快速点击评论的 like 按钮会导致一次性点多个赞或扣多个赞，在前端甚至会产生负数。需要加个锁。

Problem description | Describe the bug

Quickly clicking the like button of a comment will result in multiple likes or deductions at once, and may even produce a negative number on the front end. Need to add a lock.

点赞和文章反应，以及浏览量等纯计数的能力，预期就是给网站增加氛围的，所以当时没有想做的很重，就是一个单纯的计数就好了。你说的这些问题其实都是已知的，暂时不打算通过锁的方式去修复。目前应该是增加了一个前端接口请求中点击无效的操作（不确定有没有）去规避下这个问题。另外就是很多 serverless 的数据库也没有锁的能力~

The ability to purely count likes, article reactions, and page views was expected to add atmosphere to the website, so I didn’t want to do anything heavy at that time, just a simple count. The problems you mentioned are actually known, and there are no plans to fix them through locking for the time being. At present, an invalid click operation in the front-end interface request should be added (not sure if it exists) to avoid this problem. In addition, many serverless databases do not have lock capabilities~
