C++使用hiredis连接带密码的redis服务

 c = redisConnect((char*)redis_host, redis_port);
 if (c->err) {    /* Error flags, 0 when there is no error */
 printf("连接Redis失败: %s\n", c->errstr);
 exit();
 }
 else
 {
 printf("连接Redis成功！\n");
 }

 reply = (redisReply *)redisCommand(c, "AUTH %s", redis_password);
 if (reply->type == REDIS_REPLY_ERROR) {
 printf("Redis认证失败！\n");
 }
 else
 {
 printf("Redis认证成功！\n");
 }
 freeReplyObject(reply);

就是在正常连接服务后加上auth命令传入密码
