title: Make GET call to REST service with parameters in Angular 2
body: <p>I am trying to make a GET call to the YouTube Web API but I cannot figure out how to pass parameters using the http.get function. I have used fiddler and made sure the request is being made. I am currently getting a 400 error saying that I am missing a the parameter "Part". How can I modify my code to include the required parameters in my request?</p>
  
  <pre><code>private _url = 'https://www.googleapis.com/youtube/v3/';
  private _key = '';
  
  getPlaylistVideos(playlistId, pageToken){
  
      var url = this._url + "playlistItems";
      var options =  { part: 'snippet', maxResults: 50, playlistId: playlistId, key: this._key, pageToken: pageToken }
  
      return this.http.get(url, options);
  
  }
  </code></pre>
