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') {
    //.......
}
