问如何在聚合物启动器试剂盒中设置baseUrl？

EN

// Sets app default base URL
  app.baseUrl = '/';

  if (window.location.port === '') {  // if production
    // Uncomment app.baseURL below and
    // set app.baseURL to '/your-pathname/' if running from folder in production
    // app.baseUrl = '/polymer-starter-kit/';


   // If this is baseURL:
   //app.baseUrl = 'http://localhost/test/psk/app/';
   //Then click on the menu -  reloads the page with 404 URL:
   //http://localhost/test/psk/app/users
  }
