FAQ 常见问题Q1：这套系统可以商用吗？本文介绍的为内部演示环境，用于技术学习与功能验证。任何交易类系统商用前必须完成合规审查、资质办理、资金托管与安全审计。Q2：ThinkAdmin 和 FastAdmin 怎么选？ThinkAdmin v5：后台界面现代，适合管理功能复杂的 Web 平台FastAdmin：插件生态丰富，前后端分离支持好，适合带 API 的多端项目Q3：uni-app H5 如何对接 FastAdmin API？uni-app 通过 uni.request 请求 API 域名，FastAdmin 侧配置跨域或使用同域反向代理（如 /api 路径代理），登录后携带 token 访问业务接口。Q4：ThinkPHP 5.0.x......
