CORS problems with @ionic-native/http/ngx

I’m new to ionic, (I’m training from 1 week). I would like to develop an RSS parser app running both on browser and on devices (iOS and Android). I’m using ionic4 angular7.
Due to CORS error I’m using @ionic-native/http/ngx as suggested in this post.
I added browser “device” to my app and I run:

# ionic cordova run browser

The code is very simple, in home.module.ts:

import { HTTP } from '@ionic-native/http/ngx';
...
 constructor(private http: HTTP) {
  }
...
ionViewWillEnter() {
    this.http.get(this.url, {}, {})
        .then(data => {
          console.log(data.status);
          console.log(data.data);
          console.log(data.headers);
        })
        .catch(error => {
          console.log(error.status);
          console.log(error.error); // error message as string
          console.log(error.headers);
        });
  }

And the error is:

Access to XMLHttpRequest at '...the url...' from origin 'http://localhost:8000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

What is the way to bypass CORS error also with browser?
