pi支付流程图：
- 使用Pi SDK功能发起支付
- 由 Pi SDK 自动调用的回调函数（让您的应用服务器知道它需要发出批准 API 请求）
- 从您的应用程序服务器到 Pi 服务器的 API 请求以批准付款（让 Pi 服务器知道您知道此付款）
- Pi浏览器向用户显示付款详细信息页面，我们正在等待用户签署交易
- 由 Pi SDK 自动调用的回调函数（让您的应用服务器知道它需要发出完整的 API 请求）
- 从您的应用服务器到 Pi 服务器的 API 请求以完成付款（让 Pi 服务器知道您已完成此付款）

};详细流程
使用Pi-SDK功能发起支付
由Pi SDK自动调用的回调函数，发出支付批准请求
路由到后端的支付授权接口
后端服务器向Pi服务器发起支付授权

PI游览器向用户显示付款详细信息页面，我们等待用户签署交易
由Pi SDK自动调用完成的回调函数
从你的后端服务器到Pi服务器的API请求以完成付款（让pi服务器知道你完成此付款）

注意，如果用户有未处理的订单，会导致用户重新创建支付失败，需要有个接口去处理未完成的订单
前端一初始化就去执行处理未完成的订单
路由到后端的接口
