本文详细介绍了Flash中LocalConnection的使用方法，包括网络与本地之间的发送与接收过程。重点讲解了如何在一个connectionName下实现一个接收端对应多个发送端的情况，并讨论了不同域名下通信的配置。

1.网络与本地的localConnection,网络send，本地get:

a.本地接收端

var conn:LocalConnection = new LocalConnection(); conn.allowDomain('www.2.com'); conn.client = this; try { conn.connect("myConnection"); } catch (error:ArgumentError) { out_txt.appendText("Can't connect...the connection name is already being used by another SWF"); } function lcHandler(msg:String,msg2:String):void { out_txt.appendText("new msg:"+msg+' '+msg2 + "/n"); }

b.网络发送端

var conn:LocalConnection = new LocalConnection(); conn.addEventListener(StatusEvent.STATUS, onStatus); function onStatus(event:StatusEvent):void { switch (event.level) { case "status" : out_txt.appendText("LocalConnection.send() succeeded/n"); break; case "error" : out_txt.appendText("LocalConnection.send() failed/n"); break; } } sendBtn.addEventListener(MouseEvent.CLICK, sendMessage); function sendMessage(event:MouseEvent):void { conn.send("localhost:myConnection","lcHandler",conn.domain,"I send it"); }

2.网络get，本地send

a.网络接收端

var conn:LocalConnection = new LocalConnection(); conn.allowInsecureDomain('localhost'); conn.client = this; try { conn.connect("myConnection"); } catch (error:ArgumentError) { out_txt.appendText("Can't connect...the connection name is already being used by another SWF"); } function lcHandler(msg:String,msg2:String):void { out_txt.appendText("new msg:"+msg+' '+msg2 + "/n"); }

b.本地发送端

var conn:LocalConnection = new LocalConnection(); conn.addEventListener(StatusEvent.STATUS, onStatus); function onStatus(event:StatusEvent):void { switch (event.level) { case "status" : out_txt.appendText("LocalConnection.send() succeeded/n"); break; case "error" : out_txt.appendText("LocalConnection.send() failed/n"); break; } } sendBtn.addEventListener(MouseEvent.CLICK, sendMessage); function sendMessage(event:MouseEvent):void { conn.send("2.com:myConnection","lcHandler",conn.domain,"I send it"); }

这里注意发送过去的域的写法，如果接受方的swf处于www.2.com/temp/test/get.swf 则要设定域为2.com:

LocalConnection可以实现在同一个connectionName的情况下1个get多个send，但是实现不了1个send多个get。如果是多个connectionName可以单独发送从而实现1个send多个get
