PHP は swoole を使用してクライアント データをリアルタイムで更新します

if(ws === null){
var wsServer = 'ws://'+ location.hostname +':8888';
ws = new WebSocket(wsServer);
ws.onopen = function(){
console.log("socket连接已打开");
};
ws.onmessage = function(e){
console.log("message:" + e.data);
};
ws.onclose = function(){
console.log("socket连接已断开");
};
ws.onerror = function(e){
console.log("ERROR:" + e.data);
};
//离开页面时关闭连接
$(window).bind('beforeunload',function(){
ws.close();
}
);
}

$server = new swoole_websocket_server("0.0.0.0", 8888);
$server->on('open', function (swoole_websocket_server $server, $request) {
echo "server: handshake success with fd{$request->fd}\n";
});
$server->on('message', function (swoole_websocket_server $server, $frame) {
echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";
$server->push($frame->fd, "this is server");
});
$server->on('close', function ($ser, $fd) {
echo "client {$fd} closed\n";
});
$server->start();
