Angular 4.3. Sent httpclient response headers

I have a Django backend. And trying to get http headers from it, using: 1) Angular 4.3 Http (it will become obsolete) 2) Normal XmlHttprequest. 3) Angular 4.3 HttpClient

1) and 2) have headers. But 3) does not.

Headings from 1):

var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { console.log(this); console.log(xhttp.getAllResponseHeaders()); } }; xhttp.open("GET", "http://127.0.0.1:8000/csbg/survey/sometest/", true); xhttp.send();

Headers from 2):

 import { HttpModule} from '@angular/http'; this.http.get('http://127.0.0.1:8000/csbg/survey/sometest/') .subscribe( data=>{ console.log('GET OK') console.log(data) }, error=>{ console.log("GET ERROR: " + error); } )

Headings from (2)

Headings from 3):

 import { HttpClient} from '@angular/common/http' this.http.get('http://127.0.0.1:8000/csbg/survey/sometest/', { observe: 'response' }) .subscribe( data=>{ console.log('GET OK') console.log(data) }, error=>{ console.log("GET ERROR: " + error); } )
