NAME

WWW::BF2S - Get Battlefield 2 Player Stats

SYNOPSIS

use WWW::BF2S;
my $bf2 = Net::BF2S->new;
my $data = $bf2->getStats(45355493,64573414,64318788,64246757,62797217,61091442,64964638,64661842,65431962,58968459);

DESCRIPTION

Fetches Battlefield 2 player stats from BF2S.

You must use the PID (player ID) when requesting stats. If you try to request the player stats by player name, the module will ignore it and move on to the next one in the list. You can get the PID from many sources, including the BF2S.com website.

You can only make THREE requests for data in a SIX hour period. This is a restriction from the feed provider, not the module. Try to ask for as many PIDs as possible in one request. The module is being written (this part is coming soon) in a way that will try to include a list of "PID Request Candidates" (a list of PIDs that you've asked for before, but you didn't ask for this time around) that will also be requested in that same request, which is meant to update your local player Stat Cache when possible.

I'll provide more documentation later.

getStats

Access this method in an OO way.

my $data = $bf2->getStats(65431962,64246757,64661842);

It will return a hashref that contains data for the PIDs requested. It is in this format:

$data = {
           '65431962' => {
                          'country' => 'US',
                          'link' => 'http://bf2s.com/player/65431962/',
                          'time' => '525400',
                          'deaths' => '5332',
                          'nick' => 'Rd54321',
                          'score' => '9757',
                          'wins' => '222',
                          'losses' => '368',
                          'pid' => '65431962',
                          'updated' => 1148275361,
                          'rank' => '6',
                          'kills' => '3237'
                        },
          '64246757' => {
                          'country' => 'US',
                          'link' => 'http://bf2s.com/player/64246757/',
                          'time' => '272092',
                          'deaths' => '1739',
                          'nick' => 'dustyheynu',
                          'score' => '5076',
                          'wins' => '76',
                          'losses' => '110',
                          'pid' => '64246757',
                          'updated' => 1148275361,
                          'rank' => '5',
                          'kills' => '1130'
                        },
          '64661842' => {
                          'country' => 'US',
                          'link' => 'http://bf2s.com/player/64661842/',
                          'time' => '1008165',
                          'deaths' => '11902',
                          'nick' => 'READYORNOTHEREICOME',
                          'score' => '29062',
                          'wins' => '550',
                          'losses' => '689',
                          'pid' => '64661842',
                          'updated' => 1148275361,
                          'rank' => '8',
                          'kills' => '8757'
                        }
        };

It will only fetch data that is at least two hours old. Otherwise, it will serve the data from the stat cache file.

If none of the PIDs need updated (already updated within two hours), it won't send a request at all and only serve from the cache.

If at least one of the PIDs need updated (because it's older than two hours or has never been requested), it will request those PIDs that need updated. When the "PID Request Candidates" feature is ready, it will also request, at that same time, a list of "candidates" from your stat cache.

BF2S Data Source Restrictions

Because the BF2S data source limits a single IP address to only three requests in a six hours, each request needs to be used properly. Basically, you can only make a request once every two hours. The PID Request Candidates feature is here to help, or at least try.

For each request, data for a maximum of 64 PIDs will be returned.

Stats Cache

The Stats Cache (stored locally automatically) collects, combines, and stores results from every request made to the BF2S data source. If used properly, you can use this module to make requests as often as you wish (used directly on a website, for example), and unless the data in the cache has reached a certain age, every request can be served via the Stats Cache. This means that you can let this module handle the caching and you can use it as if you were asking a live source each time.

PID Request Candidates

(This is a feature that is not yet included. It is top priority and should be added to the next update.)

To make the most of the Stats Cache, every time the module deems it necessary to make a request out to the BF2S data source, it also includes, in addition to the requested PIDs, a list of other PIDs found in the Stats Cache that could be updated.

If less than the maximum number of PIDs are being requested by your application, it will include as many PIDs from your Stats Cache as possible (max 64 total). It will add those in order of needing-updated-ness. If your number of requested PIDs and the total size of your Stats Cache is smaller than the 64 max, it will just refresh your entire Stats Cache as well as include any new PIDs that weren't already in your cache.

The getStats method will still only return the PIDs you requested. This feature will simply update your cached PIDs at the same time.
