我想通过 HTTP 请求使用在线 Mysql 数据库、Scaleform 4 (AS3) 和 PHP 向我的网络服务器发布并获取我的 UDKGame 的高分。不幸的是，我认为这可能是不可能的，考虑到这个文件： http: //gameware.autodesk.com/documents/gfx_4.0_flash_support.pdf。

我尝试从我的 GFx 电影播放器​​发送 URLRequest，但它似乎不起作用。这是我在第 1 帧中用于 GFx 电影播放器​​的 AS3 代码：

getScore();

function getScore():void {
//var url:String = "http://myserver.com/getScore.php";
    var request:URLRequest = new URLRequest(url);
    var requestVars:URLVariables = new URLVariables();
    requestVars.foo = "bar";
    request.data = requestVars;
    //request.method = URLRequestMethod.POST;
    //Security.allowDomain("myserver.com"); 
    //var context:LoaderContext = new LoaderContext();
    //context.securityDomain = SecurityDomain.currentDomain

    var urlLoader:URLLoader = new URLLoader();
    urlLoader = new URLLoader();
    urlLoader.dataFormat = URLLoaderDataFormat.TEXT;
    urlLoader.addEventListener(Event.COMPLETE, loaderCompleteHandler, false, 0, true);
    urlLoader.load(request);

    }

function loaderCompleteHandler(e:Event):void {
    trace(e.target.data);
    Object(this).response.text= "response:"+e.target.data;

}

有什么方法可以在不编写 .dll 或使用手动 TCP 连接到我的网络服务器的情况下实现我的目标？

不幸的是，UDK (4.0.16) 附带的 Scaleform 没有内置任何网络支持。您必须让 UDK 通过 dll 绑定或其他方式解决该问题。Scaleform 4.2 添加了网络支持，但该版本的 Scaleform 尚未完全集成到 UDK 中。不过，它正在整合过程中，所以希望我们很快就能看到它。

确实 SF4.0 不支持这一点。SF4.2可能会，而且它只对 UE3 被许可人提供，通过 Epic 的 Perforce 库。

你可以在虚幻脚本中做到这一点。然而，使用 dll 或 TCP 连接有点矫枉过正。使用HttpRequestInterface。这是一个直接来自随 UDK 提供的源示例的示例。它非常简单，您可以将其缩减到只用几行代码调用您的 Web 服务所必需的严格要求。

/**
 * Simple function to illustrate the use of the HttpRequest system.
 */
exec function TestHttp(string Verb, string Payload, string URL, optional bool bSendParallelRequest)
{
    local HttpRequestInterface R;

    // create the request instance using the factory (which handles
    // determining the proper type to create based on config).
    R = class'HttpFactory'.static.CreateRequest();
    // always set a delegate instance to handle the response.
    R.OnProcessRequestComplete = OnRequestComplete;
    `log("Created request");
    // you can make many requests from one request object.
    R.SetURL(URL);
    // Default verb is GET
    if (Len(Verb) > 0)
    {
        R.SetVerb(Verb);
    }
    else
    {
        `log("No Verb given, using the defaults.");
    }
    // Default Payload is empty
    if (Len(Payload) > 0)
    {
        R.SetContentAsString(Payload);
    }
    else
    {
        `log("No payload given.");
    }
    `log("Creating request for URL:"@URL);

    // there is currently no way to distinguish keys that are empty from keys that aren't there.
    `log("Key1 ="@R.GetURLParameter("Key1"));
    `log("Key2 ="@R.GetURLParameter("Key2"));
    `log("Key3NoValue ="@R.GetURLParameter("Key3NoValue"));
    `log("NonexistentKey ="@R.GetURLParameter("NonexistentKey"));
    // A header will not necessarily be present if you don't set one. Platform implementations
    // may add things like Content-Length when you send the request, but won't necessarily
    // be available in the Header.
    `log("NonExistentHeader ="@R.GetHeader("NonExistentHeader"));
    `log("CustomHeaderName ="@R.GetHeader("CustomHeaderName"));
    `log("ContentType ="@R.GetContentType());
    `log("ContentLength ="@R.GetContentLength());
    `log("URL ="@R.GetURL());
    `log("Verb ="@R.GetVerb());

    // multiple ProcessRequest calls can be made from the same instance if desired.
    if (!R.ProcessRequest())
    {
        `log("ProcessRequest failed. Unsuppress DevHttpRequest to see more details.");
    }
    else
    {
        `log("Request sent");
    }
    // send off a parallel request for testing.
    if (bSendParallelRequest)
    {
        if (!class'HttpFactory'.static.CreateRequest()
            .SetURL("http://www.epicgames.com")
            .SetVerb("GET")
            .SetHeader("Test", "Value")
            .SetProcessRequestCompleteDelegate(OnRequestComplete)
            .ProcessRequest())
        {
            `log("ProcessRequest for parallel request failed. Unsuppress DevHttpRequest to see more details.");
        }
        else
