沙箱环境管理

<?php

// 沙箱模式下创建订单不会扣真实资金
$wechat = Pay::wechat([...]);
$result = $wechat->createOrder([...]);

事件系统

<?php

use Kode\Pays\Facade\Pay;
use Kode\Pays\Event\Events;

// 注册支付成功监听器
Pay::on(Events::PAYMENT_SUCCESS, function (array $payload) {

    $amount  = $payload['amount'];

    // 发送支付成功通知（邮件/短信/站内信）
    // 与支付逻辑完全解耦
});

// 注册异常监听器
Pay::on(Events::EXCEPTION_OCCURRED, function (array $payload) {
    $exception = $payload['exception'];

    // 上报监控（Sentry/钉钉/企业微信）

    echo '<xml><return_code><![CDATA[SUCCESS]]></return_code></xml>';
} else {
    echo '<xml><return_code><![CDATA[FAIL]]></return_code></xml>';
}

协程并发处理（需安装 kode/fibers 或 Swoole）

<?php

use Kode\Pays\Async\AsyncNotifyHandler;
use Kode\Pays\Facade\Pay;

$handler = new AsyncNotifyHandler();

// 批量并发处理通知
$tasks = [
