aspnetForm submitControl中檢索文件，當我不知道文件URL或文件名時觸發Excel文件下載？

網站與Excel文件的URL：http://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01

我試圖獲得通過打印Excel的「按鈕」下載的文件。

到目前爲止，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 

，我得到這樣的輸出：

Submitting... 

    Response...

看來我很近...注意的內容類型：應用程序/ vnd.ms - Excel中

我只是不知道接下來該做什麼。我的文件在哪裏，以及如何獲取指向它的指針並將其保存在本地以供以後訪問？

更新：

我使用DIR（）來獲取的方法列表/屬性響應（），然後嘗試了幾個方法...

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() 

，我得到這個輸出...

dir(br.response())

__doc__ 
__getattr__ 
__init__ 
__iter__ 
__module__ 
__repr__ 
__setattr__

_seek_wrapper__is_closed_state 
_seek_wrapper__pos

我想我已經在我的br.response中有這個文件。我只是不知道如何提取它！請幫忙。

Answer 1

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