print header(-type => ‘text/xml’);

my @query;

foreach my $param (param())

{

push @query,sprintf(‘%s=%s’,$param,param($param));

}

my $query = ‘http://www.flickr.com/services/rest/?’. join(‘&’,@query);

my $response = $ua->get($query);

print $response->{_content};

Now you can build a URL just as if you were directly building one for the Flickr service and

access the information returned by Flickr without hitting the browser security issue that pre-

vents you from doing this directly.

Searching Flickr for Photos

You can search for Flickr photos using a variety of criteria with the flickr.photos.search

method. You can request photos based on the following search criteria:

User ID


Tags (you can also specify whether to search for photos matching any tags or to search

for all of them)

Text search (based on title, description, or tag)


Upload date

Taken date


License

You can also specify the sort order of the returned list of photos, the number of photos to be

returned in a page (up to 500), and which page of the search requested to return photos. For

example, if you request 100 photos per page from page 3, photos start at number 301 in the

returned results.

Sending a Search Request

You can submit a search for a specific user’s photos (I’ll use my photos as an example) and look

for photos with specific tags. When you send the request with the REST interface, XML for the

photo information is returned. You can see a sample of the returned data in the following code:

<rsp stat=”ok”>

<photos page=”1” pages=”1” perpage=”100” total=”79”>

<photo id=”24910903” owner=”54256647@N00” secret=”ad24b49370” server=”23” ;

title=”IMG_0776” ispublic=”1” isfriend=”0” isfamily=”0”/>

<photo id=”24910888” owner=”54256647@N00” secret=”1b92a07883” server=”23” ;

title=”IMG_0777” ispublic=”1” isfriend=”0” isfamily=”0”/>
