为同一个对象分配不同的接口
我有一个 Typescript 项目，我想在具有不同接口的多个函数之间传递相同的对象，
这些是接口：
export interface TestModel {
fileName:string,
year:number,
country:string
}
export interface Test2Model {
fileName:string,
year:number
}
这是生成对象的第一个函数，并调用第二个函数，将生成的对象传递给它：
function test1() {
let fileData:TestModel = {
fileName:'fileName',
year:2022,
country:'Spain'
}
test2(fileData)
}
test1();
这是第二个函数函数：
function test2(fileData:Test2Model) {
console.log(fileData)
}
这是我在第二个函数中得到的：
{fileName: "fileName", year: 2022, country: "Spain"}
这是我想要收到的：
{fileName: "fileName", year: 2022}
我的问题：是否可以自动生成适应 Test2Model 接口的第二个对象而不创建新对象？
I have a Typescript project in which I want to pass the same object between several functions with a different interface
These are the interfaces:
export interface TestModel {
fileName:string,
year:number,
country:string
}
export interface Test2Model {
fileName:string,
year:number
}
This is the first function that generates the object and calls the second function passing it the generated object:
function test1() {
let fileData:TestModel = {
fileName:'fileName',
year:2022,
country:'Spain'
}
test2(fileData)
}
test1();
This is the second function:
function test2(fileData:Test2Model) {
console.log(fileData)
}
This is what I get in the second function:
{fileName: "fileName", year: 2022, country: "Spain"}
This is what I want to receive:
{fileName: "fileName", year: 2022}
My problem: is it possible to automatically generate the second object adapted to the Test2Model interface without creating a new object?

你需要删除属性，类型不能改变对象。使用删除关键字，例如
You need to delete the property, the type can't change the object. Use delete keyword like
