Netconf 设置RPC返回list

.yang 文件

plugin 实现

1. 回调函数设置

rc = sr_rpc_subscribe_tree(session,"/oven:insert-food",oven_insert_food_tree_cb,NULL,SR_SUBSCR_CTX_REUSE,&subscription);
    if (rc != SR_ERR_OK)
    {
        goto error;
    }
           

2. 回调函数实现

static int oven_insert_food_tree_cb(const char *xpath, const sr_node_t *input, const size_t input_cnt,
        sr_node_t **output, size_t *output_cnt, void *private_ctx)
{
    sr_node_t *list = NULL, *leaf = NULL;
    int rc = SR_ERR_OK;
    
    rc = sr_new_trees(1, &(*output));
    if (SR_ERR_OK != rc) {
        return rc;
    }

    rc = sr_node_set_name(&(*output)[0], "result");
    if (SR_ERR_OK != rc) {
        return rc;
    }
    (*output)[0].type = SR_CONTAINER_T;

    for (size_t i = 0; i < 5; ++i) {
        /* - list instance */
        rc = sr_node_add_child(&(*output)[0], "user_module", NULL, &list);
        if (SR_ERR_OK != rc) {
            return rc;
        }

        list->type = SR_LIST_T;
        rc = sr_node_add_child(list, "name", NULL, &leaf);
        if (SR_ERR_OK != rc) {
            return rc;
        }
        sr_node_build_str_data(leaf, SR_STRING_T, "%c", 'A'+i);
        rc = sr_node_add_child(list, "age", NULL, &leaf);
        if (SR_ERR_OK != rc) {
            return rc;
        }
        leaf->type = SR_UINT8_T;
        leaf->data.uint8_val = i;
    }
    *output_cnt = 1;

    return rc;
}
           

NetOpeer2 调用以及返回

输入:

user-rpc
           

<insert-food xmlns="urn:sysrepo:oven">
    <time>on-oven-ready</time>
</insert-food>
           

输出:
