APIs
write once, run
everywhere

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.

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

Facebook API

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

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.

OpenSocial API
