支付宝支付开发――当面付条码支付和扫码支付实例

系统中配置如下

<?php
$config = array ( 
 //支付宝公钥
 'alipay_public_key' => "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDDI6d306Q8fIfCOaTXyiUeJHkrIvYISRcc73s3vF1ZT7XN8RNPwJxo8pWaJMmvyTn9N4HQ632qJBVHf8sxHi/fEsraprwCtzvzQETrNRwVxLO5jVmRGi60j8Ue1efIlzPXV9je9mkjzOmdssymZkh2QhUrCmZYI/FCEa3/cNMW0QIDAQAB",

 //商户私钥
 'merchant_private_key' => "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",

 //编码格式
 'charset' => "UTF-8",

 //支付宝网关
 'gatewayUrl' => "https://openapi.alipay.com/gateway.do",

 //应用ID
 'app_id' => "2016061501500000",

 //异步通知地址,只有扫码支付预下单可用
 'notify_url' => "http://www.fangbei.org/alipay/notify.html",

 //最大查询重试次数
 'MaxQueryRetry' => "10",

 //查询间隔
 'QueryDuration' => "3"
);

其中支付宝公钥就是在前面中复制保存的，直接复制到程序中即可，而商户私钥是之前OpenSSL中生成的私钥。APPID是该服务的id号。

而这个异步通知将会接收扫码支付结果的通知。

五、条码支付、扫码支付、订单查询、退款申请

1. 条码支付

条码支付的参数配置如下

// (必填) 商户网站订单系统中唯一订单号，64个字符以内，只能包含字母、数字、下划线，
// 需保证商户系统端不能重复，建议通过数据库sequence生成，
$outTradeNo = "barpay" . date('Ymdhis') . mt_rand(100, 1000);
$subject = "方倍工作室-支付宝-当面付-扫码支付";
$totalAmount = 0.01; // (必填) 订单总金额，单位为元，不能超过1亿元

// (必填) 付款条码，用户支付宝钱包手机app点击“付款”产生的付款条码
$authCode = $_POST['auth_code']; //28开头18位数字

// 支付超时，线下扫码交易定义为5分钟
$timeExpress = "5m";

// 创建请求builder，设置请求参数
$barPayRequestBuilder = new AlipayTradePayContentBuilder();
$barPayRequestBuilder->setOutTradeNo($outTradeNo);
$barPayRequestBuilder->setTotalAmount($totalAmount);
$barPayRequestBuilder->setAuthCode($authCode);
$barPayRequestBuilder->setTimeExpress($timeExpress);
$barPayRequestBuilder->setSubject($subject);
// 调用barPay方法获取当面付应答
$barPay = new AlipayTradeService($config);
$barPayResult = $barPay->barPay($barPayRequestBuilder);

switch ($barPayResult->getTradeStatus()) {
 case "SUCCESS":
  echo "支付宝支付成功:" . "<br>--------------------------<br>";
  print_r($barPayResult->getResponse());
  break;
 case "FAILED":
  echo "支付宝支付失败!!!" . "<br>--------------------------<br>";
  if (!empty($barPayResult->getResponse())) {
   print_r($barPayResult->getResponse());
  }
  break;
 case "UNKNOWN":
  echo "系统异常，订单状态未知!!!" . "<br>--------------------------<br>";
  if (!empty($barPayResult->getResponse())) {
   print_r($barPayResult->getResponse());
  }
  break;
 default:
  echo "不支持的交易状态，交易返回异常!!!";
  break;
}
 return;
}

程序监测，最终提交的url如下

$qrPayRequestBuilder->setTimeExpress($timeExpress);
$qrPayRequestBuilder->setSubject($subject);

// 调用qrPay方法获取当面付应答
$qrPay = new AlipayTradeService($config);
$qrPayResult = $qrPay->qrPay($qrPayRequestBuilder);

// 根据状态值进行业务处理
switch ($qrPayResult->getTradeStatus()){
 case "SUCCESS":
  echo "支付宝创建订单二维码成功:"."<br>---------------------------------------<br>";
  $response = $qrPayResult->getResponse();
  $qrcode = $qrPay->create_erweima($response->qr_code);
  echo $qrcode;
  print_r($response);
