我正在尝试使用HTML5/JS API创建一个简单的WebSocket示例。根据我在服务器上追踪的内容,看起来套接字正在连接,但没有任何事件触发(onopen,onmessage,onclose等)。我是Flash开发人员,所以我不擅长调试JavaScript,我希望有人能帮助我。这是我正在使用的客户端代码。WebSocket不会触发事件
<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>
这里是我的套接字服务器代码(它可以在Flash中正常工作,但这可能并不意味着什么)。
<?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";
}
}
?>
在此先感谢。
