印尼本地第三方支付Veritrans的ecshop插件

做一个印尼的ecshop二次开发，需要开发一个印尼本地的第三方支付的插件。印尼本地最大的线上支付是日本公司开发的Veritrans，Veritrans网址为：https://www.veritrans.co.id

以下是ecshop的完整代码：

第一步：在includes/modules/payment下，新建一个veritrans.php

<?php/** * veritrans 支付插件 * @author yuanjiang 04.29.2015 * @932625974#qq.com*/if (!defined('IN_ECS')){    die('Hacking attempt');}$payment_lang = ROOT_PATH . 'languages/' .$GLOBALS['_CFG']['lang'].

'" /></div>';}return $button;  }    /* respond */  public function respond(){ $action = $_REQUEST['action']; //notification if($action=='notification'){    $notif = new Veritrans_Notification();$order_id = $notif->order_id; } //finish else{    $order_id = $_REQUEST['order_id']; } $status = Veritrans_Transaction::status($order_id); $transaction = $status->transaction_status;     $fraud = $status->fraud_status; if ($transaction == 'capture') {    if ($fraud == 'challenge') {       // TODO Set payment status in merchant's database to 'challenge'    }    else if ($fraud == 'accept') {       // TODO Set payment status in merchant's database to 'success'   /* 检查支付的金额是否相符 */           if (!check_money($status->custom_field1, $status->gross_amount)){               return false;           }   else{       /* 改变订单状态 */               order_paid($status->custom_field1, PS_PAYED, $action_note = 'paid by veritrans at '.$status->transaction_time);               return true;   }    }     }     else if ($transaction == 'cancel') {    if ($fraud == 'challenge') {       // TODO Set payment status in merchant's database to 'failure'    }    else if ($fraud == 'accept') {       // TODO Set payment status in merchant's database to 'failure'    }     }     else if ($transaction == 'deny') {        // TODO Set payment status in merchant's database to 'failure'     } return false;  }}?>

第二步：为veritrans.php新建语言文件，在languages/en_us/payment下，新建veritrans.php

<?php/** * ECSHOP Veritrans language file * ============================================================================ * All right reserved (C) 2005-2011 Beijing Yi Shang Interactive Technology * Development Ltd. * Web site: http://www.ecshop.com * ---------------------------------------------------------------------------- * This is a free/open source software；it means that you can modify, use and * republish the program code, on the premise of that your behavior is not for * commercial purposes. * ============================================================================ * $Author: yuanjiang $ * $Id: veritrans.php 17217 2011-01-19 06:29:08Z yuanjiang $ */global $_LANG;$_LANG['veritrans']            = 'Veritrans';$_LANG['veritrans_desc']       = 'veritrans is the online payment for Indonesia eCommerce';$_LANG['veritrans_client_key']    = 'client key';$_LANG['veritrans_server_key']    = 'server key';$_LANG['pay_button']        = 'Pay in Veritrans immediately';?>

第三步：将veritrans的demo中的证书cacert.pem上传到ecshop的cert下，并改名为veritrans.pem

以上三步就完成了veritrans支付的全过程。
