在RxJS中组合两个对象

Question

我正在使用服务中的rxjs和angular 2.我有一些json,我可以通过get请求访问.

   private _campInfoUrl = 'api/campInfo/campInfo.json';
  constructor(private _http: Http) { }

  getAvailableCamps() {  
    return this._http.get(this._campInfoUrl)
      .map((response: Response) => response.json())

此时我掌握了所有数据.但要进入这个对象

      {
       "search": {
       "startDate": "2016-06-07",
       "endDate": "2016-06-10"
      },
       "reservations": [
       {"campsiteId": 1, "startDate": "2016-06-01", "endDate": "2016-06-04"},
       {"campsiteId": 1, "startDate": "2016-06-11", "endDate": "2016-06-13"},
       {"campsiteId": 2, "startDate": "2016-06-08", "endDate": "2016-06-09"}
  ] 
}

这就是我想要做的

.map((response: Response) => response.json()) // <IProduct[]>
  .map((tripDate) => ({
    reservations: tripDate.reservations,
    newRes: tripDate.search // <-- how to add this to every return object
  }))

我正在努力弄清楚的是rxjs如何在预留数组对象内"搜索"这样的方式

"reservations": [
 {
    "campsiteId": 1, 
    "startDate": "2016-06-01", 
    "endDate": "2016-06-04", 
     "searchStartDate": "2016-06-07, 
     "searchEndDate": "2016-06-10
 },
 {
    "campsiteId": 1, 
    "startDate": "2016-06-11", 
    "endDate": "2016-06-13",
    "searchStartDate": "2016-06-07, 
    "searchEndDate": "2016-06-10
 },
 {
   "campsiteId": 2, 
   "startDate": "2016-06-08", 
   "endDate": "2016-06-09",
   "searchStartDate": "2016-06-07, 
   "searchEndDate": "2016-06-10
 }

在上面的示例中,我将搜索对象添加到预留数组的每个索引中.

我希望这是连接或映射转换数组的问题.但是,我无法进入预留数组的每个索引

任何洞察导航这个json对象将不胜感激.

不知道为什么你不能"在每个索引里面",但你不必这样做,你甚至可以在没有RxJS的情况下做到这一点:

.map((response: Response) => response.json()) // <IProduct[]>
  .map((tripDate) => ({
    reservations: tripDate.reservations
      .map(reservation => Object.assign(
        {},
        reservation,
        {
          searchStartDate: tripDate.search.startDate,
          searchEndDate: tripDate.search.endDate
        }
      )
    )
  }))
