    • Facebook Graph API?– Facebooks core– Presents a simple, consistent view of the Facebook social graph– Every object in the social graph has a unique ID. You can access the properties of an object by requesting https://graph.facebook.com/ID– People and pages with usernames can be accessed using their username as an ID– All responses are JSON objects– Relationships– Reading, Searching, Publishing, Deleting, Analytics

    • Connect
    • Interactive with Facebook
    • Technical steps
    • First step• Yêu cầu chung: YOUR_APP_ID• đăng ký với FB để lấy mã ID tương tác với ứng dụng của FB (FaceBook API)• http://developers.facebook.com/setup/
    • Next step : Authentication Authenticate on your site (out of FB). Method of authentication :in code - server side : The server-side flow is used whenever you need to call the Graph API from your web serverin html - client side : The client-side flow is used when you need to make calls to the Graph API from a client, such as JavaScript running in a Web browser or from a native mobile or desktop app Iusse request :https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&scope=email,read_stream Return code to get access token key:Kết thúc Authentication thì FB sẽ trả về code để lấy token code và access vào graph protocol của FB để lấy các loại dữ liệu khácnguồn tham khảo : http://developers.facebook.com/docs/authentication
    • ReadingUsing access token key, issuing HTTP GET requests , return data in jsonví dụ truy cập feed :https://graph.facebook.com/id/feed?access_token=2227470867|2.AQA_W4-fDdlG-erj.3600.1306126800.0-1090002606|Ktp_XdsULJo0j-CAaUratCxJKqMPhp code:<?php$readfeed_url = sprintf(https://graph.facebook.com/%d/feed?access_token=%s,$fbdata[fbid], $fbdata[access_token] ) ;$feed = json_decode(file_get_contents($readfeed_url));?>
    • PublishingUsing access token key: issuing HTTP POST requestsPhp code tương ứng :<?php$token = 3523452345.....$message = "Hello, Arjun. I like this new API";$uid = arjun$url = https://graph.facebook.com/$uid/feed?access_token=$token&message=$message&method=post$result = file_get_contents($url);?>
    • Alternatively, OpenSocial
    • Market Size and Competition• Ideally speaking, OpenSocial has a market potential for 250 million users as opposed to 64 million active users on Facebook• 15,000 Applications on Facebook. Difficult to rapidly grow user base due to a saturated market• Most existing Google Widgets can run on OpenSocial. Results? Difficult to rapidly grow user base due to existing competition
    • Technical Differences• Facebook requires proprietary languages (FBML, FQL, FBJS). Google requires XML and JavaScript• Google provides an IDE (aka Google Gadget Editor)• Google hosts applications for free. Facebook doesn’t
    • Language SupportFacebook API OpenSocial API• FBML • XHTML/XML• FQL • JavaScript• FBJS • Full Support for AJAX• Partial support for AJAX • Backend languages like• Backend languages like PHP, Java, .NET on PHP, Java, .NET on Canvas Canvas
    • FB and Open social• The choice of your platform should depend on demographic• OpenSocial is modeled after Facebook. So if you’ve built a Facebook application before, it is relatively easy to learn OpenSocial• “Write Once, Run Anywhere” is not exactly true. An Orkut specific OpenSocial app. Might not necessairly run on Hi5
