如何在模型中定义嵌套对象？(angular2 /打字稿)

Question

我正在玩Angular2,并希望有人可以提供一些如何实现这一目标的建议;

例如,如果我的模型目前对于员工来说是这样的:

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

我希望将天/小时放入他们自己的物体中,怎么可能实现呢？

(比如..)

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

然后http get请求保持不变如下所示？

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
             })
          }

只是为了澄清,我希望我的请求返回类似的东西;

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

希望有人可以帮忙!我试图环顾四周,但没有遇到任何有用的东西.

像这样的东西

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请求应保持不变,然后更改您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
    )
);
