websocket的推送在控制器中调用和实现

首先，websocket是基于Server的子类，所以可以调用Server的一部分方法，但是需要监听其他的端口，并在控制器中加载调用swoole_client方法

话不多说，上代码；

封装的web_socket.php

<?php

namespace app\common;
include 'Predis.php';
/**
*    socket面向对象的编译
*/
class Ws
{
    CONST HOST='0.0.0.0';
    CONST PORT='9501';
    public $ws=null;
    public $getmsg=null;
    public $server=null;

    public function __construct()
    {   
        $this->ws=new \swoole_websocket_server(self::HOST,self::PORT);
        $this->ws->set([
            //启动task必须要设置其数量
            'worker_num' => 4,
            'task_worker_num' => 4,
        ]);
        //监听新端口
        $this->server=$this->ws->listen("127.0.0.1", 9502, SWOOLE_SOCK_TCP);
        //关闭websocket模式
        $this->server->set([
            'open_websocket_protocol' => false,
        ]);

        $this->ws->on("start", [$this, 'onStart']);
        $this->ws->on('open',[$this,'onopen']);
        $this->server->on("receive", [$this, 'onReceive']);
        $this->server->on("close", [$this, 'onclose']);
        $this->ws->on('message',[$this,'onmessage']);
        $this->ws->on('task',[$this,'onTask']);
        $this->ws->on('finish',[$this,'onFinish']);
        $this->ws->on('close',[$this,'onclose']);
        $this->ws->start();
    }
    //监听数据接收事件
    public function onReceive($serv, $fd, $from_id, $data)
    {
        $this->ws->push(Predis::getInstance()->get('fd'), $data);
    }
    /**
     * 设置进程名，为后续平滑重启进程
     * @param $server
     */

        swoole_set_process_name("live_master");
    }      
   /**

    */
    public function onopen($server, $request)
    {
        Predis::getInstance()->set('fd',$request->fd);
        $server->push($request->fd,'小子，面向对象你也连接成功了');
    }
    
    /**
        监听接收事件的回调
    */
    public function onmessage($server, $frame)
    {
        $server->push($frame->fd, "{$frame->data}");
    }
    /**
        监听关闭事件的回调
    */
    public function onclose($ser, $fd)
    {
        print_r("你好,我的{$fd}\n");
    }

    /**

    *   $data           是任务的内容
    */
     public function onTask($serv,$task_id,$src_worker_id,$data)
    {
        //在终端输出
        print_r($data).'/n';
        //执行耗时任务
        sleep(10);
        //回调于onFinish
        return '你成了-A';
    }
    /**
    *   $task_id        是任务的ID
    *   $data           是任务处理的结果内容
    */
     public function onFinish($serv,$task_id,$data)
    {
        print_r($data).'/n';
    }

}
