快付生态系统积分交易核心源码段

快付生态系统重要单位是积分，积分的产出也是通过系统的任务模型来产生的。会员如果要获取更多的积分或者开启的任务需要的积分不够，那么就需要向平台的会员购买积分
会员之间积分互转涉及到自助模式，自助交易模式类似OTC挂单交易，这种挂单交易模式有一个好处是，平台作为托底担保方，会员之前转移的积分都经过平台的监管，这样也更高效便捷。
积分交易也是系统运营的核心功能，在此和大家一起分享下快付生态app积分交易核心源码端，系统开发交流李铁牛15889726201

系统积分交易购买流程：
1.卖家设积分挂单到系统公海
2.买家选择要购买积分单
3.卖家付款并上传付款凭证
4.卖家确认收款，并确认积分转出

以下是积分交易核心代码段
