php银联网页支付实现方法

本文实例讲述了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：

这里介绍的银联WAP支付功能，仅限消费功能。

1. PHP代码如下：

<?php

     * @var array
     */
    public $params = [];
    /**
     * 自动提交表单模板
     * @var string
     */

<!DOCTYPE HTML>
<html>
<head>
    <meta charset="utf-8">
    <title>支付</title>

<body>
    <div >跳转中...</div>
    <form id="pay_form" name="pay_form" action="%s" method="post">
        %s
    </form>
    <script type="text/javascript">
        document.onreadystatechange = function(){
            if(document.readyState == "complete") {
                document.pay_form.submit();
            }
        };
    </script>
</body>
</html>

2. 配置示例

复制代码代码如下:

//银联支付设置
\'unionpay\' => [
     //测试环境参数
     \'frontUrl\' => \'https://101.231.204.80:5000/gateway/api/frontTransReq.do\', //前台交易请求地址
     //\'singleQueryUrl\' => \'https://101.231.204.80:5000/gateway/api/queryTrans.do\', //单笔查询请求地址
     \'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\', //前台交易请求地址
     //\'singleQueryUrl\' => \'https://101.231.204.80:5000/gateway/api/queryTrans.do\', //单笔查询请求地址
     //\'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

复制代码代码如下:

$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\' => $unionPay->getSignCertId(), //证书ID
    \'signature\' => \'\', //签名
    \'signMethod\' => \'01\', //签名方式
    \'txnType\' => \'01\', //交易类型
    \'txnSubType\' => \'01\', //交易子类
    \'bizType\' => \'000201\', //产品类型
    \'channelType\' => \'08\',//渠道类型
    \'frontUrl\' => Url::toRoute([\'payment/unionpayreturn\'], true), //前台通知地址
    \'backUrl\' => Url::toRoute([\'payment/unionpaynotify\'], true), //后台通知地址
    //\'frontFailUrl\' => Url::toRoute([\'payment/unionpayfail\'], true), //失败交易前台跳转地址
    \'accessType\' => \'0\', //接入类型
    \'merId\' => Yii::$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

复制代码代码如下:

$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\') {
//.......
}
