If you need to submit data at the time of network request, you need to use URLVariables.

With the URLVariables class, variables can be transferred between the application and the server. Use the URLVariables object, together with the URLLoader class method, the data attribute of the URLRequest class.

In general, submitting data to the server actually contains two steps, namely, submitting data and reading the returned information.

1. The submitted data is placed in the data attribute value of the URLRequest object and submitted via the URLRequest object.

2. Read the data returned by the server-side script.

The specific sample code is as follows:

class NetDemo extends egret.DisplayObjectContainer
{
    public constructor()
    {
        super();
        this.addEventListener(egret.Event.ADDED_TO_STAGE,this.onAddToStage,this);
    }
    private onAddToStage(event:egret.Event)
    {
        var url:string = "http://httpbin.org/post";
        var loader:egret.URLLoader = new egret.URLLoader();
        loader.addEventListener(egret.Event.COMPLETE, this.onPostComplete, this);
        var request:egret.URLRequest = new egret.URLRequest(url);
        request.method = egret.URLRequestMethod.POST;
        request.data = new egret.URLVariables("test=ok");
        loader.load(request);
    }
    private onPostComplete(event:egret.Event):void
    {
        var loader:egret.URLLoader = <egret.URLLoader> event.target;
        var data:egret.URLVariables = loader.data;
        console.log( data.toString() );
    }
}

Run after compilation, with the effect shown as below:
