Question

我有以下标题

var headers = new HttpHeaders();            
    headers.set('Content-Type', 'application/json');
    headers.set('X-Quikr-App-Id', '1087');
    headers.set('X-Quikr-Token-Id', '785582933');
    headers.set('X-Quikr-Signature-v2', '86742d91e19bc30cdd923bf6a84194c133570659');
    headers.set('Access-Control-Allow-Origin', '*');


this.http.get('https://api.quikr.com/public/adsByLocation?lat=28.64649963&lon=77.22570038&from=0&size=1', {
                     headers:headers })
  .subscribe(

这是一个例外，而当我从Postman那里做同样的事情时，它正在发挥作用。这里奇怪的是，当我从我的应用程序运行此操作时，我只在选项中出现错误，即即使调用了get调用，我也无法在响应中看到任何标题。
任何人都可以建议我帮忙。谢谢。

Answer 1

不要将该套装分开，只需

$(".stayalert_checkbox").on('click',function(){
  if($(this).prop("checked",false)){
    $(this).prop("checked",true)
    $("#stay_alert_div").toggle();
  }else{
    $(this).prop("checked",false)
    $("#stay_alert_div").toggle();
  }
});

HttpHeaders是＆＃34; inmutable＆＃34;，其他方法

var headers = new HttpHeaders()
    .set('Content-Type', 'application/json');
    .set('X-Quikr-App-Id', '1087');
    .set('X-Quikr-Token-Id', '785582933');
    .set('X-Quikr-Signature-v2', '86742d91e19bc30cdd923bf6a84194c133570659');
    .set('Access-Control-Allow-Origin', '*');

Answer 2

引用Angular 2 Angular Http Guide @ angular / http已被弃用，@ angular / common / http应该是你在Angular 2 App中使用的那个。因为如果您没有指定http标头，则默认请求将作为Content-Type text / plain发送，如何修改http标头是：

import { HttpClient, HttpHeaders } from '@angular/common/http';  
.....
const req = this.http.get('https://api.quikr.com/public/adsByLocation?lat=28.64649963&lon=77.22570038&from=0&size=1',
                        JSON.stringify(object),
                        {
                         headers:new HttpHeaders()
                         .set('Content-Type','application/json' 
//other headers here
                         }).subscribe();
