Saving animated GIFs using urllib.urlopen (image saved does not animate)
- by wenbert
I have Apache2 + Django + X-sendfile. My problem is that when I upload an animated GIF, it won't "animate" when I output through the browser.
Here is my code to display the image located outside the public accessible directory.
def raw(request,uuid):
target = str(uuid).split('.')[:-1][0]
image = Uploads.objects.get(uuid=target)
path = image.path
filepath = os.path.join(path,"%s.%s" % (image.uuid,image.ext))
response = HttpResponse(mimetype=mimetypes.guess_type(filepath))
response['Content-Disposition']='filename="%s"'\
%smart_str(image.filename)
response["X-Sendfile"] = filepath
response['Content-length'] = os.stat(filepath).st_size
return response
UPDATE
It turns out that it works. My problem is when I try to upload an image via URL. It probably doesn't save the entire GIF?
def handle_url_file(request):
"""
Open a file from a URL.
Split the file to get the filename and extension.
Generate a random uuid using rand1()
Then save the file.
Return the UUID when successful.
"""
try:
file = urllib.urlopen(request.POST['url'])
randname = rand1(settings.RANDOM_ID_LENGTH)
newfilename = request.POST['url'].split('/')[-1]
ext = str(newfilename.split('.')[-1]).lower()
im = cStringIO.StringIO(file.read()) # constructs a StringIO holding the image
img = Image.open(im)
filehash = checkhash(im)
image = Uploads.objects.get(filehash=filehash)
uuid = image.uuid
return "%s" % (uuid)
except Uploads.DoesNotExist:
img.save(os.path.join(settings.UPLOAD_DIRECTORY,(("%s.%s")%(randname,ext))))
del img
filesize = os.stat(os.path.join(settings.UPLOAD_DIRECTORY,(("%s.%s")%(randname,ext)))).st_size
upload = Uploads(
ip = request.META['REMOTE_ADDR'],
filename = newfilename,
uuid = randname,
ext = ext,
path = settings.UPLOAD_DIRECTORY,
views = 1,
bandwidth = filesize,
source = request.POST['url'],
size = filesize,
filehash = filehash,
)
upload.save()
#return uuid
return "%s" % (upload.uuid)
except IOError, e:
raise e
Any ideas?
Thanks!
