流水文档 - 支付宝支付 (php)版本

laravel下接入支付宝，相对来说比较简单，简单记录下

1. 到支付宝商户页面申请应用及相关支付权限

获得如下

• APPID
• 公钥和私钥

2. 下载SDK

• 文档地址
• 将sdk导入到laravel，需要改2个地方
  • 一是AopClient有行代码有问题，注释掉
  • AopEncrypt.php里函数和Laravel的冲突了，我是把AopEncrypt干掉了

3. DEMO

APP，WEB，WAP三种目前，流程都是一样的

• 构造aopClient
• 构造对应request
• 发送到支付宝网关获得相关凭证
  • 对于web，wap直接echo即可。如果在微信客户端网页，支付宝文档上有说如果引导用户跳转到系统浏览器完成支付
  • 对于app返回给客户端，由客户端唤出支付宝app的支付流程

#  require alipay sdk

require_once ('alipay-sdk/aop/AopClient.php');
require_once ('alipay-sdk/aop/request/AlipayTradeAppPayRequest.php');
require_once ('alipay-sdk/aop/request/AlipayTradePagePayRequest.php');
require_once ('alipay-sdk/aop/request/AlipayTradeWapPayRequest.php');

        ];

        $request = new \AlipayTradeAppPayRequest();
        $response = $aopClient->sdkExecute($request);
        return $response;
    }
    
    
    private function createAliClient(){
        $c = new \AopClient();
        $c->gatewayUrl = PaymentController::config_ali_web['gateway'];
        $c->appId = PaymentController::config_ali_web['app_id'];
        # 把私钥放到storage下，之前直接写到.env会出现读取截断问题，放文件里保险
        $c->rsaPrivateKeyFilePath = storage_path(env("ALI_RSA_PATH",""));
        $c->format = "json";
        $c->charset= "UTF-8";
        $c->signType= "RSA2";
        # 公钥直接写到.env配置里
        $c->alipayrsaPublicKey = env("ALI_PUB","");
        return $c;
    }
}
