No provider for Http! error in ionic

Ionic Framework ionic-v3

Gracias @joshmorony call from Agentina!

I saw many people complaining about append would not be working correctly on headers. Try the following:

const headers = new Headers({
  'Accept': 'application/json',
  'Content-Type': 'application/json',
  'Access-Control-Allow-Origin': '*'
});

What is wrong in this code?

    const headers = new Headers({
      'Accept': 'application/json',
      'Content-Type': 'application/json',
      'Access-Control-Allow-Origin': '*',
      'Authorization': this.token
    });


    this.api.get("users", {headers: headers}).subscribe((users: any) => {
      this.users = users;
 
    })

Please, help me!
