PHP+swoole实现简单多人在线聊天群发

由于本文的能力有限，有好多聊天逻辑的细节没有实现，只实现了群发，具体代码如下所示：

php代码：

$serv = new swoole_websocket_server("127.0.0.1",3999);
//服务的基本设置
$serv->set(array(
'worker_num' => 2,
'reactor_num'=>8,
'task_worker_num'=>1,
'dispatch_mode' => 2,
'debug_mode'=> 1,
'daemonize' => true,
'log_file' => __DIR__.'/log/webs_swoole.log',
'heartbeat_check_interval' => 60,
'heartbeat_idle_time' => 600,
));
$serv->on('connect', function ($serv,$fd){
// echo "client:$fd Connect.".PHP_EOL;
});
//测试receive
$serv->on("receive",function(swoole_server $serv,$fd,$from_id,$data){
// echo "receive#{$from_id}: receive $data ".PHP_EOL;
});
$serv->on('open', function($server, $req) {
// echo "server#{$server->worker_pid}: handshake success with fd#{$req->fd}".PHP_EOL;;
// echo PHP_EOL;
});
$serv->on('message',function($server,$frame) {
// echo "message: ".$frame->data.PHP_EOL;
$msg=json_decode($frame->data,true);
switch ($msg['type']){
case 'login':
$server->push($frame->fd,"欢迎欢迎~");
break;
default:
break;
}
$msg['fd']=$frame->fd;
$server->task($msg);
});
$serv->on("workerstart",function($server,$workerid){
// echo "workerstart: ".$workerid.PHP_EOL;
// echo PHP_EOL;
});
$serv->on("task","on_task");
$serv->on("finish",function($serv,$task_id,$data){
return ;
});
$serv->on('close', function($server,$fd,$from_id) {
// echo "connection close: ".$fd.PHP_EOL;
// echo PHP_EOL;
});
$serv->start();
function on_task($serv,$task_id,$from_id,$data) {
switch ($data['type']){
case 'login':
$send_msg="说:我来了~";
break;
default:
$send_msg="说:{$data['msg']['speak']}";
break;
}
foreach ($serv->connections as $conn){
if ($conn!=$data['fd']){
if (strpos($data['msg']['name'],"游客")===0){
$name=$data['msg']['name']."_".$data['fd'];
}else{
$name=$data['msg']['name'];
}
}else{
$name="我";
}
$serv->push($conn,$name.$send_msg);
}
return;
}
function on_finish($serv,$task_id,$data){
return true;
}

前端代码：

<meta http-equiv="Content-Type" c src="jquery-1.12.0.min.js"> 



<h2>WebSocket Test</h2> 
昵称：<input type="text" size="5" value="游客"> <input type="text"> 
<button rows="10" cols="50"> 
<div></div>
 
<script language="javascript" type="text/javascript"> 
var wsUri ="ws://127.0.0.1:3999/"; 
var output; 
function init() { 
output = document.getElementById("output"); 
testWebSocket();
}
function testWebSocket() { 
websocket = new WebSocket(wsUri); 
websocket.onopen = function(evt) { 
onOpen(evt) 
}; 
websocket.onclose = function(evt) { 
onClose(evt) 
}; 
websocket.onmessage = function(evt) { 
onMessage(evt) 
}; 
websocket.onerror = function(evt) { 
onError(evt) 
}; 
}
function get_speak_msg(){
var name=document.getElementById("name").value;
var speak=document.getElementById("content").value;
var js
return json_msg;
}
function pack_msg(type,msg){
return '{"type":"'+type+'","msg":'+msg+'}';
}
function onOpen(evt) {
append_speak("已经联通服务器.........");
speak_msg=get_speak_msg();
send_msg=pack_msg("login",speak_msg);
doSend(send_msg);
}
function onClose(evt) { 
append_speak("俺老孙去也！");
} 
function onMessage(evt) {
append_speak(evt.data);
}
function onError(evt) {
alert(evt.data);
}
function doSend(message) { 
websocket.send(message);
}
function append_speak(new_msg){
document.getElementById("message").value=document.getElementById("message").value+new_msg+"\n";
document.getElementById('message').scrollTop = document.getElementById('message').scrollHeight;
}
function speak_to_all(){
send_msg=pack_msg("speak",get_speak_msg());
if(document.getElementById("content").value==""){
return;
}
doSend(send_msg);
document.getElementById("content").value="";
}
init();
</script>
</button>
