Sockets con php y actionscript, no conecta http://www.kirupa.com/developer/flas...ets_flash8.htm
Donde creamos un script php que hace de servidor y un chat en actionscript que se comunica con este a traves de sockets.
codigo flash (el que no se conecta, AS2):
Código:
Shell script php (servidor, va bien):mySocket = new XMLSocket();
mySocket.onConnect = function(success) {
if (success) {
msgArea.htmlText += "<b>Server connection established!</b>";
} else {
msgArea.htmlText += "<b>Server connection failed!</b>";
}
};
mySocket.onClose = function() {
msgArea.htmlText += "<b>Server connection lost</b>";
};
XMLSocket.prototype.onData = function(msg) {
msgArea.htmlText += msg;
};
mySocket.connect("192.168.1.104", 9999);
//--- Handle button click --------------------------------------
function msgGO() {
if (inputMsg.htmlText != "") {
mySocket.send(inputMsg.htmlText+"\n");
inputMsg.htmlText = "";
}
}
pushMsg.onRelease = function() {
msgGO();
};
Código PHP:
#!/usr/bin/php -q

// socket_create function is pretty simple, depending on what you want it to do, you can just rig it for that,

// then socket_create takes and uses SOCK_STREAM, another default available socket type,
// and uses a SOL_TCP protocol to have a guaranteed data sending.

// we want to be able to reuse our sockets, so we set our $master socket with a level at SOL_SOCKET,
// with it reusable (SO_REUSEADDR), and a "1" in the mixed optval spot to make it true.
socket_set_option($master, SOL_SOCKET,SO_REUSEADDR, 1);
// now we need to bind our socket to the address and port specified.
if (($ret = socket_bind($master, $address, $port)) < 0) {

// to allow our socket server to listen for incoming calls made by our flash client, we need
// to use socket_listen on our $master socket. The next flag indicates that only 5 calls at a time.
// any others will be refused until there is sufficient room to process a new call.

?> Pero cuando flash intenta conectarse al servidor, no lo consige, y eso que he indicado la misma direccion ip y puertos en ambos.
He estado leyendo y creo que tiene que ver con la politica de sockets de adobe, he creado un archivo crossdomain.xml con el siguiente contenido:
Código:
Y lo he puesto en el directorio del proyecto, pero nada..<?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd"> <!-- Policy file for xmlsocket://socks.example.com --> <cross-domain-policy> <!-- This is a master socket policy file --> <!-- No other socket policies on the host will be permitted --> <site-control permitted-cross-domain-policies="master-only"/> <!-- Instead of setting to-ports="*", administrator's can use ranges and commas --> <!-- This will allow access to ports 123, 456, 457 and 458 --> <allow-access-from domain="*" to-ports="*" /> </cross-domain-policy>
Todos los archivos estan en una carpeta en mi servidor wamp, ¿Como lo arreglo?
Gracias!
