php银联网页支付实现方法

  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.

  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:

  <?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>

  <p style="text-align:center">跳转中...</p>

  <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 ? 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

  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') {

  //.......

  }
