《PHP实战：php银联网页支付实现方法》要点： PHP学习本篇章节讲解php银联网页支付实现方法.分享给大家供大家参考.具体分析如下： 1. PHP代码如下：
代码如下:
<?php

代码如下:
//银联支付设置
?'unionpay' => [ ???? //测试环境参数 ???? 'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do',//前台交易哀求地址 ???? //'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do',//单笔查询哀求地址 ???? 'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/700000000000001_acp.pfx',//签名证书路径 ???? 'signCertPwd' => '000000',//签名证书密码 ???? 'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer',//验签证书路径 ???? 'merId' => 'xxxxxxx', ???? //正式环境参数 ???? //'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do',//单笔查询哀求地址 ???? //'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/PM_700000000000001_acp.pfx',//签名证书路径 ???? //'signCertPwd' => '000000',//签名证书密码 ???? //'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer',//验签证书路径 ???? //'merId' => 'xxxxxxxxx',//商户代码 ?], 3. 支付示例????
代码如下:
$unionPay = new UnionPay();
$unionPay->config = Yii::$app->params['unionpay'];//上面的配置 $unionPay->params = [ ??? 'version' => '5.0.0',//版本号 ??? 'encoding' => 'UTF-8',//编码方式 ??? 'certId' => $unionPay->getSignCertId(),//证书ID ??? 'signature' => '',//签名 ??? 'signMethod' => '01',//签名方式 ??? 'txnType' => '01',//交易类型 ??? 'txnSubType' => '01',//交易子类 ??? 'bizType' => '000201',//产品类型 ??? 'channelType' => '08',//渠道类型 ??? 'frontUrl' => Url::toRoute(['payment/unionpayreturn'],true),//前台通知地址 ??? 'backUrl' => Url::toRoute(['payment/unionpaynotify'],//后台通知地址 ??? //'frontFailUrl' => Url::toRoute(['payment/unionpayfail'],//失败交易前台跳转地址 ??? 'accessType' => '0',//接入类型 ??? 'merId' => Yii::$app->params['unionpay']['merId'],//商户代码 ??? 'orderId' => $orderNo,//商户订单号 ??? 'txnTime' => date('YmdHis'),//订单发送时间 ??? 'txnAmt' => $sum * 100,//交易金额,单位分 ??? 'currencyCode' => '156',//交易币种 ]; $html = $unionPay->createPostForm(); 4. 异步通知示例
代码如下:
$unionPay = new UnionPay();
$unionPay->config = Yii::$app->params['unionpay']; $unionPay->params = Yii::$app->request->post(); //银联提交的参数 if(empty($unionPay->params)) { ??? return 'fail!'; } if($unionPay->verifySign() && $unionPay->params['respCode'] == '00') { ??? //....... } 希望本文所述对大家的php程序设计有所帮助. 《PHP实战：php银联网页支付实现方法》是否对您有启发，欢迎查看更多与《PHP实战：php银联网页支付实现方法》相关教程，学精学透。编程之家 52php.cn为您提供精彩教程。 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
