swoole websocket_server 服务（三）

面向过程

<?php

$server = new swoole_websocket_server("0.0.0.0", 9501);

$server->on('open','onOpen');
function onOpen($server, $request)
{
    echo "server: handshake success with fd{$request->fd}\n";
}

$server->on('message','onMessage');
function onMessage($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();

面向对象封装后

<?php
/**
* websocket 封装
*/
class Websocket
{
	CONST HOST = '0.0.0.0';
	CONST PORT =  9501;

	public $ws = null;
	public function __construct()
	{
		$this->ws = new swoole_websocket_server('0.0.0.0', 9501);
		if ($this->ws) {
			$this->ws->set([
				'worker_num'=>2,
				'task_worker_num'=>2
			]);
			$this->ws->on("open", [$this, 'onOpen']);
			$this->ws->on("message", [$this, 'onMessage']);
			$this->ws->on("task", [$this, 'onTask']);
			$this->ws->on("finish", [$this, 'onFinish']);
			$this->ws->on("close", [$this, 'onClose']);
			$this->ws->start();
		}
		

	}

	 * @param  [type] $ws      [description]
	 * @param  [type] $request [description]
	 * @return [type]          [description]
	 */
	public function onOpen($ws,$request)
	{
		swoole_timer_tick(5000,function($timeid){
			echo "timerId:{$timeid}";
		});
		$countent = [
			'date'=>date('Y-m-d H:i:s'),
			'get'=>$request->get,
			'post'=>$request->post,

		];
		swoole_async_writefile(__DIR__.'/access.log',json_encode($countent),function(){},FILE_APPEND);
		var_dump($request->fd);
	}

		swoole_timer_after(500,function() use ($ws,$frame)
		{

	public function onTask($serv,$taskId,$workerId,$data)
	{
		print_r($data);
		sleep(15);
		return "on task finish";
	}

	public function onFinish($serv,$taskId,$data)
	{
		echo "taskId:{$taskId}\n";
		echo "finish-data-success:{$data}\n";
	}

}

$obj = new Websocket();

 swoole定时器 ，每5秒在shell终端打印定时器id

swoole_timer_tick(5000,function($timeid){
	echo "timerId:{$timeid}";
});

swoole文件异步 已追加形式 写入到当前目录下的access.log文件中，

        $countent = [
			'date'=>date('Y-m-d H:i:s'),
			'get'=>$request->get,
			'post'=>$request->post,
			'header'=>$request->header
		];
swoole_async_writefile(__DIR__.'/access.log',json_encode($countent),function({},FILE_APPEND);

swoole异步定制器 ，只执行一次 ; use ($ws,$frame)  闭包函数引入

swoole_timer_after(500,function() use ($ws,$frame)
{
	$ws->push($frame->fd,"5s after:{$frame->fd}");
});

swoole task异步处理事件

$ws->task($data); //看作是发布异步任务

//自动监听task任务，并进行处理
public function onTask($serv,$taskId,$workerId,$data)
{
	print_r($data);
	sleep(15);
	return "on task finish";
}
