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<?xml version="1.0" encoding="UTF-8" ?><Module><ModulePrefs title="List Friends Example"><Require feature="opensocial-0.7"/></ModulePrefs> <Content type="html"> <![CDATA[ <script type="text/javascript"> function getData() { var req = opensocial.newDataRequest(); req.add(req.newFetchPersonRequest(opensocial.DataRequest.PersonId.VIEWER), 'viewer'); req.add(req.newFetchPeopleRequest(opensocial.DataRequest.Group.VIEWER_FRIENDS), 'viewerFriends'); req.send(onLoadFriends); }; function onLoadFriends(dataResponse) { var viewer = dataResponse.get('viewer').getData(); var viewerFriends = dataResponse.get('viewerFriends').getData(); var html = '<table>'; var i = 1; viewerFriends.each(function(person) { if (i == 1) { html += '<tr>'; } html += '<td><img src=\"' + person.getField(opensocial.Person.Field.THUMBNAIL_URL) + '\"/></td>'; html += '<td>' + person.getDisplayName() + '</br></td>'; if (i == 4) { i = 0; html += '</tr>'; } i++; }); document.getElementById('friends').innerHTML = html; document.getElementById('viewer').innerHTML = viewer.getDisplayName(); }; gadgets.util.registerOnLoadHandler(getData); </script> ... ]]> </Content></Module>
