User Interface
Visualforce PageにjQuery Mobileをロード<apex:page sidebar="false" showHeader="false" standardStylesheets="false" standardController="Session__c" extensions="sugoiSurvey" contentType="text/html" doctype="HTML-5.0"><apex:stylesheet value="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" /><apex:includescript value="http://code.jquery.com/jquery-1.7.1.min.js" /><apex:includescript value="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js" /><head>
<title>{!$label.sugoiSurvey}</title><meta name="viewport" content="width=device-width, initial-scale=1" /><script type="text/javascript">j$ = jQuery.noConflict();</script>
• <apex:stylesheet>,<apex:includescript>でライブラリ(jQuery, jQuery Mobile)をロード• <meta name="viewport">で表示サイズをモバイル端末画面に最適化• jQuery.noConfilict();で$を変更
jQuery Mobileでのページ構造<div id="session_list" data-role="page"> <div data-role="header"> </div> <div data-role="content">
<a href="#session_detail">Session 1</a> </div> <div data-role="footer"> </div></div>
<div id="session_detail" data-role="page" data-add-back-btn="true"> <div data-role="header"> </div> <div data-role="content"> </div> <div data-role="footer"> </div></div>
• <div data-role="page">で1つの画面を表示• 1htmlファイルに複数の画面を記述可能。デフォルトでは最初のpageを表示。• ページ内リンク<a href="#{ID}">にて画面遷移。各<div>にid="{ID}"を設定しておく• data-add-back-btn="true"でヘッダにbackボタンを自動表示可能
リスト<div id="session_list" data-role="page" > <div data-role="header"><h1>セッションリスト</h1></div> <div data-role="content"> <ul data-role="listview" data-inset="true" data-filter="true"> <li><a href="#session1">Session 1</a></li> <li><a href="#session2">Session 2</a></li> <li><a href="#session3">Session 3</a></li> </ul> </div></div><div id="session1" data-role="page" data-add-back-btn="true"> <div data-role="header"><h1>セッション詳細</h1></div> <div data-role="content"> <ul data-role="listview"> <li data-role="list-divider">Session 1</li> <li>セッション 1の詳細</li> </ul> </div></div>
• <ul data-role=”listview”>でTouchに適したリストを表示• <ul data-filter=”true”>でリスト絞り込み用サーチボックスを表示• <li data-role=”list-divider”>でリストの見出を設定
サンプルアプリのトップページ<div id="session_list" data-role="page" data-theme="d"> <div data-role="header"> <h1>{!$label.sessionList}</h1> <a href="#create_session" class="ui-btn-right" data-icon="plus" data-transition="slideup">{!$label.new}</a> </div> <div data-role="content"> <ul data-role="listview" data-inset="true" data-divider-theme="d" data-filter="true" data-split-icon="gear"> <apex:repeat var="session" value="{!sessions}"> <li class="session">
<a href="/apex/sugoiSurveyM_detail?id={!session.id}" data-ajax="false"><h3>{!session.name}</h3><p>
{!session.presenter__r.company__c} {!session.presenter__r.title__c} {!session.presenter__r.name}<br /> {!YEAR(session.Date__c)}.{!MONTH(session.Date__c)}.{!DAY(session.Date__c)} #{!session.hash_tag__c}
</p> <span class="ui-li-count">{!session.rate_avg__c}pt</span>
</a><a href="/apex/sugoiSurveyM_edit?id={!session.id}" data-ajax="false"></a>
</li> </apex:repeat> </ul> </div></div>
データベース操作
JavaScript RemotingでApexを実行
j$('#submit_survey').tap(function(){ var rate = j$('input:radio:checked').val(); sugoiSurvey.submitSurveyJs( "{!session__c.id}", rate, function(result, event){ alert(event.message); }, {escape:true} );});
• sugoiSurvey.submitSurveyJs() => {Class名}.{Method名}()で対応するApexを実行• resultでクラスからの返り値を参照• eventでApexからの実行結果を参照
@RemoteActionpublic static void submitSurveyJs(id session, string rate){ survey__c survey = new survey__c(session__c = session, rate__c = rate); insert survey;}
Visulaforce Page
Apex
• @RemoteActionアノテーションを対応Methodに付加• global/publicかつstaticのMethodを定義
Database.com
認証
OAuth (PHP + REST)OAuth Toolkit for PHPをドキュメントルートに設置https://github.com/nkjm/Force.com-OAuth-Toolkit-for-PHP
•認証されているセッションは常に$_SESSION[‘access_token’]にTokenを保持• Tokenがなければ、
1.ローカルのOAuthライブラリにリダイレクト。2.Salesforceの認証サーバにリダイレクトされ、認証 => 「コード」取得。3.ローカルのOAuthライブラリにリダイレクト。SalesforceのTokenサーバからTokenを取得。4.$_SESSION[‘access_token’]にTokenを保存し認証下のコンテンツにリダイレクト。
<?phpsession_start();if (!isset($_SESSION['access_token']) || !isset($_SESSION['instance_url'])) { $_SESSION['oauth_return'] = $_SERVER['PHP_SELF'] . '?' . htmlspecialchars(SID); header( 'Location: /oauth/oauth.php?' . htmlspecialchars(SID));}
認証下に置くphpファイルの先頭
データベース操作
OAuth (PHP + REST)
$query = ‘select name from session__c’;$url = $_SESSION[‘instance_url’] . “/services/data/" . VERSION . "/query?q=" . urlencode($query);$curl = curl_init($url);curl_setopt($curl, CURLOPT_HEADER, false);curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);curl_setopt($curl, CURLOPT_HTTPHEADER, array("Authorization: OAuth “ . $_SESSION[‘access_token’]));$json_response = curl_exec($curl);$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);if ($status != 200) { if ($status == 401){ $response = json_decode($json_response); if ($response[0]->errorCode == 'INVALID_SESSION_ID') { header( 'Location: oauth/oauth.php' ); } } $curl_error = curl_error($curl); $curl_errno = curl_errno($curl); die("Status Code: $status <br/>Response: $json_response <br/> Curl Error: $curl_error <br/>Curl Errno: $curl_errno");}curl_close($curl);$response = json_decode($json_response, true);return($response);

// REST APIアクセスを抽象化するWrapperを初期化 var client = new forcetk.Client($client_id, null, $proxy_url);
// セッション情報をセット client.setSessionToken('<?php echo $_SESSION["access_token"]; ?>', null, '<?php echo $_SESSION["instance_url"]; ?>');
$('#account_form :button').click(function(){ var $account_name = $('#account_form :text').attr('value');
// createメソッドでAccountレコードを作成。第一引数はオブジェクト名。第二引数はフィールド。第三引数は成功時のコールバック。第四引数はエラー時のコールバック。 client.create( "Account", {"Name":$account_name}, function(response){ alert('Success!'); }, function(jqXHR){ alert(jqXHR.responseText); } ); }); });</script>
