新增檔案

在工程中新增redis的c語言客戶端檔案，linux無需win32fixes檔案

例子

#ifdef _WIN32
#include "hiredis.h"

#include <WinSock2.h>
#pragma comment(lib,"wsock32.lib")
#else
#include <sys/socket.h>
#include <sys/types.h>
#include <netinet/in.h>
 

#include <stdlib.h>
#include <errno.h>
#include <zlib.h>
#include <unistd.h>
#include <arpa/inet.h>  
#include "/home/redis/hiredis.h"

#endif
void main()
{
#ifdef _WIN32
	WORD wVerisonRequested;
	WSADATA wsaData;
	wVerisonRequested = MAKEWORD(1, 1);
	int err = WSAStartup(
 
wVerisonRequested, &wsaData);
	if (err != 0){
		return;
	}
#endif
	//初始化redis
	struct timeval t = { 15, 500000 }; 
	redisContext *pRedisContext = redisConnectWithTimeout("192.168.190.121", 6379, t);
	if (NULL == pRedisContext || pRedisContext->err)
	{       // redis為NULL與redis->err是兩種不同的錯誤，若redis->err為true，可使用redis->errstr檢視錯誤資訊  
 

	
		printf("%s \r\n", pRedisContext->errstr);
		printf("Connect to redisServer failed \n");
		return;
	}
	//輸入redis密碼
	const char* pcRedisPassWord = "password";
	pRedisReply = (redisReply *)redisCommand(pRedisContext, "AUTH %s", pcRedisPassWord);
	if (pRedisReply != NULL)
	{
		freeReplyObject(pRedisReply);
	}
	//用get命令獲取資料	
	sprintf(pcRedisBuff, "GET %s ", "keyName");
	pRedisReply = (redisReply *)redisCommand(pRedisContext, pcRedisBuff);
	if (pRedisReply == NULL)
	{

	{
		freeReplyObject(pRedisReply);
		return;
	}
	std::string strRes(pRedisReply->str);
	freeReplyObject(pRedisReply);
	//用set指令向redis寫入資料
	pRedisReply = (redisReply *)redisCommand(pRedisContext, "SET keyName value");
