Vendor('alipaysdk.AopSdk');
$aop = new AopClient;
$aop->gatewayUrl = C('ALI_GATE_WAY_URL');
$aop->appId = C('ALI_APPID');
$aop->rsaPrivateKey = C('ALI_RSAPRIVATEKEY');
$aop->alipayrsaPublicKey = C('ALI_NOTIFY_RSAPRIVATEKEY');//这个是支付宝的公钥
$aop->apiVersion = '1.0';
$aop->signType = "RSA2";
$aop->charset = "utf-8";
$aop->format = "json";
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay
$request = new AlipayTradeRefundRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数
$bizcontent = "{\"out_trade_no\":\"" . $wxpay_info['out_trade_no'] . "\","
        . "\"refund_amount\": \"" . $wxpay_info['money'] . "\","
        . "\"refund_reason\":\"预约订单退款\""//注意这里不能有逗号
        . "}";
$request->setBizContent($bizcontent);
$result = $aop->execute($request);
$responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";
$resultCode = $result->$responseNode->code;
$refund_fee = $result->$responseNode->refund_fee;
