angular - 如何在模型中定义嵌套对象？ (angular2/ typescript )

Question

我正在玩 Angular2，希望有人能就如何实现这一目标提供一些建议；

例如，如果我的模型当前对于员工看起来像这样:

export class Employee {
    constructor(
        public firstName: string,
        public lastName: string,
        public email: string,
        public days: string,
        public hours: string, 
    ){}
}

我想将天数/小时放入他们自己的对象中，这怎么可能实现？

(即喜欢..)

public availability: {
        public days: string,
        public hours: string
},

然后 http get 请求会像下面一样保持不变吗？

getEmployees() {
      return this.http.get('...')
             .map((response: Response) => {
                 const data = response.json().obj;
                 let objs: any[] = [];

                 for(let i = 0; i < data.length; i++) {
                     let employee = new Employee(
                     data[i].firstName,
                     data[i].lastName, 
                     data[i].email, 
                     data[i].availability.days,
                     data[i].availability.hours
                     );

                     objs.push(employee)
                 }
                 return objs
             })
          }

澄清一下，我希望我的 get 请求返回类似的东西；

var obj = {
    firstName: "test",
    lastName: "test",
    email: "test",
    availability: {
      days: "test",
      hours: "test"
    }
  }

希望有人能帮帮忙!我试着环顾四周，但没有发现任何可以提供帮助的东西。

类似这样的东西

export class Employee {
    constructor(
        public firstName: string,
        public lastName: string,
        public email: string,
        public availability: Availability // refer to type Availability  below
    ){}
}

export class Availability {
    constructor(
        public days: string,
        public hours: string
    ){}
}

Http get 请求应该保持不变，然后改变你创建新员工实例的方式

let employee = new Employee(
    data[i].firstName,
    data[i].lastName,
    data[i].email,
    new Availability(
          data[i].availability.days,
          data[i].availability.hours
    )
);
