Python CGI to Display Flickr Images

From: "andrew cooke" <andrew@...>

Date: Sun, 15 Jun 2008 03:27:10 -0400 (CLT)

I am rewriting my website (not yet public) and wanted to include the
latest images from my flickr page.  At first I assumed this would be AJAX,
but it turns out to be simpler to just use an iframe (saves you rewriting
the DOM yourself).

The following code, run as a cgi, pulls details of the last 4 images from
my flickr account and generates the HTML for the iframe.  To re-use you
need to add your own api_key (and change parameters to get the user you
want).

I didn't use XSL because that's not in the standard Python libs and this
has to run on my ISP.

 #!/usr/bin/python2.5

 from httplib import HTTPConnection
 from re import compile

 photos = compile(r'(<photo [^>]+>)(.*)')
 attributes = compile(r'([a-z]+)="([^"]+)"(.*)')

 cnx = HTTPConnection("api.flickr.com")
 cnx.request("GET",
 "/services/rest/?method=flickr.people.getPublicPhotos&api_key=...&user_id=...&per_page=4")
 rsp = cnx.getresponse()
 if 200 == rsp.status:
     print "Content-type: text/html"
     print
     print """<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

     <title>

     </title>
   </head>
   <body>"""
     xml = rsp.read()
     xml = xml.replace('\r', ' ')
     xml = xml.replace('\n', ' ')
     while xml:
         match = photos.search(xml)
         if match:
             (photo, xml) = photos.search(xml).groups()
             attrs = {}
             while photo:
                 match = attributes.search(photo)
                 if match:
                     photo = match.group(3)
                     attrs[match.group(1)] = match.group(2)
                 else:
                     photo = ''
             print '<a
 href="http://www.flickr.com/photos/acooke/%(id)s"><img
 src="http://farm%(farm)s.static.flickr.com/%(server)s/%(id)s_%(secret)s_s.jpg"/></a>'
 % attrs
         else:
             xml = ''
     print """  </body>
 </html>"""
