python mechanize - recupera un file da aspnetForm submitControl che attiva il download di un file

Question

Come utilizzare python mechanize per recuperare un file da un submitControl di aspnetForm che attiva un download di file di Excel quando non conosco l'URL del file o il nome del file?

URL del sito con il file Excel: http://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01

Sto cercando di ottenere il file scaricato dalla stampa di Excel pulsante ''.

Finora ho:

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 

e ottengo questo output:

Submitting... 

    Response...

Sembra Sono molto vicino ... Si noti il ​​Content-Type: application/vnd.ms-excel

Solo non so cosa fare dopo. Dov'è il mio file e come ottengo un puntatore e lo salvo localmente per un accesso successivo?

Aggiornamento:

ho usato dir() per ottenere un elenco di metodi/attributi per la risposta() e poi provato un paio di metodi ...

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() 

e ottengo questo output ...

dir(br.response()) 

__copy__ 
__doc__ 
__getattr__ 
__init__ 
__iter__ 
__module__ 
__repr__ 
__setattr__

Penso di avere già questo file nella mia risposta. Non so come estrarlo! Per favore aiuto.

Answer 1

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