I am trying to do put request to the server ,but I am getting 401 error

The provider 

putData(){
header = header.append('Content-Type', 'application/json');
        header = header.append('Accept', 'application/json');
        header = header.append('Authorization', 'Bearer');

      return this.http.put('http://something//', {headers: header})
          .subscribe((result: any) => {
               console.log(result);
          }, (errorResponse) => {
              console.error(errorResponse);

}

home.ts 

this.MyProvider.putData();

I have attach the network header as well since the first request success, but the second does not ?!!!

  • Are you authorized to do a put? See https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401 – Phonolog Oct 07 '18 at 11:41
  • I found what the issue was the header was not being set , now the question how to set it – Nouf Oct 07 '18 at 12:15

import { HttpClient, HttpParams, HttpHeaders} from '@angular/common/http';

  constructor(public http: HttpClient )
putData(){

 const headers = new HttpHeaders({'Authorization':'Basic'});
     return this.http.post("'http://something//'", {headers: headers});
}

i think you code header is not adding properly try this method to add header
