我想在 es6 模型中设置 JSON API,但收到此错误 类型错误:无法读取未定义的属性“first_name”
JSON API:
{ "type": "user", "id": 2, "attributes": { "username": "madelynn81", "email": "taylor63@mills.biz", "first_name": "Emile", "last_name": "Veum", "created_at": "2018-11-17 11:48:13" }, "links": { "self": "http://test.test/api/v1/user/2" } }
es6 model
class UserModel {
constructor(data) {
this.id = data.id;
this.first_name = data.attributes.first_name;
this.last_name = data.attributes.last_name;
this.username = data.attributes.username;
this.email = data.attributes.email;
this.created_at = data.attributes.created_at;
this.link = data.links.self;
}
get getId() {
return this.id;
}
set setId(value) {
this.id = value;
}
get getFirstName() {
return this.first_name;
}
set setFirstName(value) {
this.first_name = value;
}
get getLastName() {
return this.last_name;
}
set setLastName(value) {
this.last_name = value;
}
get getUsername() {
return this.username;
}
set setUsername(value) {
this.username = value;
}
get getEmail() {
return this.email;
}
set setEmail(value) {
this.email = value;
}
get getCreatedAt() {
return this.created_at;
}
set setCreatedAt(value) {
this.created_at = value;
}
get getLink() {
return this.link
}
set setLink(value) {
this.link = value
}
}
我该如何解决这个问题
最佳答案
从您的问题中不清楚您如何使用 getter 来获取值。一个问题:您的设置/获取对应该使用相同的属性名称来命名。它们的命名应与持有该值的属性不同。例如:_id
表示值属性名称,id
表示获取/设置名称。
class UserModel {
constructor(data) {
this._id = data.id;
this._firstName = data.attributes.first_name;
}
get id() {
return this.id;
}
set id(value) {
this._id = value;
}
get firstName() {
return this._firstName;
}
set firstName(value) {
this._firstName = value;
}
}
const data = {
"type": "user",
"id": 2,
"attributes": {
"username": "madelynn81",
"email": "taylor63@mills.biz",
"first_name": "Emile",
"last_name": "Veum",
"created_at": "2018-11-17 11:48:13"
},
"links": {
"self": "http://test.test/api/v1/user/2"
}
}
const user = new UserModel(data);
console.log(user.firstName)
