Collecting User Data With OpenSocial 0.8
/* OpenSocial PERSON data request */
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);

Collecting User Data With OpenSocial 0.8
/* response handler */
function response(data){
var viewer = data.get('viewer_profile').getData();
var aboutme =
viewer.getField(opensocial.Person.Field.NAME);
}

PHP Example: OAuth Dance
$session = YahooSession::requireSession($key, $secret, $app_id)
$user = $session->getSessionedUser();
var_dump($user);

PHP Example: Fetching Profile Data
$profile = $user->getProfile();
var_dump($profile);

Python Example: OAuth Dance
oauthapp = yahoo.application.OAuthApplication(key, secret, app_id, callback)
# fetch unauthorized request token
request_token = oauthapp.get_request_token(callback)
# authorize request token
authorization_url = oauthapp.get_authorization_url(request_token)
# refresh authorized request token with access token
access_token = oauthapp.get_access_token(request_token)
oauthapp.token = access_token

Python Example: Fetching Profile Data
profile = oauthapp.getProfile()
print profile

Yahoo! Updates

Getting Updates With OpenSocial 0.8
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);

Getting Updates With OpenSocial 0.8
function handleActivities(dataResponse) {
var ownerActivities = dataResponse.get('ownerActivities').getData();
//parse owner activities
}

PHP Example: Fetching Updates
$updates = $user->getUpdates();
var_dump($updates);

Python Example: Fetching Updates
updates = oauthapp.getUpdates()
print updates

Inserting Updates with OpenSocial 0.8
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);

PHP Example: Inserting Updates
$update = $user->insertUpdate($suid, $title, $link, $description);
var_dump($update);

Python Example: Inserting Updates
update = oauthapp.insertUpdate(title, description, link)
print update

Fetching Connections With OpenSocial 0.8
/* get owner and owner friends */
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);

Fetching Connections With OpenSocial 0.8
/* connection response function */
function responseFriends(data){
var owner = data.get('get_owner').getData();
var objFriends = data.get('get_friends').getData();
var html = 'Friends of ' +
owner.getDisplayName() + '<br />';
objFriends.each(function(person) {
html += person.getDisplayName() + '<br />';
});
}

PHP Example: Fetching Connections
$connections = $user->getConnections();
var_dump($connections);

Python Example: Fetching Connections
connections = oauthapp.getConnections()
print connections

The Yahoo! Query Language (YQL)
SELECT myColumn, myTitle
FROM myTable
WHERE col = 'value' AND var = 'title‘
LIMIT 3 OFFSET 10 |
sort(field='myColumn') | reverse()

Getting Social Data with YQL
select * from social.profile where guid=me
select * from social.connections where owner_guid=me
select message from social.profile.status where guid=me
select * from social.updates where guid=me

Making AJAX Requests With OpenSocial 0.8
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);

Making AJAX Requests With OpenSocial 0.8
function callbackFunc(response){
if (response.text){
//use response.txt
}
}

PHP Example: Executing YQL
$application = new YahooApplication($key, $secret);
$results = $application->query(‘select * from delicious.feeds.popular’);
var_dump($results);

Python Example: Executing YQL
results = oauthapp.yql('select * from social.profile where guid=me')
print results
