In my django project i need to send a zip file to the client

  • 0

In my django project i need to send a zip file to the client side for download.This zip file would contain images downloaded from various url’s.

Is it possible to download the images in memory without writing the image files to disk then add them to a zip file in memory itself,again not writing the zip file to disk and finally sending the zip file to the client for download ?

Im aware that urllib2 can be used for image downloads and zipfile for working with zip files but facing a problem with performing these operations in memory itself.So,some example for this would be really appreciated.

Thank You

    Download the file with urllib2. Open a new ZipFile for writing (you’ll need a StringIO object for this). Write the output from the url into ZilpFile.writestr. Attach zip file to django response.

    import urllib2
from StringIO import StringIO

url = urllib2.urlopen('http://example.com/foo.jpg')
f = StringIO()
zip = zipfile.ZipFile(f, 'w')
zip.writestr('foo.jpg', url.read())
response = HttpResponse(f.getvalue(), content_type="application/zip")
response['Content-Disposition'] = 'attachment; filename=foobar.zip'
return response
