[Java] 歐付寶金流串接教學
前言：
很多接案的人，都會碰到需要接金流的時候。而歐付寶是個台灣的金流平台。
這邊記錄下，串接的心得。我用的語言是Java, 採liferay這個portal平台，不過這份教學當然適合servlet.
不過官方技術文件，太規格導向了。應該要方便developer快速開發才是 很多資訊還是要向官方問才知道。
流程 :
- 假設有一個網購網站，有使用者下了單之後，採用信用卡付款。此時照官方使用範例
會把所有資訊弄成html的語法(html hidden fields)，再加密送出去。
eg.<input type="hidden" name="Language" value="English"> -
如果不懂，覺得太抽象可以用 http://dev.lovewed.tw/allpay/ 這個網站來測試整個流程(歐付寶有提供測試平台，測試信用卡 卡號)。
了解整個流程後，我們可以確定歐付寶正常無誤就可以開始串寫程式了。
payment.jsp, 這支是負責user填完資料驗證後，且在我方server有紀錄後，送給轉到歐付寶付款用的。

則是user在歐付寶付款後，通知我方server用的，好讓我方server在資料庫中，紀錄成功入賬。
結尾：
基本上，只要欄位照著規格書填對。就沒有太大的問題，而看到官方有其他的問題則是參數中有 / - 等字串
所以過程中，我是已經避免此問題了。
若有問題，可以留言討論。
