Javascript 将请求转换为Angular 2并键入脚本

Javascript 将请求转换为Angular 2并键入脚本,javascript,angular,typescript,Javascript,Angular,Typescript,有一个Post请求 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-tok

有一个Post请求

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);
});
我在Angular 2中做,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,但我不能这样做。我提出了一个post请求,但我无法将其转换为一个角度

 public GetJobsListExcel(jobs: JobViewModel[]): Promise<Result> {
        var JobIds: number[] = [];
        var headers = new Headers();
        headers.append('Content-Type', 'application/json')
        jobs.forEach(x => JobIds.push(x.JobId));

        return this.http.post(this.jobsUrl + "/jobs-list-excel",
            {
                jobIds: JobIds,
            },
            {
                headers: headers
            })
            .toPromise()  
            .then(response => response.json() as Result);
    }
公共GetJobsListExcel(作业:JobViewModel[]):承诺{ var JobIds:number[]=[]; var headers=新的headers(); headers.append('Content-Type','application/json') jobs.forEach(x=>JobIds.push(x.JobId)); 返回this.http.post(this.jobsUrl+“/jobslist excel”, { jobIds:jobIds, }, { 标题:标题 }) .toPromise() .then(response=>response.json()作为结果); }
以JSON.stringify({jobIds:jobIds})的形式发送数据与您在上面的post请求中发送数据的方式相同。那么最后一个请求的内部响应是什么?你能
console.log(response)
并报告结果吗。还将拒绝处理程序和console.log()放在那里。更改
.then(response=>response.json()作为结果)console.log(response),err=>console.log(err))然后您可以返回报告。我看不到您要在
标题
