命令行输入kvdb set key和程序代码写入的key，不是同一个

rt_bool_t auth_charge(void){
    char _auth_charge[1];
    rt_err_t res = get_env("auth_charge", _auth_charge);
    LOG_D("--------------> auth charge:%s, %d, %d", _auth_charge, res, strcmp(_auth_charge, "1"));
    if(res == RT_FALSE || RT_EOK == strcmp(_auth_charge, "1")){
        return RT_TRUE;
    }
    return RT_FALSE;
}

msh />kvdb set auth_charge 0
set the KV 'auth_charge', value is: 0
msh />kvdb show
