否, 在不使用任何外部部分( PHP、 MySQL、 Java 等...) 的情况下, 只能使用 Flash 来操作, 并不容易。 记住 Flash 是本地运行的, 因此需要与 PHP 或类似服务器进行互动, 以便与服务器进行互动, 告诉服务器用户的活动, 并向服务器询问其他用户的活动( 在线用户数量 ) 。

如果您只想在网上显示用户, 我建议您张贴的示例中显示的方式 。 只需在用户看到活动时更新数据库, 并在X分钟内未看到活动时将用户计为离线 。 没有必要为此使用 XMLSocket, 除非您希望用户以任何方式互动 。

如果您想要的不仅仅是在网上显示用户, 我建议在 ActionScript 中使用 XMLS 套件, 并查看 PHP Sockets 。

最简单的办法是将 URLRequest (我希望我得到类名正确) 发送到服务器脚本, 可以是 php 或 asspx (或任何服务器技术) 脚本/ 页面 。

服务器脚本应该返回网站的用户数量 。

例如:

var numberOfVisitors:Int = 0;

function onLoaded(e:Event):void {
    numberOfVisitors = e.target.data;

    // now print this  numberOfVisitors  where you want to on the client
}

var numVisitors:URLLoader = new URLLoader();
numVisitors.addEventListener(Event.COMPLETE, onLoaded);
numVisitors.load(new URLRequest("num_users.php"));

下一部分将是一个 php 脚本( 或任何其他服务器脚本), 记录用户数量 。 我认为您应该作为另一个 SO 问题发布?

我得到了它的工作, 但我很乐于连接 php 文件, 而不是通过它 HTTP 地址, 而是连接. swf 文件的路径( 仅是我的File.php 或路径/ MyFile.php ) 。

AS3 file:

NewRequest = new URLRequest("numOnline.php");
var numberOfVisitors:int = 10;
var NewRequest:URLRequest;
var UrlLoader:URLLoader;

UrlLoader = new URLLoader();
UrlLoader.dataFormat = URLLoaderDataFormat.TEXT;
UrlLoader.addEventListener(Event.COMPLETE, onLoaded);
UrlLoader.load(NewRequest);


function onLoaded(e:Event):void {
    trace(e.target.data);
    numberOfVisitors = int(e.target.data);
}

我将As3收到的文本转换为Int, 因为我还不知道如何发送 veria

"http://www.shaddeen.com/posts/read/ id- 1326397267" rel="nofollow">php文件

main PHP file (the file that as3 connects to):

<?php
include_once  config.php ; //This file would contain the variables needed to connect to the database with $link, below
include_once  functions.php ; //We include the functions we have created

$database = "online";

$link = mysql_connect($server, $db_user, $db_pass)or die ("Could not connect to mysql because ".mysql_error());
mysql_select_db($database)or die ("Could not select database because ".mysql_error());

usersOnline(5); //We call the usersOnline function with a time span of 5 minutes

showUsersOnline(1); //Show the number of users online, and the list of users

mysql_close($link);

?>

函数文件以 ecececho $count; 发送在线访问者的数量

Yes, you can do it without a database (MYSQL) and PHP; BUT you will still need a (Media) Server. I wouldn t suggest the following if your "only" purpose is to count the connecting clients, but if you have the reasons and have access to a Flash Media Server, you can try the following:

<强> 服务器侧:

1. Create an application (folder) on FMS, create the main.asc file inside that folder.
2. Inside the main.asc; create a (remote) SharedObject (server-side) (e.g.: users_so)
3. Watch for connecting clients on application.onConnect event. Add each connecting client to that SharedObject inside this handler.
4. Also watch for disconnecting clients on application.onDisconnect event. Remove each disconnecting client from the SharedObject inside this handler.

<强 > 客户端 :

1. Connect each Flash client to FMS (with your new app-folder path in the URI) when the application loads in the browser.
2. Watch for the NetStatusEvent.NET_STATUS event and "NetConnection.Connect.Success" code. When connected; create a SharedObject (client-side) and get the remote from the server.
3. Add the SyncEvent.SYNC event listener to the SharedObject. This will sync with each Flash client when a user connects or disconnects from the server.
4. Inside the sync event handler, get and count the users from the event response.
5. Display the count on your Flash client.

See Server-Side ActionScript Language Reference for Flash Media Server 4.5, especially the Application Class. Also useful: Flash Media Server Developer Center
