简介: 记录个人,家庭等财务收支情况,可免费导出收支明细,与家人好友共享账本,让记账变得更简单
我的个人blog网站:https://www.zhooson.cn/ 里面其他全栈项目开源Github地址
前端:uniapp(vue3)
后端:egg
node:16.5.0
数据库:mysql
工具:HbuilerX filezilla pm2 Termius等
具体的开发文档:https://uniapp.dcloud.net.cn/
技术选型:uniapp以前没有使用过,这次决定尝试一次。
使用感觉,感觉不咋好,也许我是了解的不够全面,我每次小程序开发工具添加新的编译模式,重新打包后就没有了,这一点软件默认设置不太友好。
uniapp仔细阅读文档即可,本文不做详细讲解。
jwt
使用 yarn add egg-jwt

};
// {app_root}/app/controller/user.js
//签发 token 数据...let result = await service.user.query({ openId });const token = app.jwt.sign({nickname: result.openId,userId: result.id,exp: Math.floor(Date.now() / 1000) + 60 * 60, // 1h},app.config.jwt.secret);

我的sql语法不太完美,请大神提出宝贵意见。
