AS3 - Sending POST data to another domain without loading (Sandbox security)

问题

I need to send POST Data to a ASP script on a different domain name ( without loading data).

var scriptRequest :URLRequest = new URLRequest( 'http://someExternalCart.com/cart.asp' );
scriptRequest.method = URLRequestMethod.POST;
scriptRequest.data = scriptVars;

It works with navigateToUrl, BUT I don't want to get redirected to that page, I only want to send the data.

I have tried this:

var ldr :URLLoader = new URLLoader();
ldr.load( scriptRequest );

But I am getting the sandbox security error.

Is there any other way of sending the data without redirection/page reload and without loading (which causes the security error)?

回答1:

If you don't have access to the server to add the crossdomain.xml security policy file, you will need to set up a proxy on your own server that passes the request through for you (something like http://xmlrpcflash.mattism.com/proxy_info.php).

To avoid sandbox error, you need a crossdomain file on "http://someExternalCart.com/".

Or you can use a script (php, asp...) on your webserver that will act as a proxy.
