redis是高效key-value NOSQL 数据库 代码开源
windows下使用需要使用微软在redis官方上的改进版
地址 https://redis.io/download
寻找windows的版本
https://github.com/MicrosoftArchive/redis
我这里下载的是windows版本redis 3.0版本 使用vs2017编译
由于是微软官方的redis改变版本 使用VS编译基本无问题
如图
需要注意的是hiredis工程 生成的是LIB文件供其他连接redis的项目使用
但是该工程调用了Win32_Interop项目代码，所以使用时候需要同时提供Win32_Interop.lib hiredis.lib。
此时项目编译的结果应该是 成功编译redis-server.exe 并且有Win32_Interop.lib hiredis.lib可供我们编写客户端使用。
参考 https://www.cnblogs.com/chinxi/p/6184885.html 添加模板结构
客户端的编写
新建工程。工程里面放入 Win32_Interop.lib hiredis.lib
加入 hiredis相关和Win32_Interop相关头文件
注意 hiredis.h头文件中
#include "../../src/Win32_Interop/win32_types_hiredis.h"
两个头文件的相对路径可能需要修改
代码如下
