【记录】C语言使用hiredis存储结构体

记录一个hiredis使用结构体作为key，以及结构体为value的demo

#include <stdio.h>
#include <string.h>
#include <hiredis/hiredis.h>

typedef struct {
    char name[10];
    char myStr[20];
} mytest;

void test(void)
{
    redisContext *context = redisConnect("127.0.0.1", 6379);//默认端口，本机redis-server服务开启
    if(context->err) {
        //连接失败
        redisFree(context);
        printf("connect redisServer err:%s\n", context->errstr);
        return ;
    }

    printf("connect success\n");
    mytest test={0};
    memset(test.name, '\0', 10);
    strcpy(test.myStr, "llllll");

    mytest key={0};
    //strcpy(key.name, "123");
    strcpy(key.myStr, "strstr");

    char *key2 = strdup("test_key");
    printf("start set key value\n");
    redisReply *reply = (redisReply*)redisCommand(context, "SET %b %b",&key,sizeof(key),&test, sizeof(test));
    freeReplyObject(reply);

    reply = redisCommand(context, "GET %b", &key, sizeof(key));

    mytest *result = (mytest *)reply->str;
    printf("%s\n",result->name);
    printf("%s\n",result->myStr);
    freeReplyObject(reply);

}

int main(void)
{
    test();
    return 0;;
}

如果需要key为字符串类型的，只需要把key改为char数组，删除取地址符，value仍然不变即可
