转载 瞧瞧别人家的API接口，那叫一个优雅
在实际工作中，我们需要经常跟第三方平台打交道，可能会对接第三方平台API接口，或者提供API接口给第三方平台调用。那么问题来了，如果设计一个优雅的API接口，能够满足：安全性、可重复调用、稳定性、好定位问题等多方面需求？今天跟大家一起聊聊设计API接口时，需要注意的一些地方，希望对你会有所帮助。为了防止API接口中的数据被篡改，很多时候我们需要对API接口做。接口请求方将 + + 拼接成一个字符串，然后通过等hash算法，生成一个前面sign。然后在请求参数或者请求头中，增加sign参数，传递给API接口

转载 11.17复盘，虽然净值继续新高，但感觉状态不太行
然后讲一下现在医药的情况，核心中的核心是以岭药业，可以说以岭药业倒了，医药线的炒作就宣告结束，这点和众生药业那轮不一样，众生即使倒了，医药也不会倒，具体的逻辑写在隔壁星球了。写了很久的药房和维生素C今天终于是碰板了，第一医药，首板之前挖掘，浙江震元，也是前几天挖掘的，至于还能挖啥，好像真没思路了……b.半导体维持观点不变，继续看，医药如果弱了，半导体很有可能接棒，除了巴菲特和机构喊的周期，传闻还有政策补贴，重点看模拟芯片，然后光刻胶这块今天大涨是受传闻影响，看明天的持续性，首选应该还是模拟这块。

转载 Spring Boot 如何快速过滤出一次请求的所有日志？
本文讲述了如何使用MDC工具来快速过滤一次请求的所有日志，并通过装饰器模式使得MDC工具在异步线程里也能生效。有了MDC，再通过AOP技术对所有的切面植入requestId，就可以将整个系统的任意流程的日志过滤出来。使用MDC工具，在开发自测阶段，可以极大地节省定位问题的时间，提升开发效率；在运维维护阶段，可以快速地收集相关日志信息，加快分析速度。

转载 【干货】如何防止接口重复提交？（下）
在上一篇文章中，我们详细的介绍了随着下单流量逐渐上升，为了降低数据库的访问压力，通过请求唯一ID+redis分布式锁来防止接口重复提交，流程图如下！每次提交的时候，需要先调用后端服务获取请求唯一ID，然后才能提交。对于这样的流程，不少的同学可能会感觉到非常鸡肋，尤其是单元测试，需要每次先获取值，然后才能提交！能不能不用这么麻烦，直接服务端通过一些规则组合，生成本次请求唯一ID呢？答案是可以的！今天我们就一起来看看，如何通过服务端来完成请求唯一 ID 的生成？

转载 【干货】如何防止接口重复提交？（中）
在上一篇文章中，我们详细的介绍了对于下单流量不算高的系统，可以通过请求唯一ID+数据表增加唯一索引约束这种方案来实现防止接口重复提交！随着业务的快速增长，每一秒的下单请求次数，可能从几十上升到几百甚至几千。面对这种下单流量越来越高的场景，此时数据库的访问压力会急剧上升，上面这套方案全靠数据库来解决，会特别吃力！对于这样的场景，我们可以选择引入缓存中间件来解决，可选的组件有 redis、memcache 等。下面，我们以引入redis缓存数据库服务器，向大家介绍具体的解决方案！

转载 【干货】如何防止接口重复提交？（上）
对于投入运营的软件系统，最近小编在巡检项目数据库的时候，发现某些表存在不少的重复数据，对于这样的脏数据，初步分析大致的来源有以下可能：1.由于用户误操作，多次点击表单提交按钮2.由于网速等原因造成页面卡顿，用户重复刷新提交页面3.黑客或恶意用户使用 postman 等网络工具，重复恶意提交表单这些情况都可能会导致表单重复提交，造成数据重复，比如订单表，重复提交订单数据所造成的问题，可能不仅仅是数据上的混乱，也会造成业务混乱。那么问题来了，我们该如何防止用户重复提交数据呢？方案实践如下！
