Question

有一个帖子请求

var a = [
  {name:'james',grade:'A'},
  {name:'john',grade:'B'},
  {name:'iris',grade:'A'},
  {name:'ivan',grade:'C'}
];

a.filter(function(e) { 
  return (e.grade == 'A') || (e.grade == 'C');
});

我在Angular 2中这样做，但她不工作，为什么？在请求中，我需要传输项目ID列表。作为回报，获取xls文件，但我无法做到。我发了一个帖子请求，但我无法将其翻译成Angular

var settings = {
  "async": true,
  "crossDomain": true,
  "url": "http://localhost:32001/api/job/jobs-list-excel",
  "method": "POST",
  "headers": {
    "content-type": "application/json",
    "cache-control": "no-cache",
    "postman-token": "9135e481-df69-b870-4f72-92873c1fd7de"
  },
  "processData": false,
  "data": "{\"jobIds\": [2,3]}"
}

$.ajax(settings).done(function (response) {
  console.log(response);
});

import {Headers, RequestOptions} from 'angular2/http';

    let body = JSON.stringify({ 'jobIds': '[2,3]' });
    let headers = new Headers({ 'Content-Type': 'application/json' },{'cache-control':'no-cache'},{'postman-token':'9135e481-df69-b870-4f72-92873c1fd7de'});
    let options = new RequestOptions({ headers: headers });
    let url = 'http://localhost:32001/api/job/jobs-list-excel';

    return this.http.post(url, body, options)
                    .map(res =>  res.json().data)
                    .catch(this.handleError)

将请求转换为Angular 2和Type Script
