title: Angular HttpClient params with method GET do not work
body: <p>I wanna ask you about params with get method.
  I have something like this:</p>
  
  <pre><code>    path = 'https://example.com/api';
      const params = new HttpParams();
      params.append('http', 'angular');
      return this.http.get(path, {params: params});
  </code></pre>
  
  <p>I thought I would have url like:</p>
  
  <blockquote>
    <p>www.example.com/api?http=angular</p>
  </blockquote>
  
  <p>but actually when I check that in network tab in chrome, request url is </p>
  
  <blockquote>
    <p>www.example.com/api</p>
  </blockquote>
  
  <p>What should I do when I want to have path: www.example.com/api?http=angular
  And is it possible to check request url of used method without chrome? I mean in service where I use that method?</p>
