How to correctly set Http Request Header in Angular 2

by

Your parameter for the request options in http.put() should actually be of type RequestOptions. Try something like this:

let headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('authentication', `${student.token}`);

let options = new RequestOptions({ headers: headers });
return this.http
    .put(url, JSON.stringify(student), options)
