Django: serving an image from a remote server
For a current project (using django), I wanted to get a dynamically generated image from a remote map server and return the image to the django view as an object (as opposed to returning a URL as a string).
Here's how it's done (logic derived from this code snippet):
import urllib import urllib2 import mimetypes def serveMapImage( theArea ): # omitted: procedure to define the variable zoomExtents # from user-specified, database-derived variable theArea URI = "http://example.com/mapofsouthafrica-" + zoomExtents contents = urllib2.urlopen(URI).read() mimetype = mimetypes.guess_type(URI) response = HttpResponse(contents, mimetype=mimetype) return response
