本文介绍支付宝中当面付下属的条码支付、扫码支付、订单查询、退款申请的集成开发过程。
本文分为以下五个部分：
条码支付和扫码支付介绍申请应用密钥生成及配置API及SDK集成条码支付、扫码支付、订单查询、退款申请
一、条码支付及二维码支付介绍
1. 条码支付
条码支付是支付宝给到线下传统行业的一种收款方式。商家使用扫码枪等条码识别设备扫描用户支付宝钱包上的条码/二维码，完成收款。用户仅需出示付款码，所有收款操作由商家端完成。其使用场景如下：
业务流程：
使用步骤：
用户登陆支付宝钱包，点击首页“付款”，进入付款码界面；收银员在商家收银系统操作生成订单，用户确认支付金额；用户出示钱包的“付款码”，收银员用扫码设备来扫描用户手机上的条码/二维码后，商家收银系统提交支付；付款成功后商家收银系统会拿到支付成功或者失败的结果。
2. 扫码支付
扫码支付，指用户打开支付宝钱包中的“扫一扫”功能，扫描商家展示在某收银场景下的二维码并进行支付的模式。该模式适用于线下实体店支付、面对面支付等场景。
其使用场景如下：
业务流程：
使用步骤：
用户登陆支付宝钱包，点击首页“付款-扫码付”，进入扫一扫界面；收银员在商家收银系统操作生成支付宝订单，用户确认支付金额，并生成二维码；用户使用钱包的“扫码付”，扫收银员提供的二维码，确认支付；用户付款后商家收银系统会拿到支付成功或者失败的结果。
二、接口申请
企业在申请企业支付宝之后，进行功能申请并签约，然后在蚂蚁金服开放平台中申请应用如下（详细过程就略了）
然后在功能列表中，申请当面付这一功能，申请成功后如下。
这样，我们就有了当面付的权限了。
三、密钥生成
在支付宝当面付的接口中，使用了非对称加密算法，商户自己的公钥和私钥需要自己使用OpenSSL手动生成。对这些概念比较陌生的话，请先自行先了解一下密码学的相关知识。OpenSSL也可以从方倍工作室博客中找到。
下载支付宝官方提供的密钥生成工具OpenSSL，然后执行以下命令就可以生成公钥和私钥。
其中
genrsa -out rsa_private_key.pem 1024
是用于生成RSA私钥，执行后在程序目录中生成一个文件rsa_private_key.pem，其内容如下
-----BEGIN RSA PRIVATE KEY-----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-----END RSA PRIVATE KEY-----
命令
rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
是用于生成RSA公钥，执行后在程序目录中生成一个文件rsa_public_key.pem，其内容如下
-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCyffRONGd8Q/1kRh1cpsSRi360DXLHI7zxdPJGYe5HKDWF7u9b3zZU9erZpM90XE7gZRKsxIgOurH4uqhmVRbto3e+LiYOyNpd6As3Q427KCTIT7ajhHicZ6GWhegTUiVLqiuWLsauQcbI6DO4GEZrlvAdzus0WcJiJOxW02rxSQIDAQAB-----END PUBLIC KEY-----
生成的这个RSA公钥，需要填写到应用中去，填写地址如下所示。私钥不需要填到配置中，到时候配置到代码中。
特别注意，密钥要去掉注释部分，且转换成一行字符，否则回车换行也成为密钥的一部分，将导致无法正常加解密。
同时，可以点击 “查看支付宝公钥”，将支付宝的公钥复制保存下来，后面的程序中将需要用到。
四、密钥生成API与密钥配置
公共参数
请求地址：公共请求参数：
请求参数
公共响应参数
响应参数
系统中配置如下
<?php$config = array ( //支付宝公钥'alipay_public_key' => "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDDI6d306Q8fIfCOaTXyiUeJHkrIvYISRcc73s3vF1ZT7XN8RNPwJxo8pWaJMmvyTn9N4HQ632qJBVHf8sxHi/fEsraprwCtzvzQETrNRwVxLO5jVmRGi60j8Ue1efIlzPXV9je9mkjzOmdssymZkh2QhUrCmZYI/FCEa3/cNMW0QIDAQAB",//商户私钥'merchant_private_key' => "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",//编码格式'charset' => "UTF-8",//支付宝网关'gatewayUrl' => "/gateway.do",//应用ID'app_id' => "061501500000",//异步通知地址,只有扫码支付预下单可用'notify_url' => "/alipay/notify.html",//最大查询重试次数'MaxQueryRetry' => "10",//查询间隔'QueryDuration' => "3");
其中支付宝公钥就是在前面中复制保存的，直接复制到程序中即可，而商户私钥是之前OpenSSL中生成的私钥。APPID是该服务的id号。
而这个异步通知将会接收扫码支付结果的通知。
五、条码支付、扫码支付、订单查询、退款申请
1. 条码支付
条码支付的参数配置如下
// (必填) 商户网站订单系统中唯一订单号，64个字符以内，只能包含字母、数字、下划线，// 需保证商户系统端不能重复，建议通过数据库sequence生成，$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
