friends on Facebook through their profile pages &

newsfeeds

even link friends that have existing accounts.

Feeds on Facebook.

• Reliability: The full power and flexibility of Facebook

Platform.

Should Use Facebook Connect?

• One-click Login: Allow users to log in with their Facebook identity and

allow your site to access their Facebook profile information.

• Increased engagement: Leverage users' personal interests to show more

relevant information and surface personalized content from friends such

as reviews or comments.

your site with friends back on Facebook through feed, invites, and other

social communication channels on Facebook.

Facebook core

Facebook Graph API?

– Facebook's 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

Object

https://graph.facebook.com/platform

Relationships

https://graph.facebook.com/ID/CONNECTION_TYPE

Technical stepsTechnical 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 server

in 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 khác

nguồn tham khảo : http://developers.facebook.com/docs/authentication

Reading

Using access token key, issuing HTTP GET requests , return data in json

ví dụ truy cập feed :

https://graph.facebook.com/id/feed?access_token=2227470867|2.AQA_W4-fDdlG-erj.3600.1306126800.0-1090002606|Ktp_XdsULJo0j-CAaUratCxJKqM

Php 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));

?>

Publishing

Using access token key: issuing HTTP POST requests

Php 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 Support

Facebook API• FBML• FQL

• FBJS

• Partial support for AJAX• Backend languages like

PHP, Java, .NET on Canvas

OpenSocial API• XHTML/XML• JavaScript

• Full Support for AJAX

• Backend languages like PHP, Java, .NET on 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
