Can't retrieve files from request object

Hi there - I have a very small application that works as follows:

1.  I send an email to mailgun

2.  Mailgun parses the message and POST it to my web page/controller over HTTP

3.  My application has a single controller (no models or views) with one method that currently only does this:

$this->log($this->request->data);

4.  Here is some additional information on the attachment fields from mailgun when the POST to my service.

attachment-x

string

attached file ('x' stands for number of the attachment). Attachments are handled as file uploads, encoded as multipart/form-data.

content-id-map

string

JSON-encoded dictionary which maps Content-ID (CID) of each attachment to the corresponding attachment-x parameter. This allows you to map posted attachments to tags like <img src='cid'> in the message body.

Anyhow, the issue is that I can't seem to figure out how to retrieve the attachment-1, nor can I see it in  the response.   

Here is a dump of my request object received when a new message is received.  Note that the [content-id-map] and [attachment-count] are both there.   The [attachment-1] is also referenced in the [content-id-map]

*******

    [recipient] => testreceiver@ducksoup.mailgun.org

    [sender] => mday@gmail.com

    [body-plain] => > BODY OF MESSAGE.    MESSAGE SHOULD HAVE 1 ATTACHMENT

   [stripped-text] => > BODY OF MESSAGE.    MESSAGE SHOULD HAVE 1 ATTACHMENT

    [content-id-map] => {"<99098F-9DD-44A9-AC75-B652BA@vlan1.phub.net.cable.rogers.com>": "attachment-1"}
