之前有一次提交项目代码，代码在被我提交到暂存区并commit了以后，因为有个eslint语法不规范的地方，所以导致了precommit失败。结果不知道什么原因precommit失败之后，暂存区的代码丢失不见了。
因为是在visual studio的可视化git工具上进行的操作，初步怀疑是vs可视化工具的偶发bug，但目前还没有定论，只能是下次多注意了。

当时找回代码花了很大的功夫，特此记录一下，以防下次再发生相同的事情。

1. 运行这条git指令可以查看暂存区的存储记录，50q即指50条存储记录
   find .git/objects -type f | xargs ls -lt | sed 50q

2. 运行这条指令可以生成当时这条暂存区存储记录下存储的代码文件
   git cat-file -p 3f623a8da5f8703b46c74db93a8ee70753eee0fc > ResultFile

（查询记录要去掉斜杠：3f/623a8da5f8703b46c74db93a8ee70753eee0fc => 3f623a8da5f8703b46c74db93a8ee70753eee0fc，ResultFile是生成文件名）

下方为生成文件的目录，然后就根据目录找回相应代码了
