How to rewrite jquery code in angular2?

Question

JavaScript

Hello.
I need to rewrite the request code from jquery to angular2.
There is a code:

$.get("https://ipinfo.io", function(response) {
  console.log(response.ip, response.country);
}, "jsonp")

I rewrote it like this:

public getLocationUser() {
    let headers = new Headers({ 'Content-Type': 'application/json'}); //../jsonp
    let options = new RequerstOptions({ headers: headers })
    return this.http.get("https://ipinfo.io", options).map(location => location.json())
      .subscribe((loc) => loc)
  }

Through jquery data comes in json format!
And through the getLocationUser() method - as text!
How to fix it ?!
