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：

1.  条码支付和扫码支付介绍
2.  申请应用
3.  密钥生成及配置
4.  API及SDK集成
5.  条码支付、扫码支付、订单查询、退款申请

注： 支付宝支付开发有一定的门槛，如果您愿意为知识付费来节省您宝贵的时间，请直接见底部说明。

## 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：

![340216-20160826155828991-721930105.png][]

使用步骤：

1.  用户登陆支付宝钱包，点击首页“付款”，进入付款码界面；
2.  收银员在商家收银系统操作生成订单，用户确认支付金额；
3.  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；
4.  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：

1.  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；
2.  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；
3.  用户使用钱包的“扫码付”，扫收银员提供的二维码，确认支付；
4.  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）

![340216-20160826151105397-683705404.png][]

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。

![340216-20160826152344038-1826089701.png][]

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

![复制代码][copycode.gif]

![复制代码][copycode.gif]

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

![复制代码][copycode.gif]

![复制代码][copycode.gif]

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。

![340216-20160826153147288-196263525.png][]

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。

![340216-20160826153923554-1289835436.png][]

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 ##

系统中配置如下

 $config = array (

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

![复制代码][copycode.gif]

// (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-条码支付";
 $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 ($barPayResult->getTradeStatus()) {
 case "SUCCESS":
 echo "支付宝支付成功:" . " -------------------------- ";
 print_r($barPayResult->getResponse());
 break;
 case "FAILED":
 echo "支付宝支付失败!!!" . " -------------------------- ";
 if (!empty($barPayResult->getResponse())) {
 print_r($barPayResult->getResponse());
 }
 break;
 case "UNKNOWN":
 echo "系统异常，订单状态未知!!!" . " -------------------------- ";
 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;
 }
