title: how do I print a Rails POST request output?
body: <p>I have this request:</p>
  <pre><code>post '/api/v1/fruit', params: valid_fruits, headers: lots_of_security
  </code></pre>
  <p>how can I see what's going on behind the scenes and see the many fruits contained in the <code>raw output</code> that will be sent after executing it?</p>
