いくつかの WebSocket をテストしていますが、いくつかのトリガー/イベントの作成に問題があります。
これが可能かどうかはまったくわかりませんが、試してみたいだけです。
だから私は例をダウンロードしました、そして私は現在それをいじっているだけです
server.php は次のようになります。
<?php
include("C:\wamp\www\social\index.php");
// prevent the server from timing out
set_time_limit(0);
// include the web sockets server script (the server is started at the far bottom of this file)
require 'class.PHPWebSocket.php';
// when a client sends data to the server
function wsOnMessage($clientID, $message, $messageLength, $binary) {
global $Server;
$Server->log('received message from ' . $Server->wsClients[$clientID]['user']);
$ip = long2ip( $Server->wsClients[$clientID][6] );
// check if message length is 0
if ($messageLength == 0) {
$Server->wsClose($clientID);
return;
}
//The speaker is the only person in the room. Don't let them feel lonely.
if ( sizeof($Server->wsClients) == 1 ){
$item = wire('pages')->get('template=item');
$Server->wsSend($clientID, "There isn't anyone else in the room, but I'll still listen to you. --Your Trusty Server");
$Server->wsSend($clientID, $clientID);
}
else
//Send the message to everyone but the person who said it
foreach ( $Server->wsClients as $id => $client )
if ( $id != $clientID ){
$Server->wsSend($id, "Visitor $clientID ($ip) said \"$message\" ");
}
}
// when a client connects
function wsOnOpen($clientID)
{
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );
$Server->wsClients[$clientID]['user'] = wire('user')->name;
$Server->log( "$ip ($clientID) has connected. Username: " . $Server- >wsClients[$clientID]['user'] );
//Send a join notice to everyone but the person who joined
foreach ( $Server->wsClients as $id => $client )
if ( $id != $clientID ){
$Server->wsSend($id, "Visitor $clientID ($ip) has joined the room.");
}
}
// when a client closes or lost connection
function wsOnClose($clientID, $status) {
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );
$Server->log( "$ip ($clientID) has disconnected." );
//Send a user left notice to everyone in the room
foreach ( $Server->wsClients as $id => $client )
$Server->wsSend($id, "Visitor $clientID ($ip) has left the room.");
}
function wsOnTest($clientID, $status) {
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );
$Server->log("Custom message");
//Send a user left notice to everyone in the room
foreach ( $Server->wsClients as $id => $client )
$Server->wsSend($id, "Custom message");
}
// start the server
$Server = new PHPWebSocket();
$Server->bind('message', 'wsOnMessage');
$Server->bind('open', 'wsOnOpen');
$Server->bind('close', 'wsOnClose');
$Server->bind('test', 'wsOnTest');
// for other computers to connect, you will probably need to change this to your LAN IP or external IP,
// alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME']))
$Server->wsStartServer('127.0.0.1', 9300);
?>
そして、これは単純なチャット アプリケーションを含む index.html です。server.php とこのファイルの両方でわかるように、イベントまたは test と呼ばれる関数を作成してだまそうとしました。
<!doctype html>
<html>
<head>
<meta charset='UTF-8' />
<style>
input, textarea {border:1px solid #CCC;margin:0px;padding:0px}
#body {max-width:800px;margin:auto}
#log {width:100%;height:400px}
#message {width:100%;line-height:20px}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="fancywebsocket.js"></script>
<script>
var Server;
function log( text ) {
$log = $('#log');
//Add text to log
$log.append(($log.val()?"\n":'')+text);
//Autoscroll
$log[0].scrollTop = $log[0].scrollHeight - $log[0].clientHeight;
}
function send( text ) {
Server.send( 'message', text );
}
function test( text ){
Server.send('test', text);
}
$(document).ready(function() {
log('Connecting...');
Server = new FancyWebSocket('ws://127.0.0.1:9300');
$('#message').keypress(function(e) {
if ( e.keyCode == 13 && this.value ) {
log( 'You: ' + this.value );
send( this.value );
test( this. value);
$(this).val('');
}
});
//Let the user know we're connected
Server.bind('open', function() {
log( "Connected." );
});
//OH NOES! Disconnection occurred.
Server.bind('close', function( data ) {
log( "Disconnected." );
});
//Log any messages sent from server
Server.bind('message', function( payload ) {
log( payload );
});
Server.bind('test', function( payload ) {
log( payload );
});
Server.connect();
});
</script>
</head>
<body>
<div id='body'>
<textarea id='log' name='log' readonly='readonly'></textarea><br/>
<input type='text' id='message' name='message' />
</div>
</body>
</html>
そして最後に、fancywebsocket.js
var FancyWebSocket = function(url)
{
var callbacks = {};
var ws_url = url;
var conn;
this.bind = function(event_name, callback){
callbacks[event_name] = callbacks[event_name] || [];
callbacks[event_name].push(callback);
return this;// chainable
};
this.send = function(event_name, event_data){
this.conn.send( event_data );
return this;
};
this.connect = function() {
if ( typeof(MozWebSocket) == 'function' )
this.conn = new MozWebSocket(url);
else
this.conn = new WebSocket(url);
// dispatch to the right handlers
this.conn.onmessage = function(evt){
dispatch('message', evt.data);
};
this.conn.onclose = function(){dispatch('close',null)}
this.conn.onopen = function(){dispatch('open',null)}
};
this.disconnect = function() {
this.conn.close();
};
var dispatch = function(event_name, message){
var chain = callbacks[event_name];
if(typeof chain == 'undefined') return; // no callbacks for this event
for(var i = 0; i < chain.length; i++){
chain[i]( message )
}
}
};
では、メッセージのようなイベントを作成するにはどうすればよいですか。
前もって感謝します！
