45. Facebook API
API: REST & JavaScript brinda acceso a datos del usuario
y sus amigos.
(FQL, “Facebook Query Language”): lenguaje que
permite consultas complejas para obtener datos del
usuario y sus amigos.
(FBML, “Faceboook Markup Language”): lenguaje markup
similar al HTML.

46. Facebook API
<?php require_once 'appinclude.php';?>
<h1>
Mi primer canvas!</p>
Hola <fb:name uid=quot;<?=$user;?>quot; useyou=quot;falsequot;/></p>
Tus amigos son:</p>
<table>
<?php
$i = 1;
foreach ($facebook->api_client->friends_get() as $friend_id) {
if ($i == 1){
echo quot;<tr>quot;;
}
echo quot;<td>quot; . quot;<fb:profile-pic uid='quot; . $friend_id . quot;'/>quot; . quot;</td>quot;;
echo quot;<td>quot; . quot;<fb:name uid='quot; . $friend_id . quot;'/></br>quot; . quot;</td>quot;;
if ($i == 4) {
$i = 0;
echo quot;</tr>quot;;
}
$i++;
}
?>
</table>
</h1>

47. Facebook API

48. OpenSocial API
2 roles:
• container: implementa la API
• application: usa la API
2 modos:
• Javascript API
• RESTfull API (en desarrollo)

49. OpenSocial API
Datos accesibles:
• people: información sobre personas y amigos.
• activities: permite publicar y recibir actividades de las
personas.
• persistence: utilizando una abstracción del tipo (clave, valor)
permite a las aplicaciones persistir su propia información.
