将以下配置文件用于您的代码中。

以下示例代码展示了如何使用 PHP 集成工具包。

步骤 1. 创建加密的支付请求，如示例文件所示。（payment.php）

		<?php
		require_once 'includes/BridgePGUtil.php';

		$bconn = new BridgePGUtil();
		$p = array(
		//  'csc_id' => $_SESSION['user']['username'],
			'csc_id' => $_SESSION['username'],
			'merchant_receipt_no' => 'Recpt#' . rand(100,999),
			'txn_amount' => $_GET['amt'],
			'return_url' => 'http://merchant.csccloud.in/pay_success.php',
			'cancel_url' => 'http://merchant.csccloud.in/pay_success.php',
			'txn_amount' => $_GET['amt'],
			'product_id' => '1112101',
			'merchant_txn' => 'MW' . rand(1000, 9999)
		);

		$bconn->set_params($p);
		$enc_text = $bconn->get_parameter_string();
		$frac = $bconn->get_fraction();
		?>


		  <form method="post" action="http://pay.csccloud.in/pay/m2b/<?php echo $frac;?>">
			   <input type="hidden" name="message" value="<?=$enc_text;?>" />
			   <input type="submit" value="Pay" />
		  </form>

• 以下为访问桥接器的封装器。（BridgePGUtil.php）

		<?php include_once __DIR__."/BridgePG.php";
		class BridgePGUtil {
		
		private $bridgePG;
		private $bridge_parameters;
		
		public function __construct(){
			$this->bridgePG = new BridgePG();
			$this->bridge_parameters = self::get_default_parameters();
		}
		
		private static function get_default_parameters(){
			$brj_params = array(
				'merchant_id'            => '11121',
				'merchant_txn'           => 'MDM101'.time(). rand(10,99),//'2016-06-21 18:11:58',
				'merchant_txn_date_time' => date('Y-m-d H:i:s'),//'2016-06-21 18:11:58',
				'product_id'             => '1112101',
				'product_name'           => 'my product',
				'txn_amount'             => '100',
				'amount_parameter'       => 'NA',
				'txn_mode'               => 'D',
				'txn_type'               => 'D',
				'merchant_receipt_no'    => '2016-06-21 18:11:58',
				'csc_share_amount'       => '0',
				'pay_to_email'           => 'a@abc.com',
				'return_url'             => '',
				'cancel_url'             => '',
				'Currency'               => 'INR',
				'Discount'               => '0',
				'param_1'                => 'NA',
				'param_2'                => 'NA',
				'param_3'                => 'NA',
				'param_4'                => 'NA'
			);
			return $brj_params;
		}
		
		public function set_params($params){
			foreach($params as $p => $v){
				$this->bridge_parameters[$p] = $v;
			}
		}

		public function get_parameter_string(){
			$message_text = '';
			foreach($this->bridge_parameters as $p => $v ){
				$message_text .= $p . '=' . $v . '|';
			}
			$message_cipher = $this->bridgePG->encrypt_message_for_wallet($message_text, FALSE);
			return $this->bridge_parameters['merchant_id'] . '|' . $message_cipher;
		}
		
		public function get_bridge_message(){
			$d = "Invalid Bridge message";
			if($_POST['bridgeResponseMessage']){
				$c = $this->bridgePG->decrypt_wallet_message($_POST['bridgeResponseMessage'], $d, FALSE);
			}
			return $d;
		}
		
		public function get_fraction($ddhhmm = ""){
			$time_format = "ymdHis";
			$algo_num    = "883";
			if(!$ddhhmm)
				$ddhhmm = date($time_format, time());
			$frac = $this->large_op1($ddhhmm, $algo_num );
			$frac = $this->large_op2($frac, "" . (1000 - $algo_num) );
			return $frac;
		}
		
		public function large_op1($n0, $x0){
			$n = '' . $n0;
			$x = '' . $x0;
			$sz = strlen('' . $n);
			$vals = array();
			$tens = 0;
			for($i = 0; $i < $sz; $i++ ){
				$d = $n[$sz - $i - 1];
				$res = $d * $x + $tens;
				$ones = $res % 10;
				$tens = (int)($res / 10);
				array_unshift($vals, $ones);
			}
			if($tens > 0)
				array_unshift($vals, $tens);
			return implode("", $vals);
		}
		
		public function large_op2($n0, $x0){
			$n = '' . $n0;
			$x = '' . $x0;
			$sz = strlen('' . $n);
			$vals = array();
			$tens = 0;
			for($i = 0; $i < $sz; $i++ ){
				$d = $n[$sz - $i - 1];
				if($i == 0)
					$res = $d + $x;
				else
					$res = $d + $tens;
				$ones = $res % 10;
				$tens = (int)($res / 10);
				array_unshift($vals, $ones);
			}
			if($tens > 0)
				array_unshift($vals, $tens);
			return implode("", $vals);
		} }   ?>

步骤 2. 处理支付响应以获取支付状态，如示例文件所示。（payment_response.php）

		<?php
		require_once 'includes/ BridgePGUtil.php';

		$bconn = new BridgePGUtil ();
		$bridge_message = $bconn->get_bridge_message();
		?>


		Encrypted Values:  <?php echo $_POST['bridgeResponseMessage']; ?>

		Decrypted Values: <?php $bridge_message; ?>
