使用rxjs将json响应映射到嵌套typescript对象

{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
}

class Person {
  name: string;
  age: number;
  address: Address;
}

class Address {
  street: string;
  city: string;
}

import { map } from 'rxjs/operators';

// 假设jsonResponse是从服务器获取的json响应
const jsonResponse = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
};

const person$ = of(jsonResponse).pipe(
  map((response: any) => {
    const person = new Person();
    person.name = response.name;
    person.age = response.age;

    const address = new Address();
    address.street = response.address.street;
    address.city = response.address.city;

    person.address = address;

    return person;
  })
);

person$.subscribe((person: Person) => {
  console.log(person);
});
