本文實例講述了php銀聯網頁支付實現方法。分享給大家供大家參考。具體分析如下：
這裡介紹的銀聯WAP支付功能，僅限消費功能。
1. PHP代碼如下：
復制代碼 代碼如下:<?php
namespace common\services;

*/

2. 配置示例
復制代碼 代碼如下://銀聯支付設置
'unionpay' => [
//測試環境參數
'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do', //前台交易請求地址
//'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do', //單筆查詢請求地址
'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/700000000000001_acp.pfx', //簽名證書路徑
'signCertPwd' => '000000', //簽名證書密碼
'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer', //驗簽證書路徑
'merId' => 'xxxxxxx',
//正式環境參數
//'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do', //前台交易請求地址
//'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do', //單筆查詢請求地址
//'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/PM_700000000000001_acp.pfx', //簽名證書路徑
//'signCertPwd' => '000000', //簽名證書密碼
//'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer', //驗簽證書路徑
//'merId' => 'xxxxxxxxx', //商戶代碼
],
3. 支付示例
復制代碼 代碼如下:$unionPay = new UnionPay();
$unionPay->config = Yii::$app->params['unionpay'];//上面的配置
$unionPay->params = [
'version' => '5.0.0', //版本號
'encoding' => 'UTF-8', //編碼方式
'certId' => $unionPay->getSignCertId(), //證書ID
'signature' => '', //簽名
'signMethod' => '01', //簽名方式
'txnType' => '01', //交易類型
'txnSubType' => '01', //交易子類
'bizType' => '000201', //產品類型
'channelType' => '08',//渠道類型
'frontUrl' => Url::toRoute(['payment/unionpayreturn'], true), //前台通知地址
'backUrl' => Url::toRoute(['payment/unionpaynotify'], true), //後台通知地址
//'frontFailUrl' => Url::toRoute(['payment/unionpayfail'], true), //失敗交易前台跳轉地址
'accessType' => '0', //接入類型
'merId' => Yii::$app->params['unionpay']['merId'], //商戶代碼
'orderId' => $orderNo, //商戶訂單號
'txnTime' => date('YmdHis'), //訂單發送時間
'txnAmt' => $sum * 100, //交易金額，單位分
'currencyCode' => '156', //交易幣種
];
$html = $unionPay->createPostForm();
4. 異步通知示例
復制代碼 代碼如下:$unionPay = new UnionPay();
$unionPay->config = Yii::$app->params['unionpay'];
$unionPay->params = Yii::$app->request->post(); //銀聯提交的參數
if(empty($unionPay->params)) {
return 'fail!';
}
if($unionPay->verifySign() && $unionPay->params['respCode'] == '00') {
//.......
}
希望本文所述對大家的php程序設計有所幫助。
