My work on getting sm-photo-tool to use smugmug’s REST API continues. It’s been slow going as I’m also learning python as I go.

Tonight I can get image and album info using the REST API which returns me an XML document. I parse the document using DOM, and dynamically create a class with an internal map (or dict in python) of attributes.

Here’s a sample response from the getImageInfo REST API call:

<?xml version="1.0" encoding="utf-8" ?>
<rsp stat="ok">
 <method>smugmug.images.getInfo</method>
  <Info>
   <Image id="134646762">
    <Album id="2559293" />
    <FileName>IMG_0112.JPG</FileName>
    <Caption />
    <Keywords />
    <Position>1</Position>
    <Date>2007-03-08 17:48:25</Date>
    <Format>JPG</Format>
    <Serial>0</Serial>
    <Watermark>0</Watermark>
    <Size>2553371</Size>
    <Width>2592</Width>
    <Height>1944</Height>

    <AlbumURL>http://familiarodriguez.smugmug.com/gallery/2559293/1/134646762</AlbumURL>
   </Image>
  </Info>
</rsp>

This is the class I want to create:

class Image:
    def __init__(self):
        self.data = {}
    def __setitem__(self, key, value):
        #print "__setitem__(%s:%s)" % (key,value)
        self.data[key.lower()] = value
    def __getitem__(self, key):
        #print “__getitem__(%s)” % (key)
        return self.data[key.lower()]
    def __str__(self):
        return str(self.data)

This makes it easy to use the resulting object.

    print "getimageinfo ---------------------------------------"
    imgInfo = sm1.getImageInfo(sessionid, images[0])
    print “imageinfo: ” + str(imgInfo)
    print “TinyURL = ” + imgInfo['TinyURL']
    print “imageid = ” + imgInfo['imageid']
    print “albumId = ” + imgInfo['albumId']

All of the code can be found here..

A more OO way is to have getter and setter methods, but I really like the ability to treat an object as a map and send it “messages”. I despise getters and setters now.

Off to bed now.
