35. S OCIAL P LUGINS

36. S OCIAL P LUGINS The easiest way to get started with Facebook Platform. We Can Use iframe or XFBML method Sample Code (iframe) <iframe src=&quot;http://www.facebook.com/widgets/like.php?href= http://example.com &quot; scrolling=&quot;no&quot; frameborder=&quot;0&quot; style=&quot;border:none; width:450px; height:80px&quot;></iframe>

38. SINGLE SIGN-ON Facebook

39. Single Sign-on Oauth 2.0 protocol http://tools.ietf.org/html/draft-ietf-oauth-v2-08 http://hueniverse.com/2010/05/introducing-oauth-2-0/ We Can get basically: All general information: like name, profile picture, gender and network. We can get more Ask extended Permisson http://developers.facebook.com/docs/authentication/permissions JavaScript SDK is a simple way <div id=&quot;fb-root&quot;></div> <script src=&quot;http://connect.facebook.net/en_US/all.js&quot;></script> <script> FB.init({appId: ' your app id ', status: true, cookie: true, xfbml: true}); FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { // A user has logged in, and a new cookie has been saved } else { // The user has logged out, and the cookie has been cleared } }); </script>

40. Single Sign-on How to and Flow Register Our App http://tools.ietf.org/html/draft-ietf-oauth-v2-08 http://hueniverse.com/2010/05/introducing-oauth-2-0/ Redirect the user to https://graph.facebook.com/oauth/authorize with client_id After the user authorizes your application, Facebook redirects the user to the callback URL you specified with the access token in the URL fragment: Use the access token returned by the request above to fetch data from the Graph API on behalf of the user.

41. Extended Permission Register Our App http://tools.ietf.org/html/draft-ietf-oauth-v2-08 http://hueniverse.com/2010/05/introducing-oauth-2-0/ http://developers.facebook.com/docs/authentication/permissions

42. GRAPH API Facebook

43. Register Apps http://www.facebook.com/?ref=logo#!/developers/apps.php

44. Graph API (1) - get data https://graph.facebook.com/ID

45. Graph API (2) - get data https://graph.facebook.com/ID/CONNECTION_TYPE

46. Graph API (3) - selection, Introspection https://graph.facebook.com/ID?fields=A,B,C... https://graph.facebook.com/?ids=XXX,YYY

47. Graph API (4) POST We can publish to the Facebook graph by issuing HTTP POST requests to the appropriate connection URLs

48. Graph API (5) Delete We can delete objects in the graph by issuing HTTP DELETE requests to the object DELETE https://graph.facebook.com/ID?access_token=... HTTP/1.1 OR https://graph.facebook.com/COMMENT_ID?method=delete

49. Graph API (6) Search We can search over all public objects https://graph.facebook.com/search?q=QUERY&type=OBJECT_TYPE For Example All public posts: https://graph.facebook.com/search?q=watermelon&type=post People: https://graph.facebook.com/search?q=mark&type=user Pages: https://graph.facebook.com/search?q=platform&type=page Events: https://graph.facebook.com/search?q=conference&type=event Groups: https://graph.facebook.com/search?q=programming&type=group

61. JAVASCRIPT SDK Facebook

62. JavaScript SDK(1) The JavaScript SDK enables you to access all of the features of the Graph API via JavaScript The JavaScript SDK is also necessary to use the XFBML Must register your application. The SDK is open source and is available on http://github.com/facebook/connect-js

63. JavaScript SDK(2) Core Methods Event Handling XFBML Methods Data Access Utilities Canvas Methods

64. JavaScript SDK(3) – Core Methods FB.api Make a API call <script> FB.api('/me', function(response) { console.log(response); }); </script>

65. JavaScript SDK(4) – Core Methods FB.getLoginStatus Find out the current status from the server, and get a session if the user is connected. <script> FB.getLoginStatus(function(response) { if (response.session) { alert('Coneected'); } else { alert('No Coneected'); } }); </script>

66. JavaScript SDK(5) – Core Methods FB.login Login/Authorize/Permissions. <button id=&quot;fb-login&quot;>Login</button> <script> document.getElementById('fb-login').onclick = function() { FB.login(function(response) { Log.info('FB.login callback', response); if (response.session) { Log.info('User is logged in'); } else { Log.info('User is logged out'); } }); }; </script>

67. JavaScript SDK(6) – Core Methods FB.logout Logout the user in the background. <button id=&quot;fb-logout&quot;>Logout</button> <script> document.getElementById('fb-logout').onclick = function() { FB.logout(function(response) { alert('logout!'); // user is now logged out }); }; </script>

68. JavaScript SDK(7) – Core Methods FB.ui Method for triggering UI interaction with Facebook as IFrame dialogs or popups, like publishing to the stream, sharing links. <script> var share = { method: 'stream.share', u: 'http://www.cht.com.tw/' }; FB.ui(share, function(response) { console.log(response); }); </script>

69. JavaScript SDK(8) – Event Handling FB.Event.subscribe Subscribe to a given event name, invoking your callback function whenever the event is fired. <script> FB.Event.subscribe('auth.sessionChange', function(response) { // do something with response.session }); </script>

70. JavaScript SDK(9) – Event Handling FB.Event.unsubscribe Removing a subscriber is basically the same as adding one <script> var onSessionChange = function(response) { // do something with response.session }; FB.Event.subscribe('auth.sessionChange', onSessionChange); FB.Event.unsubscribe('auth.sessionChange', onSessionChange); </script>

71. JavaScript SDK(10) – Data Access FB.Data.query Removing a subscriber is basically the same as adding one FB.Data.waitOn Wait until the results of all queries are ready <script> var onSessionChange = function(response) { // do something with response.session }; FB.Event.subscribe('auth.sessionChange', onSessionChange); FB.Event.unsubscribe('auth.sessionChange', onSessionChange); </script>

72. JavaScript SDK(11) - Canvas Methods FB.Canvas.setAutoResize Starts or stops a timer which resizes your iframe every few milliseconds. FB.Canvas.setSize Tells Facebook to resize your iframe.

79. Register facebook application - 基本資料

80. Register facebook application – 驗證 參數 說明 Installable to? 什麼可以使用應用程式，共有兩種選擇，分別是個人檔案和粉絲專頁。 Post-Authorize Callback URL 當使用者第一次新增應用程式後，呼叫的網址。 Post-Remove Callback URL 當使用者移除應用程式後，呼叫的網址。

81. Register facebook application – 個人檔案 參數 說明 標籤名稱 顯示在個人檔案頁籤的名稱。 標籤網址 當點選頁籤時所載入的網址。 Post-Remove Callback URL 當使用者移除應用程式後，呼叫的網址。

90. FACEBOOK QUERY LANGUAGE Facebook

91. FQL(1) Facebook Query Language Enables we to use a SQL-style interface to query the data https://api.facebook.com/method/fql.query?query=QUERY. Table

92. FQL(2) – Testing Tool http://developers.facebook.com/docs/reference/rest/fql.query

93. FQL(3) – 支援基本的運算字 參數 說明 + 加法 - 減法 * 乘法 / 除法 > 大於 < 小於 >= 大於等於 <= 小於等於 = 等於 AND 及 OR 或 NOT 不是

94. FQL(4) – 支援的函式 參數 說明 now() 取得現在的時間。 rand() 產生亂數。 strlen(string) 計算字串長度。 concat(string, ...) 合併本函式中的所有字串。 substr(string, start, length) 根據字串開始位置 start 和取得長度 length 兩個參數，取得 string 字串的部份文字。 strpos(haystack, needle) 搜尋 haystack 字串，找出該字串中第一次出現 needle 字串的位置，若找不到符合 needle 字串的文字，則回傳 -1 。 lower(string) 將字串轉換成小寫。 upper(string) 將字串轉換成大寫。

95. FQL(5) – Table : link_stat Query this table to return detailed information from your Facebook Share implementation SELECT share_count, like_count, comment_count, total_count,click_count FROM link_stat WHERE url=&quot;http://www.yahoo.com&quot;

96. FQL(6) – Table : friend Query this table to determine whether two users are linked together as friends. 確認 uid1 跟 uid2 是否為朋友，若雙方不是朋友，將會取得空字串。 select uid1,uid2 from friend where uid1=4 and uid2=5 取得 uid1 的朋友清單 select uid1,uid2 from friend where uid1= 登入者的 UID

97. FQL(7) – Tables stream SELECT actor_id, message FROM stream WHERE source_id = <user id> limit 5 photo_tag SELECT pid FROM photo_tag WHERE subject=$uid photo SELECT src_big FROM photo WHERE pid IN ( SELECT pid FROM photo_tag WHERE subject=$uid )

98. FBML Facebook

99. FBML(1) FBML enables you to build Facebook applications that deeply integrate into a user's Facebook experience.

100. FBML(2) Tools User/Groups Notifications and Requests Platform Internationalization Status Messages Page Navigation Wall Visibility on Profile Profile-specific Misc Editor Display Embedded Media Dialog Additional Permissions Social Widgets Message Attachments Forms

101. FBML(3) <fb: 語法名稱 參數一 =&quot; 參數值 &quot; 參數二 =&quot; 參數值 &quot; ‧‧‧ > 傳入內容 </fb: 語法名稱 >

102. FBML(4)

103. FBML(5) http://developers.facebook.com/docs/reference/fbml/ http://developers.facebook.com/tools/console/

104. FBML(6) <fb:bookmark></fb:bookmark> <fb:comments xid=&quot;titans_comments&quot; canpost=&quot;true&quot; candelete=&quot;false&quot; returnurl=&quot;http://apps.facebook.com/myapp/titans/&quot;></fb:comments>

105. OLD REST API The old REST API is the previous version of the Graph API. If we are new to the Facebook Platform, Facebook recommend you use our new Graph API instead.
