How to read a jpg bytearray from a Flash AS3 file

[rsgalloway at gmail.com]

I'm trying to save an image from a Flash AS3 to my server as a jpg
file. I found some PHP code to do this, but I want to do this in
Python. I'm not quite sure how to convert the following code to
Python. It's mainly the $GLOBALS["HTTP_RAW_POST_DATA"] part I don't
know how to convert.

<?php

if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {

	// get bytearray
	$im = $GLOBALS["HTTP_RAW_POST_DATA"];

	// save image
	$f = fopen($_GET['name'], 'wb');
	fwrite($f, $jpg);
	fclose($f);

}  else echo 'An error occured.';

?>
