这篇文章主要介绍了php银联网页支付实现方法,实例分析了php操作银联网支付接口的技巧,具有一定参考借鉴价值,需要的朋友可以参考下

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

namespace common\services;

class UnionPay

{

    /**

     * 支付配置

     * @var array

     */

    public $config = [];

    /**

     * 支付参数，提交到银联对应接口的所有参数

     * @var array

     */

    public $params = [];

    /**

     * 自动提交表单模板

     * @var string

     */

    private $formTemplate = <<<'HTML'

<!DOCTYPE HTML>

<html>

<head>

    <meta charset="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 ? true : false;

}

/**

*/

public function getSignCertId()

{

        return $this->getCertIdPfx($this->config['signCertPath']);

}   

/**

*/

private function sign() {

        $signData = $this->filterBeforSign();

        ksort($signData);

        $signQueryString = $this->arrayToString($signData);

        if($this->params['signMethod'] == 01) {

            //签名之前先用sha1处理

            //echo $signQueryString;exit;

            $datasha1 = sha1($signQueryString);

            $signed = $this->rsaSign($datasha1);

        } else {

            throw new \InvalidArgumentException('Nonsupport Sign Method');

        }

        return $signed;

}

/**

* 数组转换成字符串

* @param array $arr

* @return string

*/

private function arrayToString($arr)

{

        $str = '';

        foreach($arr as $key => $value) {

            $str .= $key.'='.$value.'&';

        }

        return substr($str, 0, strlen($str) - 1);

}

/**

* 过滤待签名数据

* signature域不参加签名

* 

* @return array

*/

private function filterBeforSign()

{

        $tmp = $this->params;

        unset($tmp['signature']);

        return $tmp;

}

/**

* RSA签名数据，并base64编码

* @param string $data 待签名数据

* @return mixed

*/

private function rsaSign($data)

{

        $privatekey = $this->getSignPrivateKey();

        $result = openssl_sign($data, $signature, $privatekey);

        if($result) {

            return base64_encode($signature);

        }

        return false;

}

/**

* 取.pfx格式证书ID(SN)

* @return string

*/

private function getCertIdPfx($path)

{

        $pkcs12certdata = file_get_contents($path);

        openssl_pkcs12_read($pkcs12certdata, $certs, $this->config['signCertPwd']);

        $x509data = $certs['cert'];

        openssl_x509_read($x509data);

        $certdata = openssl_x509_parse($x509data);

        return $certdata['serialNumber'];

}

/**

* @return string

*/

private function getCertIdCer($path)

{

        $x509data = file_get_contents($path);

        openssl_x509_read($x509data);

        $certdata = openssl_x509_parse($x509data);

        return $certdata['serialNumber'];

}

/**

* 取签名证书私钥

* @return resource

*/

private function getSignPrivateKey()

{

        $pkcs12 = file_get_contents($this->config['signCertPath']);

        openssl_pkcs12_read($pkcs12, $certs, $this->config['signCertPwd']);

        return $certs['pkey'];

}

/**

* 取验证签名证书

* @throws \InvalidArgumentException

* @return string

*/

private function getVerifyPublicKey()

{

        //先判断配置的验签证书是否银联返回指定的证书是否一致

        if($this->getCertIdCer($this->config['verifyCertPath']) != $this->params['certId']) {

            throw new \InvalidArgumentException('Verify sign cert is incorrect');

        }

        return file_get_contents($this->config['verifyCertPath']);       

    }

}

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') {

    //.......

}
