windows下使用redis c++

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

// MyRedisTest.cpp: 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include <assert.h>
#include <winsock2.h>
#include <string.h>
#include <tuple>
#include <iostream>
#include <sstream>
