写在前面
今天基本上睡了一天，下午起来后开始处理队友做完的登录注册模块与后面模块的联系。最后做完了“我的”模块。在写代码的过程中遇到了很多粗心的问题，也有很多底子不稳的问题。但主要还是业务逻辑没有理清。理清业务逻辑后基本写代码就一路顺畅了。到今天我负责的后台代码已经全部写完了，我算了算，大概一共2500行...其实真的写起来也感觉不到很多，主要还是业务逻辑要理清。
今日团队冲刺博客地址：https://www.cnblogs.com/three3/p/12756092.html
实现截图
登录和注册就不再演示了。
直接演示我的模块：
实现逻辑
整体的实现逻辑和之前类似,书写API，然后对API中获取的数据进行处理即可：

这里只贴一点
总结
今天大部分时间都在理清业务逻辑。也再次提醒我自己要好好思考后再下手。
