这篇文章主要介绍了php如何实现银联网页支付，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

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：

        支付    跳转中...
            %s    
    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) {            $input .= "\t\t\n";        }        return sprintf($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 ? true : false;}/*** 取签名证书ID(SN)* @return string*/public function getSignCertId(){        return $this->getCertIdPfx($this->config['signCertPath']);}  /*** 签名数据* 签名规则:* 除signature域之外的所有项目都必须参加签名* 根据key值按照字典排序，然后用&拼接key=value形式待签名字符串；* 然后对待签名字符串使用sha1算法做摘要；* 用银联颁发的私钥对摘要做RSA签名操作* 签名结果用base64编码后放在signature域** @throws \InvalidArgumentException* @return multitype|string*/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 $certdata['serialNumber'];}/*** 取.cer格式证书ID(SN)* @return string*/private function getCertIdCer($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

//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

$unionPay = new UnionPay();$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

$unionPay = new UnionPay();$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') {    //.......}
