Update to the latest 3.7

[cipchk]

我使用的是最新版本了，这个问题的根源还是因为参数 recvID 不允许为空字符，一但空字符 IM 服务器就崩了。

I am using the latest version. The root cause of this problem is that the parameter recvID does not allow null characters. Once the null character is used, the IM server will crash.

It is recommended to upgrade to v3.8. We have optimized the search and fixed this problem.
