【问题描述】：
我是 Web 套接字的新手。我制作了我的第一个 Web 套接字，但现在运行它时遇到问题！
这是socket的代码
// set some variables
$host = "127.0.0.1";
$port = 1234;
// don't timeout!
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
if($socket){
echo "socket created .... $socket\n";
}
// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
if($result){
echo "socket binded ... $result\n";
}
// start listening for connections
$result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
if($result){
echo "socket is now listening ... $result";
}
// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
if($spawn){
echo $spawn."\n";
}
// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");
if($input){
echo $input."\n";
}
// clean up input string
$input = trim($input);
// reverse client input and send back
$output = strrev($input) . "\n";
socket_write($spawn, $output, strlen ($output)) or die("Could not write output\n");
// close sockets
socket_close($spawn);
socket_close($socket);
现在我该如何运行这段代码？？我在我的 xampp shell 上写了以下代码：
php htdocs/socket/server.php -q
它显示：
socket created....Resource id #4
socket binded... 1
socket is now listening...1 Resource is #5
GET socket/server.php HTTP 1.1
upgrade: WebSocket
connection: Upgrade
Host: http://localhost
sec-WebSocket-key1: 14 53 8501 z4 5R'
sec-WebSocket-key2: S 9\ 2s63, *8460!~MO@
现在我该如何运行它.. 我如何向它发送输入以及如何将它与 JavaScript 一起使用？？
我编写了一段 JavaScript 代码，但它连接了一秒钟然后断开连接...
这里是javascipt代码：
$(document).ready(function() {
if(!("WebSocket" in window)){
$('#chatLog, input, button, #examples').fadeOut("fast");
$('<p>Oh no, you need a browser that supports WebSockets. How about <a href="http://www.google.com/chrome">Google Chrome</a>?</p>').appendTo('#container');
}else{
//The user has WebSockets
connect();
function connect(){
var socket;
var host = "ws://localhost:1234/websocket_source_files/myown.php";
try{
var socket = new WebSocket(host);
message('<p class="event">Socket Status: '+socket.readyState);
socket.onopen = function(){
message('<p class="event">Socket Status: '+socket.readyState+' (open)');
}
socket.onmessage = function(msg){
message('<p class="message">Received: '+msg.data);
}
socket.onclose = function(){
message('<p class="event">Socket Status: '+socket.readyState+' (Closed)');
}
} catch(exception){
message('<p>Error'+exception);
}
function send(){
var text = $('#text').val();
if(text==""){
message('<p class="warning">Please enter a message');
return ;
}
try{
socket.send(text);
message('<p class="event">Sent: '+text)
} catch(exception){
message('<p class="warning">');
}
$('#text').val("");
}
function message(msg){
$('#chatLog').append(msg+'</p>');
}//End message()
$('#text').keypress(function(event) {
if (event.keyCode == '13') {
send();
}
});
$('#disconnect').click(function(){
socket.close();
});
}
}//End connect()
});
</script>
<title>WebSockets Client</title>
</head>
<body>
<div id="wrapper">
<div id="container">
<h1>WebSockets Client</h1>
<div id="chatLog">
</div>
<p id="examples">e.g. try 'hi', 'name', 'age', 'today'</p>
<input id="text" type="text" />
<button id="disconnect">Disconnect</button>
</div>
</div>
</body>
</html>
请帮助我运行此代码并学习网络套接字。我真的需要在我的学校项目中使用它们。
