C++ hiredis 写入数据时出现乱码

#include 
#include 
#include 
using namespace std;
int main() {
    const char* pwd = "redis";
    redisContext* ctx;
    redisReply* reply;
    ctx = redisConnect("127.0.0.1", 6379);
    if (ctx->err) {
        printf("Connection error:%sn", ctx->errstr);
        redisFree(ctx);
    }
    reply = (redisReply*)redisCommand(ctx, "auth %s", pwd);
    if (NULL == reply) {
        printf("Execut cmd failuren");
        redisFree(ctx);
    }
    string hval = "{"name":"xiaoming"}";
    reply = (redisReply*)redisCommand(ctx, "hset small_ship 9987777 %s", hval);
    cout << reply << endl;
    freeReplyObject(reply);
    return 0;
}

结果发现写入的Value变成乱码了：


把代码稍作修改
原来的代码：

    reply = (redisReply*)redisCommand(ctx, "hset small_ship 9987777 %s", hval);

修改成：

    reply = (redisReply*)redisCommand(ctx, "hset small_ship 9987777 %s", hval.c_str());

恢复正常
