打算轰轰烈烈地补一下框架内容，不想还没开张就熄火了

Package报错

错误信息

Assets\QFramework\Framework\0.Libs\3.Network\NetworkUtil.cs(82,20): error CS0619: 'Network' is obsolete: 'The legacy networking system has been removed in Unity 2018.2. Use Unity Multiplayer and NetworkIdentity instead.

意思就是不支持了，根据提示操作，竟然在2019.4找不到NetworkIdentity这个类，因为正在淘汰UNet，然后发现这个函数只为了得到IP地址，这就好办了，自己写一个不就行了。
