Curl HTTPS incompatibility - GAE and Facebook ~ Examples

	Part 1 of 3 -- PHP Bug Example, Code Only

(?php
	$ch = curl_init();
	$options = array(CURLOPT_URL => 'https://graph.facebook.com/naitik', 
/** ^ Always generates "cannot be cast" server error. */

	# $options = array(CURLOPT_URL => 'http://graph.facebook.com/naitik',
/** ^ Causes no internal server error but with access_token retrieves:
  *{"error":{"type":"OAuthException","message":"You must use https:\/\/ when passing an access token"}}
  */
		CURLOPT_POSTFIELDS => 'method=GET&access_token=62jf326a.................13jd35',
/** ^ generates above Facebook Oauth error with http urls */

		# CURLOPT_POSTFIELDS => 'method=GET'
/** ^ Generates no Facebook errors, but severely restricts data access. */
	);
	curl_setopt_array($ch, $options);
	curl_exec($ch);
?)
 
 
	Part 2 of 3 -- Alternative Working Java Solution:
(Note: Only requires doNotValidateCertificate() FetchOption with Dev GAE servers.)
 
(?php
	import java.net.URL;
define('URLFetchServiceFactory', new Java('com.google.appengine.api.urlfetch.URLFetchServiceFactory'));
URLFetchServiceFactory->getURLFetchService()->fetch(new URL('https://graph.facebook.com/naitik&method=GET&access_token=62jf326a.................13jd35'))->getContent();
?)
