redis++的编译 安装 使用方案

小伙伴们对数据库编程感兴趣吗？是否正在学习相关知识点？如果是，那么本文《redis++的编译 安装 使用方案》，就很适合你，本篇文章讲解的知识点主要包括redis++。在之后的文章中也会多多分享相关知识点，希望对大家的知识积累有所帮助！

常见的是：hiredis 和hirredisvip

hiredis 和hirredisvip 都是最基础的。也没封装什么连接池啊，自动重连啊，那些东西。适合简单的场景。或者你自己手艺好，能自己封装一层好的接口。

后来尝试：cloredis

最后发现：redisplus plus

直到有一天我问同事，他们给我看redis官网推荐的C++的连接库，有好多库。好几页。而平时看的redis中文网推荐的才几个。艾玛。耽误事儿啊。

然后我接触了redisplus plus (redis++）。感觉蛮给力的玩意。

详细的信息可以看他们网站里的介绍。我这里只贴一段代码。
