/**
|
||
* 支付控制器
|
||
*
|
||
* 设计原则：核心只负责「订单/流程编排 + 事件触发」，具体支付方式由【支付插件】实现，
|
||
* 通过监听以下事件注入能力（插件在 info.php 的 events 中声明监听器即可）：
|
||
*
|
||
* - PaymentMethods 收集可用支付方式。监听器返回 array，如：
|
||
* [['code'=>'wechat','name'=>'微信支付','desc'=>'...','icon'=>'','sort'=>0], ...]
|
||
* - PaymentCreate 生成支付参数。监听器接收 ['order'=>[...],'params'=>[...]]，
|
||
* 返回网关参数 array（按需返回 null 表示不匹配该方法），如：
|
||
* ['type'=>'qrcode','qrcode_url'=>'weixin://...','expire'=>600]
|
||
* ['type'=>'redirect','redirect_url'=>'https://...']
|
||
* ['type'=>'form','html'=>'<form ...>']
|
||
* - PaymentNotify 异步回调。监听器接收 ['method'=>...,'request'=>[...],'get'=>[...]]，
|
||
* 完成验签与订单激活后，返回网关要求的响应字符串（如 'success'）。
|
||
* - PaymentFreeActive 免费套餐开通钩子（无支付）。
|
||
* - PaymentOrderCreate 订单落库钩子（插件可在此持久化订单）。
|
||
*
|
||
* 未安装任何支付插件时，create() 会返回「暂无可用支付方式」提示。
