How to get parameter value from query string?
<p>How can I define a route in my routes.jsx file to capture the <code>__firebase_request_key</code> parameter value from a URL generated by Twitter's single sign on process after the redirect from their servers?</p>

<pre><code>http://localhost:8000/#/signin?_k=v9ifuf&amp;__firebase_request_key=blablabla
</code></pre>

<p>I tried with the following routes configuration, but the <code>:redirectParam</code> is not catching the mentioned param:</p>

<pre><code>&lt;Router&gt;
  &lt;Route path="/" component={Main}&gt;
    &lt;Route path="signin" component={SignIn}&gt;
      &lt;Route path=":redirectParam" component={TwitterSsoButton} /&gt;
    &lt;/Route&gt;
  &lt;/Route&gt;
&lt;/Router&gt;
</code></pre>
