We took on a small task today to add our latest Tweet's to the homepage of our site. We decided to go with the library twitterscript. It's a nice simple wrapper around the twitter API and allows you to quickly create your app. All this with one catch. Out of the box it only works locally due to twitters cross domain policy.

To get around this we had to make a few tweaks to the code and add a proxy file.

Twitter.as - Changed lines 55 - 98

PLAIN TEXT

  43.         private static const FOLLOWERS_IDS_URL:String =

Then adding a proxy.php file to our server:

PLAIN TEXT
Actionscript:
  1. <?php
  2. // PHP Proxy
  3. //for higher security just put the url you want here or build
  4. //your url with GET or POST parameters. Not the best idea to
  5. //pass the entire url
  6.  
  7. //make sure we're using http
  8. $url = 'http://';
  9. if (isset($_GET['sd']) && $_GET['sd'] != '')
  10. {
  11.     $url .= $_GET['sd'].'.';
  12. }
  13. //ensure only twitter domains are used
  14. $url .= 'twitter.com/';
  15.  
  16. if (isset($_GET['path']) && $_GET['path'] != '')
  17. {
  18.     $url .= $_GET['path'];
  19. }
  20. //you can change this to set mimeType via parameters, but
  21. //chances are you want xml
  22. $mimeType = 'application/xml';
  23.  
  24. $response = file_get_contents($url);
  25.  
  26. if ($mimeType != "")
  27. {
  28.     header("Content-Type: ".$mimeType);
  29. }
  30.  
  31. echo $response;
  32.  
  33.  
  34. ?>

Do this and you'll be rid of the Security Errors and able to integrate Twitter into your Flash site.
