Http Client in ActionScript

Here’s the translation of the HTTP Client example from Go to ActionScript:

Our example demonstrates how to create a simple HTTP client in ActionScript. We’ll use the URLLoader class to issue HTTP requests.

package {
    import flash.net.URLLoader;
    import flash.net.URLRequest;
    import flash.events.Event;
    import flash.events.IOErrorEvent;

    public class HTTPClient extends Sprite {
        public function HTTPClient() {
            var loader:URLLoader = new URLLoader();
            var request:URLRequest = new URLRequest("https://example.com");

            loader.addEventListener(Event.COMPLETE, onComplete);
            loader.addEventListener(IOErrorEvent.IO_ERROR, onError);

            try {
                loader.load(request);
            } catch (error:Error) {
                trace("Error occurred: " + error.message);
            }
        }

        private function onComplete(event:Event):void {
            var loader:URLLoader = URLLoader(event.target);
            
            trace("Response received");
            
            // Print the first 5 lines of the response
            var lines:Array = loader.data.split("\n");
            for (var i:int = 0; i < Math.min(5, lines.length); i++) {
                trace(lines[i]);
            }
        }

        private function onError(event:IOErrorEvent):void {
            trace("Error loading URL: " + event.text);
        }
    }
}

In this example, we’re using the URLLoader class to send an HTTP GET request to a server. Here’s a breakdown of what’s happening:

1. We create a new URLLoader instance and a URLRequest object with the URL we want to request.

2. We add event listeners for the COMPLETE and IO_ERROR events. These will handle successful responses and errors respectively.

3. We use the load method of URLLoader to send the request. This is wrapped in a try-catch block to handle any immediate errors.

4. In the onComplete function, we handle the response. We print a status message and then the first 5 lines of the response body.

5. If an error occurs, it’s handled in the onError function.

Note that ActionScript doesn’t have built-in support for printing HTTP status codes like Go does. To get such information, you would need to use the more complex URLStream class instead of URLLoader.

To run this code, you would typically compile it into a SWF file and run it in a Flash environment or AIR application. The exact process depends on your development setup and target platform.

Remember that ActionScript is typically used in the context of Flash applications, so the execution environment and output methods may differ from command-line programs in languages like Go.
