Actionscript 3: Reading an RSS feed that requires authentication

问题

I have an RSS feed that I need to read, but you need to log in with a valid username and password to get the feed. I was wondering if or how to do this using Actionscript 3.

Right now I have a very simple script that just gets the xml from a provided url and outputs the xml to the console.

I've verified that it works with a feed that doesn't require authentication.

Let me know if code or anything more specific is needed.

Thanks in advance!

If you're using an http service, you can do basic authorization with by extending the HTTPService :

package{
    import mx.rpc.AsyncToken;
    import mx.rpc.http.mxml.HTTPService;
    import mx.utils.Base64Encoder;

    public class HTTPServiceAuth extends HTTPService
    {
        public var username : String = '';
        public var password : String = '';
        public function HTTPServiceAuth(rootURL:String=null, destination:String=null)
        {
            super(rootURL, destination);
        }

        override public function send(parameters:Object=null ):AsyncToken {
            var enc : Base64Encoder = new Base64Encoder();
            enc.insertNewLines = false;
            enc.encode(username + ':' + password );
            this.headers = {Authorization:"Basic " + enc.toString())};
            super.send(parameters);
        }
    }
}

You use it the same way except you can specify a username and password :

<local:HTTPServiceAuth url="http://www.domain.com/feed/etc" username="myUsername" password="myPassword" ...rest of standard args, etc... />
