[google-appengine] MP3 Data Retreival

2009-11-25 Thread MajorProgamming
Is there any way to somehow fetch an external MP3 file (i.e. from
another website), and then calculate the length of the MP3 file.

I don't need the actual data of the file, I just want the length of it
(time it runs).

Keep in mind that these files can be as big as 25MB...

Thanks,

Hello,
Good question guaranteed to depend on host config (could be custom or
fake descriptions) while one mentioned way is use HTTP HEAD
#Call HTTP HEAD in Python
import httplib
conn=httplib.HTTPConnection(www.abc.com)
conn.request(HEAD, /dir/file1.mp3)
res=conn.getresponse()
fileSize=res.getheader('content-length')
#or res.getheaders() for all headers
conn.close()
