title: Accessing request body with ZombieJS
body: <p>I'm using ZombieJS v4 (4.0.13), and am trying to access the client's request body, since some tests require me to monitor the fields that are automatically sent via client forms.
  While I can access all the query-string fields by using the pipeline's addHandler hook, I can't seem to read the request body in order to extract body post params.</p>
  
  <p>Working with the <strong>response</strong> body is easy - I can access it from the pipeline by waiting for the response to consume. But the request body always appears as null, with <em>_bodyUsed = true</em>, so I can't wait for it in the same manner.</p>
  
  <p>Anyone knows of a way I can access the sent request body, either via the pipeline, or somewhere else?</p>
