R – In Rails, how can one log the entirety of each incoming HTTP request

I'm building an application that talks to a Rails backend that is POSTing requests to Rails. It's failing. Is there an easy way to have Rails log and spit to console the entirety of each incoming HTTP request?

If anyone is feeling particularly charitable, you may be able to help with the underlying cause. Using a simple curl command works fine:

$ curl -X POST -d "<person><name>Jack</name></person>" -H "Content-Type: application/xml" http://localhost:3000/people.xml
 <?xml version="1.0" encoding="UTF-8"?>
 <person>
  <created-at type="datetime">2009-11-08T16:36:54Z</created-at>
  <id type="integer">3</id>
  <name>Jack</name>
  <updated-at type="datetime">2009-11-08T16:36:54Z</updated-at>
 </person>

But the error Rails spits out when my application sends a request is:
