我正在嘗試使用HTML5/JS API創建一個簡單的WebSocket示例。根據我在服務器上追蹤的內容,看起來套接字正在連接,但沒有任何事件觸發(onopen,onmessage,onclose等)。我是Flash開發人員,所以我不擅長調試JavaScript,我希望有人能幫助我。這是我正在使用的客戶端代碼。WebSocket不會觸發事件
<script type="text/javascript" charset="utf-8">
function startSocket()
{
if("WebSocket" in window)
{
var ws = new WebSocket("ws://localhost:1740");
ws.onopen = function() {
window.alert("open!");
}
ws.onmessage = function(event) {
window.alert(event.data);
}
ws.onclose = function() {
window.alert("Closed");
}
ws.onerror = function() {
window.alert("trouble in paradise");
}
}
}
</script>
這裏是我的套接字服務器代碼(它可以在Flash中正常工作,但這可能並不意味着什麼)。
<?php
create_connection('localhost',1740);
function create_connection($host,$port)
{
$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
if (!is_resource($socket)) {
echo 'Unable to create socket: '. socket_strerror(socket_last_error()) . PHP_EOL;
} else {
echo "Socket created.\n";
}
if (!socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1)) {
echo 'Unable to set option on socket: '. socket_strerror(socket_last_error()) . PHP_EOL;
} else {
echo "Set options on socket.\n";
}
if (!socket_bind($socket, $host, $port)) {
echo 'Unable to bind socket: '. socket_strerror(socket_last_error()) . PHP_EOL;
} else {
echo "Socket bound to port $port.\n";
}
if (!socket_listen($socket,SOMAXCONN)) {
echo 'Unable to listen on socket: ' . socket_strerror(socket_last_error());
} else {
echo "Listening on the socket.\n";
}
while (true)
{
$connection = @socket_accept($socket);
if($connection)
{
echo "Client $connection connected!\n";
send_data($connection);
} else {
echo "Bad connection.";
}
}
}
function send_data($connection)
{
echo $connection;
// Create a number between 30 and 32 that will be our initial stock price.
$stock_price = rand(30,32);
while (true)
{
socket_write($connection,"$stock_price\n",strlen("$stock_price\n"));
sleep(1);
// Generate a random number that will represent how much our stock price
// will change and then make that number a decimal and attach it to the
// previous price.
$stock_offset = rand(-50,50);
$stock_price = $stock_price + ($stock_offset/100);
echo "$stock_price\n";
}
}
?>
在此先感謝。
