Angular2 HTTP Post请求到FCM服务器不工作

Question

使用Ionic 2和angular http我试图向https://fcm.googleapis.com/fcm/send发出http post请求，用postman测试的请求工作得非常好

这个问题是我这个问题的后续问题：

http请求的代码是

import { Http, Headers } from '@angular/http';

......

constructor(public http: Http) { }

sendPushNotification(deviceId: string) {
  let url = 'https://fcm.googleapis.com/fcm/send';
  let body = 
   {
     "notification": {
         "title": "Notification title",
         "body": "Notification body",
         "sound": "default",
         "click_action": "FCM_PLUGIN_ACTIVITY",
         "icon": "fcm_push_icon"
     },
     "data": {
         "hello": "This is a Firebase Cloud Messagin  hbhj g Device Gr new v Message!",
     },
     "to": "device token"
   };

  let headers: Headers = new Headers();
  headers.append('content-type', 'application/json');
  headers.append('Authorization', 'key='+someKey);

  this.http.post(url, body, headers).map(response => {
    return response;
  }).subscribe(data => {
     //post doesn't fire if it doesn't get subscribed to
     console.log(data);
  });
}

来自chrome控制台的标题如下：

Answer 1

通过将头添加为requestoptions来实现这一点，

let headers: Headers = new Headers({
  'Content-Type': 'application/json',
  'Authorization': 'key='+this.someKey
});
let options = new RequestOptions({ headers: headers });
