  18. OpenSocial 0.8 Support

  19. What is OpenSocial? • For developing applications on social networks • Accessing social data (profiles, connections) • Fetching and inserting activities Implemented by many containers • Develop once, distribute broadly •

  20. Fetching User Data & Making Requests • Examples for OpenSocial & PHP • Fetching Profiles • Fetching and Inserting Updates • Fetching Connections • Making YQL Requests

  21. Collecting User Data With PHP & OpenSocial 0.8 $session = YahooSession::requireSession($key, $secret, $app_id) $user = $session->getSessionedUser(); $profile = $user->getProfile(); --------------------------------------------------------------------------------------------------------------- var req = opensocial.newDataRequest(); var params = {}; params[opensocial.DataRequest.PeopleRequestFields.PROFILE_DETAILS] = [ opensocial.Person.Field.NAME, opensocial.Person.Field.THUMBNAIL_URL ]; req.add(req.newFetchPersonRequest('VIEWER', params), 'viewer_profile'); req.send(response);

  22. Fetching Updates With PHP & OpenSocial 0.8

  23. Getting Updates With PHP & OpenSocial 0.8 $session = YahooSession::requireSession($key, $secret, $app_id) $user = $session->getSessionedUser(); $updates = $user->getUpdates(); ------------------------------------------------------------------------------- var req = opensocial.newDataRequest(); var spec = new opensocial.IdSpec(); spec.setField(opensocial.IdSpec.Field.USER_ID, opensocial.IdSpec.PersonId.OWNER); req.add(req.newFetchActivitiesRequest(spec), 'ownerActivities'); req.send(handleActivities);

  24. Inserting Updates With PHP & OpenSocial 0.8 $session = YahooSession::requireSession($key, $secret, $app_id) $user = $session->getSessionedUser(); $update = $user->insertUpdate($suid, $title, $link, $description); -------------------------------------------------------------------------- var params = {}, activity; params[opensocial.Activity.Field.TITLE] = title; params[opensocial.Activity.Field.BODY] = body; activity = opensocial.newActivity(params); opensocial.requestCreateActivity( activity, opensocial.CreateActivityPriority.LOW, callback);

  25. Fetching Connections With PHP & OpenSocial 0.8

  26. Fetching Connections With PHP & OpenSocial 0.8 $session = YahooSession::requireSession($key, $secret, $app_id) $user = $session->getSessionedUser(); $connections = $user->getConnections(); ------------------------------------------------------------------------- var req = opensocial.newDataRequest(); var idspec = opensocial.newIdSpec({ 'userId' : 'OWNER', 'groupId' : 'FRIENDS' }); req.add(req.newFetchPersonRequest('OWNER'), 'get_owner'); req.add(req.newFetchPeopleRequest(idspec), 'get_friends'); req.send(responseFriends);

  27. Making YQL Requests With PHP & OpenSocial 0.8 $session = YahooSession::requireSession($key, $secret, $app_id) $query = $session->query(‘select * from maps.map where zip="94085" ’); ------------------------------------------------------------------------- var params = {}; var url = 'http://developer.yahoo.com/yql/console/?q=select%20*%20from %20flickr.photos.search%20where%20text%3D%22Times%20Square%22' var callback = callbackFunc; params[gadgets.io.RequestParameters.CONTENT_TYPE] = gadgets.io.ContentType.TEXT; params[gadgets.io.RequestParameters.METHOD] = gadgets.io.MethodType.GET; gadgets.io.makeRequest(url, callback, params);

Important URLs OpenSocial Site Links http://wiki.opensocial.org/index.php?title=Opensocial_(v0.8) http://wiki.opensocial.org/index.php?title=Opensocial.Person_%28v0.8%29 Developer Network Links http://developer.yahoo.com/yap/guide/os-supp-features.html http://developer.yahoo.com/yap/guide/opensocial-examples.html

  29. The Yahoo! Social APIs

  30. What are the Social APIs? Social Directory API Reference http://developer.yahoo.com/social/rest_api_guide/social_dir_api.html Status API Reference http://developer.yahoo.com/social/rest_api_guide/status_api.html Contacts API Reference http://developer.yahoo.com/social/rest_api_guide/contact_api.html Updates API Reference http://developer.yahoo.com/social/rest_api_guide/updates_api.html

  31. Calling the Social APIs with the SDK Functions Given: $ysession = YahooSession::requireSession(API_KEY, API_SECRET, APP_ID); $yuser = $ysession->getSessionedUser(); Social Directory API (Profile & Connections) $yuser->loadProfile(); $yuser->getConnections($start, $count, $total); Status API $yuser->getStatus();

  32. Calling the Social APIs with the SDK Functions Given: $ysession = YahooSession::requireSession(API_KEY, API_SECRET, APP_ID); $yuser = $ysession->getSessionedUser(); Contacts API $yuser->getContacts($start, $count); Updates API $yuser->getUpdates($start, $count);

  33. Front-End Security JavaScript / HTML / CSS

  34. Front-end Security

  35. Front-end Security: Caja Caja Security • Very secure model (whitelist methodology) • Aims to protect end-users • Full content control IFrame Concerns • Drive-by downloads • No content restrictions • Other known exploits

  36. Front-end Security: Caja Cajoling Process <script type="text/javascript"> function response(obj) { if (obj.text){ document.getElementById('interact').setInnerHTML('Populated!'); document.getElementById('population').setInnerHTML(obj.errors); } } </script>

  37. Front-end Security: Caja Cajoling Process var $dis = $v.getOuters(); $v.initOuter('onerror'); $v.so('response', ___.markFuncFreeze(function () { function response$_caller($dis, obj) { if ($v.r(obj, 'text')) { $v.cm($v.cm($v.ro('document'), 'getElementById', [ 'interact' ]), 'setInnerHTML', [ 'Populated!' ]); $v.cm($v.cm($v.ro('document'), 'getElementById', [ 'population' ]), 'setInnerHTML', [ $v.r(obj, 'errors') ]); } } response$_caller.FUNC___ = 'response$_caller'; var response;; response = $v.dis(___.primFreeze(response$_caller), 'response'); return response;

  38. What isn’t supported in YAP? Blacklisted HTML tags http://developer.yahoo.com/yap/guide/caja-blacklist.html Caja Limitations http://developer.yahoo.com/yap/guide/what-are-cajas-limitations.html

  39. What isn’t supported in YAP? • AJAX functionality (use YML / OpenSocial) Most JavaScript libraries • Script Source Includes (except YUI) •

  40. BETA YUI Support

  41. How to Implement YUI Implementing as includes <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0/build/ya hoo-dom-event/yahoo-dom- event.js"></script> Insert content into a script block
