Open Graph Getting Started App – og.likes



// This is boilerplate code that is used to initialize the Facebook // JS SDK. You would normally set your App ID in this code.

// Additional JS functions here window.fbAsyncInit = function() { FB.init({ appId : fbAppId, // App ID status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse page for xfbml or html5 social plugins like login button below });

// Put additional init code here };

// Load the SDK Asynchronously (function(d, s, id){ var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) {return;} js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));

/* * This function makes a call to the og.likes API. The object argument is * the object you like. Other types of APIs may take other arguments. * (i.e. the book.reads API takes a book= argument.) * * Because it's a sample, it also sets the privacy parameter so that it will * create a story that only you can see. Remove the privacy parameter and * the story will be visible to whatever the default privacy was when you * added the app. * * Also note that you can view any story with the id, as demonstrated with * the code below. * * APIs used in postLike(): * Call the Graph API from JS: * https://developers.facebook.com/docs/reference/javascript/FB.api * The Open Graph og.likes API: * https://developers.facebook.com/docs/reference/opengraph/action-type/og.likes * Privacy argument: * https://developers.facebook.com/docs/reference/api/privacy-parameter */

function postLike() { FB.api( 'https://graph.facebook.com/me/og.likes', 'post', { object: objectToLike, privacy: {'value': 'SELF'} }, function(response) { if (!response) { alert('Error occurred.'); } else if (response.error) { document.getElementById('result').innerHTML = 'Error: ' + response.error.message; } else { document.getElementById('result').innerHTML = '' + 'Story created. ID is ' + response.id + ''; } } ); }

This example creates a story on Facebook using the og.likes API. That story will just say that you like an article on TechCrunch. The story should only be visible to you.
