對於PC版大尺吋的螢幕,當網站要 feed 資料到 facebook 時,可以使用 javascript SDK 的
FB.ui => method:'feed' 方式處理,參考位置。此方法會popup小視窗讓user可以分享資料出去。
但是遇到手機版網頁就有點麻煩,實測上手機版的 chrome 會出現轉不停的情況,無法分享;而iPhone則是另開新頁面處理,可以成功但是會多一個分頁。所以手機版網頁建議使用 redirect 方式處理分享機制,參考位置
var fbUrl = "https://www.facebook.com/dialog/feed?" +
"app_id=122465741241119&display=touch" +
"&link=" + encodeURIComponent("http://www.shopunt.com/tch/FixPage.aspx?id=525") +
"&picture=" + encodeURIComponent("http://www.shopunt.com/tch/event/2014-nail-enrollment/fb_200x200.jpg") +
"&description=" + encodeURIComponent("市價不斐的光療DIY教學,UNT傾囊相授!10場巡迴免費教學,讓妳輕鬆掌握光療DIY訣竅,並搶先體驗秋冬最新流行色!現場打卡,再送時尚美甲工具組") +
"&redirect_uri=" + encodeURIComponent("http://www.shopunt.com/tch/event/2014-nail-enrollment/Handler.ashx?fun=FBCallback");
當然以 redirect 處理與 javascript 方式處理是兩種不同的方式,redirect 方式的 callback 網址 (redirect_uri)要接收facebook 導回的 post_id , javascript 方式則是 callback function 處理 post_id
<link rel="stylesheet" type="text/css" href="style.css" media="screen" />
<script type="text/javascript" src="js/respond.min.js"></script>


<system.web>
<httpRuntime requestValidationMode="2.0" />
<pages validateRequest="false" />
</system.web>
後者比較算是正解 基本上處理掉 <script 我想 XSS 就解決一大半
