How do I modify this download function in Python?
- by TIMEX
Right now, it's iffy. Gzip, images, sometimes it doesn't work.
How do I modify this download function so that it can work with anything? (Regardless of gzip or any header?)
How do I automatically "Detect" if it's gzip? I don't want to always pass True/False, like I do right now.
def download(source_url, g = False, correct_url = True):
try:
socket.setdefaulttimeout(10)
agents = ['Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)','Mozilla/4.0 (compatible; MSIE 7.0b; Windows NT 5.1)','Microsoft Internet Explorer/4.0b1 (Windows 95)','Opera/8.00 (Windows NT 5.1; U; en)']
ree = urllib2.Request(source_url)
ree.add_header('User-Agent',random.choice(agents))
ree.add_header('Accept-encoding', 'gzip')
opener = urllib2.build_opener()
h = opener.open(ree).read()
if g:
compressedstream = StringIO(h)
gzipper = gzip.GzipFile(fileobj=compressedstream)
data = gzipper.read()
return data
else:
return h
except Exception, e:
return ""
