我如何在基于 google websocket 的聊天系统中对客户端进行身份验证，以便只有有效用户才能发送消息？

我想要客户端请求仅在验证连接后才建立连接。

服务器端代码......

  <?php
// prevent the server from timing out
set_time_limit(0);
include("database.php");

// 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;
    $ip = long2ip( $Server->wsClients[$clientID][6] );

    // check if message length is 0
    if ($messageLength == 0 or trim($message)=='') {
        $Server->wsClose($clientID);
        return;
    }
    // check if either it is valid msg or not
    if (!(substr($message,0,5)=='12345')) {
        $Server->wsSend($clientID, "You are not a valid user so you can not send message.");
        $Server->wsClose($clientID);
        return;
    }


    //The speaker is the only person in the room. Don't let them feel lonely.
    if ( sizeof($Server->wsClients) == 1 )
    {  
        mysql_query( "INSERT INTO message VALUES ( null,1000000000,2000000000,'$message',null )") or die(mysql_error()); 
        $Server->wsSend($clientID, "You  are  alone in chat room");
    }
    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\"");
        {

        mysql_query( "INSERT INTO message VALUES ( null,1000000000,2000000000,'$message',null )") or die(mysql_error()); 
        $Server->wsSend($id, " ($ip)  \"$message\"");

        }





}

// when a client connects
function wsOnOpen($clientID)
{
    global $Server;
    $ip = long2ip( $Server->wsClients[$clientID][6] );

    $Server->log( "$ip ($clientID) has connected." );

    //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.");
}

// start the server
$Server = new PHPWebSocket();
$Server->bind('message', 'wsOnMessage');
$Server->bind('open', 'wsOnOpen');
$Server->bind('close', 'wsOnClose');
// for other computers to connect, you will probably need to change this to your LAN IP or external IP,
// alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME']))
$Server->wsStartServer('127.0.0.1', 9300);

            //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 );
        }

        $(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 );

                    log(  $('#name').val()+" ---> " + this.value );

                    send( $('#key').val()+ $('#name').val()+" ---> " + 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.connect();
        });
    </script>

最佳答案

据我所知，您可以通过 WebSocket 使用标准 HTTP 身份验证机制。
