title: Path variables in Angular 2
body: <pre><code>@RouteConfig([
    { path: '/post/:post_id', component: PostComponent }
  ])
  </code></pre>
  
  <p>Using this classic route strategy <code>/post/1715</code> I received this JSON data. </p>
  
  <pre><code>{
    "post_id": 1715,
    "title": "The Post Title",
    "urlTitle": "the-post-title",
    "body": "Blah, blah ... blah"
  }
  </code></pre>
  
  <p>But how to redirect router to Stackoverflow URL style <code>/post/1715/the-post-title</code> by adding <code>urlTitle</code> to the link?</p>
