我實(shí)現(xiàn)了一個(gè)接口Fruit及其兩個(gè)實(shí)現(xiàn)：Apple和Banana。我想從 yaml 文件加載數(shù)據(jù)到兩個(gè)實(shí)現(xiàn)的對(duì)象中：capacity: 4Apple:- name: "apple1"  number: 1- name: "apple2"  number: 1Banana:- name: "banana1"  number: 2我實(shí)現(xiàn)了UnmarshalYaml將數(shù)據(jù)加載到對(duì)象中的接口：package mainimport (    "errors"    "gopkg.in/yaml.v3"    "log"    "fmt")type FruitBasket struct {    Capacity int `yaml:"capacity"`    Fruits []Fruit}func NewFruitBasket() *FruitBasket {    fb := new(FruitBasket)    return fb}type Fruit interface {    GetFruitName() string    GetNumber() int}type Apple struct {    Name string `yaml:"name"`    Number int `yaml:"number"`}type Banana struct {    Name string `yaml:"name"`    Number int `yaml:"number"`}func (apple *Apple) GetFruitName() string {    return apple.Name}func (apple *Apple) GetNumber() int {    return apple.Number}func (banana *Banana) GetFruitName() string {    return banana.Name}func (banana *Banana) GetNumber() int {    return banana.Number}type tmpFruitBasket struct {    Capacity int `yaml:"capacity"`    Fruits []map[string]yaml.Node}func (fruitBasket *FruitBasket) UnmarshalYAML(value *yaml.Node) error {    var tmpFruitBasket tmpFruitBasket    if err := value.Decode(&tmpFruitBasket); err != nil {        return err    }    fruitBasket.Capacity = tmpFruitBasket.Capacity    fruits := make([]Fruit, 0, len(tmpFruitBasket.Fruits))    for i := 0; i < len(tmpFruitBasket.Fruits); i++ {        for tag, node := range tmpFruitBasket.Fruits[i] {            switch tag {            case "Apple":                apple := &Apple{}                if err := node.Decode(apple); err != nil {                    return err                }                fruits = append(fruits, apple)            case "Banana":                banana := &Banana{}                if err := node.Decode(banana); err != nil {                    return err然而，這是行不通的。似乎Apple和Banana標(biāo)簽的數(shù)據(jù)未加載。Fruits可能是因?yàn)槲业慕Y(jié)構(gòu)中缺少切片的 yaml 標(biāo)志tmpFruitBasket。但是，作為Fruit一個(gè)接口，我無(wú)法定義 yaml 標(biāo)志。將來(lái)，我想實(shí)現(xiàn)代表具體水果（例如草莓）的其他結(jié)構(gòu)，實(shí)現(xiàn)該接口Fruit。關(guān)于如何解決這個(gè)問(wèn)題有什么想法嗎？
