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
namespacecommon\services;
classUnionPay
{
/**
*支付配置
*@vararray
*/
public$config=[];
/**
*支付参数，提交到银联对应接口的所有参数
*@vararray
*/
public$params=[];
/**
*自动提交表单模板
*@varstring
*/
private$formTemplate=<<<'HTML'
<!DOCTYPEHTML>
<html>
<head>
<metacharset="utf-8">
<title>支付</title>
</head>
<body>
<divstyle="text-align:center">跳转中...</div>
<formid="pay_form"name="pay_form"action="%s"method="post">
%s
</form>
<scripttype="text/javascript">
document.onreadystatechange=function(){
if(document.readyState=="complete"){
document.pay_form.submit();
}
};
</script>
</body>
</html>
HTML;

}

}

*验签规则：
*除signature域之外的所有项目都必须参加验签
*根据key值按照字典排序，然后用&拼接key=value形式待验签字符串；
*然后对待验签字符串使用sha1算法做摘要；

}2.配置示例
//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
$unionPay=newUnionPay();
$unionPay->config=Yii::$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
$unionPay=newUnionPay();
$unionPay->config=Yii::$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。
