Proxy Script To Yahoo API Term Extraction

Paul Kinlan

Finally, here it is after a busy week.

What follows is a listing of the code I created to create a proxy that would allow me to access the Yahoo API from any browser with out having to worry about Cross Site Scripting.

This works in Internet Explorer (IE6, IE7) and firefox, and is used in my AJAX example.

Bascially, it retrieves a POST request from the browser and forwards the result inside another POST request to Yahoo, once I recieve the response, I pass back the XML to the web browser.

And thats it really.

Do you have any Questions, email me: Paul Kinlan [paul.kinlan@gmail.com]

#!/usr/bin/perl
use LWP;
use CGI qw(:standard);
$CGI::POST_MAX=1024 * 100; # max 100K posts
my($qCGI) = new CGI();
my($YahooAppID) = “APPIDHERE”;

my($baseUrl) = “http://api.search.yahoo.com/
ContentAnalysisService/V1/termExtraction”;

my($context)= $qCGI->param(‘context’);
my($query) = $qCGI->param(‘query’);
my($finalUrl) = $baseUrl ;

$ua = LWP::UserAgent->new;
$ua->agent(“YahooPassThrough/0.1 “);

# Create a request
my $req = HTTP::Request->new(POST => $finalUrl);
$req->content(“appid=”.$YahooAppID.”&context=“.$context.”&query”.$query);
$req->content_type(‘application/x-www-form-urlencoded’);

# Pass request to the user agent and get a response back
my $res = $ua->request($req);
print “Content-type: text/xml\n\n”;
print $res->content;
