Localhost GET request doesn't work on Angular

Question

I have this code:

  login: any;

  constructor(private http: HttpClient) { }

  ngOnInit() {
    this.http.get("http://localhost:8000/login/list")
      .subscribe(
        resultado => {
          this.login = resultado;
          document.write(this.login);
        }
      );
  }

I tried to get data from a JSON located on the web and I got the data, However. when I try to get it from the localhost server (which is running a PHP application and returning JSON) it doesn't seems to work. I tried to open the URL on the web browser and it does actually return a JSON.

Any clue on what's going on?

Problem was CORS.

Adding this to my PHP project made it work:

composer req cors --ignore-platform-req=ext-http
