Authorization bearer token Angular 5

I am confused about how to create a good header for a simple Get request in Angular 5.

This is what I need to do in Angular: enter image description here

This is what I have so far:

  getUserList(): Observable<UserList[]> {
    const headers = new Headers();
    let tokenParse = JSON.parse(this.token)             
    headers.append('Authorization', `Bearer ${tokenParse}`);
    const opts = new RequestOptions({ headers: headers });  
    console.log(JSON.stringify(opts));
    const users = this.http.get<UserList[]>(this.mainUrl, opts)
    return users
            .catch(this.handleError.handleError);         
  }

This is the response in my console.log:

{"method":null,"headers":{"Authorization":["Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6ImYwODZlM2FiYTk0ZjVhMjVmNDhiNzlkYmI2YWUwOWY4YzE2MTUyMzg2N2I5MDZiY2MzNWQyNWJiYTZmYTE4YjEwZjA1MjZiNThkZjE2Y2FjIn0.eyJhdWQiOiJmMDExY2M1OC00MGNlLTQzYTktOGY3MS04NDI0OTRlM2E5OTciLCJqdGkiOiJmMDg2ZTNhYmE5NGY1YTI1ZjQ4Yjc5ZGJiNmFlMDlmOGMxNjE1MjM4NjdiOTA2YmNjMzVkMjViYmE2ZmExOGIxMGYwNTI2YjU4ZGYxNmNhYyIsImlhdCI6MTUyMzU1MTQ0NSwibmJmIjoxNTIzNTUxNDQ1LCJleHAiOjE1MjM1NTQ0NDUsInN1YiI6IjIiLCJzY29wZXMiOlsiYXV0aGVudGljYXRlZCIsImFuZ3VkcnUiXX0.E-WdQTl7nPDW0gj0rohfql-QgnAinzvDxPR-pySMrG07XFY9tA6Ex7IL23pDBmKDmQO8RcZKa0L5r6SRQq9_iqzMWzn5Zxp94J9TJrpZ2KGMoLR_FbK_tpC5G5q5vUnCe3q34sH7cPdT_2cI704OWWaYmIUKKpXWUIG0PJw_uKSJ_uOifPv59RZGQkoaQ9gPywDKe-uamm1Faug-Kk2YnFMoEJq7ou19zyxgdpX80ZTPUae67uB0PGLRuvxfGaqVsJ8k0NunAY3-pyUnBwR_3eeuOxf4TyfW2aiOJ9kuPgsfV4Z1JD7nMpNtTHMJaXEyNkBW8RlYHD1pj4dkdnsDmw"]},"body":null,"url":null,"withCredentials":null,"responseType":null}

It looks pretty. But gives me this error

GET http://druang.dd:8080/user-list?_format=json 403 (Forbidden)

There is another clue to solve this mystery. In Sublime text, If I put the mouse over opts it says something like:

ERROR in src/app/services/userlist.service.ts(33,59): error TS2345: Argument of type 'RequestOptions' is not assignable to parameter of type '{ headers?: HttpHeaders | { [header: string]: string | string[]; }; observe?: "body"; params?: Ht...'. Types of property 'headers' are incompatible. Type 'Headers' is not assignable to type 'HttpHeaders | { [header: string]: string | string[]; }'. Type 'Headers' is not assignable to type '{ [header: string]: string | string[]; }'. Index signature is missing in type 'Headers'.

Any idea?? Here is the full Git repo THanks for your help!

I suggest to use HttpInterceptor for setting default HTTP headers on outgoing requests rather than adding an additional HTTP header to each call.

HTTP Client - Setting default headers @ angular.io

In your example you can do the following:

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

getLoggedInUser(auth_token): Observable<any> {
  const headers = new Headers({
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${auth_token}`
  })
  return this.http.get(apiUrl, { headers: headers })
}

For get requests, I used the following code and it works

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

getServerList(){
    var reqHeader = new HttpHeaders({ 
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + JSON.parse(localStorage.getItem('mpManagerToken'))
     });
    return this.http.get<Server[]>(`${environment.apiUrl}/api/Servers/GetServerList`, { headers: reqHeader });
}
