这是一个内部收单系统，依赖 yansongda/pay 这个组件，本收单系统，统一了调用。 备注，交易单位是分；

环境需求
----

[](#环境需求)

- PHP >= 7.4.0

安装
--

[](#安装)

```
# yansongda/pay 2.x
composer require "larva/think-transaction:^2.0"

# yansongda/pay 3.x
composer require "larva/think-transaction:^3.0"
```

由于 `ThinkPHP` 不支持发布迁移文件到应用目录，所以你需要手动复制迁移文件到你应用的迁移目录后执行迁移； 迁移文件在 `vendor/larva/think-transaction/migrations` 下；

事件

```
\Larva\Transaction\Events\ChargeClosed 交易已关闭
\Larva\Transaction\Events\ChargeFailed 交易失败
\Larva\Transaction\Events\ChargeSucceeded 交易已支付
\Larva\Transaction\Events\RefundFailed 退款失败事件
\Larva\Transaction\Events\RefundSucceeded 退款成功事件
\Larva\Transaction\Events\TransferFailed 企业付款（提现）失败事件
\Larva\Transaction\Events\TransferSucceeded 企业付款（提现）成功事件
```

你自己的订单关联参考下面的类，总体思路是你自己的订单模型或者其他需要用户付款的模型在模型创建后你可以用创建后事件来调用付款； 需要在前端或者APP端执行付款逻辑的时候，你只需要 `$model->charge->getCredential();`就能获取到付款参数，带入对应的SDK即可，比如APP的SDK需要的几个参数，这里都能获取到。 `\Larva\Transaction\Events\ChargeSucceeded` 事件你可以监听到付款成功的事件， 你只需判断事件的source属性是否是你当前这个模型的实例即可知道是谁触发了付款并且付款成功；

创建一个事件监听器 `php think make:subscribe ChargeShipped`

```
