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：
复制代码 代码如下:<"utf-8">
<title>支付</title>
</head>
<body>
<div style="text-align:center">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>
HTML;
/**
* 构建自动提交HTML表单
* @return string
*/
public function createPostForm()
{
$this->params['signature'] = $this->sign();
$input = '';
foreach($this->params as $key => $item) {
$input .= "\t\t<input type=\"hidden\" name=\"{$key}\" value=\"{$item}\">\n";
}
return sprintf($this->formTemplate, $this->config['frontUrl'], $input);
}
/**
* 验证签名
* 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；
* 用银联公钥对摘要和签名信息做验签操作
*
* @throws \Exception
* @return bool
*/
public function verifySign()
{
$publicKey = $this->getVerifyPublicKey();
$verifyArr = $this->filterBeforSign();
ksort($verifyArr);
$verifyStr = $this->arrayToString($verifyArr);
$verifySha1 = sha1($verifyStr);
$signature = base64_decode($this->params['signature']);
$result = openssl_verify($verifySha1, $signature, $publicKey);
if($result === -1) {
throw new \Exception('Verify Error:'.openssl_error_string());
}
return $result === 1 "codetitle">复制代码 代码如下://银联支付设置
'unionpay' => [
//测试环境参数
'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do', //前台交易请求地址
//'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do', //单笔查询请求地址
'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/700000000000001_acp.pfx', //签名证书路径
'signCertPwd' => '000000', //签名证书密码
'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer', //验签证书路径
'merId' => 'xxxxxxx',
//正式环境参数
//'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do', //前台交易请求地址
//'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do', //单笔查询请求地址
//'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/PM_700000000000001_acp.pfx', //签名证书路径
//'signCertPwd' => '000000', //签名证书密码
//'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer', //验签证书路径
//'merId' => 'xxxxxxxxx', //商户代码
],
3. 支付示例
复制代码 代码如下:$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') {
//.......
}
希望本文所述对大家的php程序设计有所帮助。
