在給app做支付寶支付介面的時候收集內容整理如下：

介面：

       import('alipay.AopClient', EXTEND_PATH);
        import('alipay.request.AlipayTradeAppPayRequest', EXTEND_PATH);

        $aop = new \AopClient();
        $aop->gatewayUrl = "https://openapi.alipay.com/gateway.do";
        $aop->appId = Config::get('alipay.app_id');
        $aop->rsaPrivateKey = Config::get('alipay.rsa_private_key');
        $aop->format = "json";
        $aop->charset = "UTF-8";
        $aop->signType = "RSA2";
        $aop->alipayrsaPublicKey = Config::get('alipay.alipay_rsa_public_key'); //Config::get('alipay.rsa_public_key'); //

        $request = new \AlipayTradeAppPayRequest();

        $bizcontent = json_encode([
            'body' => '紅包支付',
            'subject' => '使用者紅包支付',
            'out_trade_no' => $orderSn,
            'timeout_express' => '30m',
            'total_amount' => $amount,
            'product_code' => 'QUICK_MSECURITY_PAY'
        ]);

        $request->setNotifyUrl("https://" . $_SERVER['HTTP_HOST'] . "/api/callback/alipay");
        $request->setBizContent($bizcontent);//這裡和普通的介面呼叫不同，使用的是sdkExecute
        $response = $aop->sdkExecute($request);
        $return['aliresponse'] = $response;//htmlspecialchars($response);//htmlspecialchars是為了輸出到頁面時防止被瀏覽器將關鍵引數html轉義，實際列印到日誌以及http傳輸不會有這個問題
        $this->returnSuccess($return);
 

回撥處理：

    public function alipay()
    {
        import('alipay.AopClient', EXTEND_PATH);
        $aop = new \AopClient();
        $aop->alipayrsaPublicKey = Config::get('alipay.alipay_rsa_public_key');// file_get_contents($_SERVER['DOCUMENT_ROOT']."/key/alipay/alipay_public_key.txt");
        $flag = $aop->rsaCheckV1($_POST, NULL, "RSA2");
        if ($flag){
            //驗籤通過後核實如下引數trade_status、out_trade_no、total_amount、seller_id
            if (isset($_POST['trade_status']) && ($_POST['trade_status'] == 'TRADE_SUCCESS' || $_POST['trade_status'] == 'TRADE_FINISHED') ) {
                // 業務處理

                
            } else {
                $msg = var_export($_POST, true);
                $fileName = mt_rand(10,1000) .'00alisuccessAnother.log' ;
                file_put_contents($fileName, $msg);
            }
            echo "success";

        } else {
            $msg = var_export($_POST, true);
            $fileName = mt_rand(10,1000) .'00alicheckSignFail.log';
            file_put_contents($fileName, $msg);
        }
    }
