请问迭代器遍历的kv对象key的名字为空是什么原因？

[lilealyh]

void kvdb_tarversal_sample(fdb_kvdb_t kvdb) { struct fdb_kv_iterator iterator; fdb_kv_t cur_kv; struct fdb_blob blob; size_t data_size; uint8_t *data_buf;

fdb_kv_iterator_init(&iterator);

while (fdb_kv_iterate(kvdb, &iterator)) {
    cur_kv = &(iterator.curr_kv);
    data_size = (size_t) cur_kv->value_len;
    data_buf = (uint8_t *) malloc(data_size);
    if (data_buf == NULL) {
        rt_kprintf("Error: malloc failed.\n");
        break;
    }
    fdb_blob_read((fdb_db_t) kvdb, fdb_kv_to_blob(cur_kv, fdb_blob_make(&blob, data_buf, data_size)));
    /*
     * balabala do what ever you like with blob...
     */
    rt_kprintf("key:%s,data_buf:%s\n",cur_kv->name,data_buf);
    free(data_buf);
}

} rt_kprintf("key:%s,data_buf:%s\n",cur_kv->name,data_buf);//data_buf数据是对的，但是cur_kv->name打印为空

看一下cur_kv->name_len，我记得fdb的key string好像不保证'/0'结尾 rt_kprintf("%.*s :\r\n", cur_kv->name_len, cur_kv->name);
