* - 业务参数 JSON 序列化后，用随机 16 位密钥做 AES-128-ECB 加密（base64）放入 data；
|
||
* - AES 密钥用旺铺平台公钥 RSA 加密（base64）放入 signature；
|

* - 整体以 JSON 信封 POST：{serialNo, version, timestamp, data, signature, extras, organizNo}；
|
||
* - 应答/通知反向解密：商户私钥解 signature 得 AES 密钥，再用其解 data 得业务报文。
|
||
*
|
||
* 配置优先级：后台「系统设置 → 旺铺支付」(site_config wangpu.*) > config/services.php（env）
