  1. redis生產者釋出

    php artisan make:command Redis/PublishCommand

  2. redis消費者訂閱

    php artisan make:command Redis/SubCommand

  3. 啟動websocket

    php artisan ws
<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Facades\Redis;
use App\Facades\MyRedis;

class WebSocket extends Command
{
    protected $signature = 'ws';

    protected $ws;

    public function __construct()
    {
        parent::__construct();
    }

    public function handle()
    {
        //建立websocket伺服器物件，監聽0.0.0.0:9502埠，開啟SSL隧道
        $this->ws = new \swoole_websocket_server("0.0.0.0", 9502, SWOOLE_PROCESS, SWOOLE_SOCK_TCP | SWOOLE_SSL);

        //配置引數
        $this->ws ->set([
            'daemonize' => false, //守護程式化。
            //配置SSL證照和金鑰路徑
            'ssl_cert_file' => env('SSL_CERT_FILE'),
            'ssl_key_file'  => env('SSL_KEY_FILE')
        ]);

        $this->ws->on("open", function (\Swoole\WebSocket\Server $ws, \Swoole\Http\Request $request) {
//            dump($request->fd, $request->get, $request->server);
            $ws->push($request->fd, "連線成功\n");
        });

        $this->ws->on("message", function (\Swoole\WebSocket\Server $ws, $frame) {
//            dump("訊息: {$frame->data}\n");
            $ws->push($frame->fd, "服務端回覆: {$frame->data}\n");
        });

        //監聽WebSocket主動推送訊息事件
        $this->ws->on('request', function ($request, $response) {
            $data = $request->post;
            //$this->ws->connections 遍歷所有websocket連線使用者的fd，給所有使用者推送
            foreach ($this->ws->connections as $fd) {
                if ($this->ws->isEstablished($fd)) {
                    $this->ws->push($fd, json_encode($data));
                }
            }
        });

        $this->ws->on("close", function (\Swoole\WebSocket\Server $ws, $fd) {
            dump("{$fd}關閉");
        });

        $this->ws->start();
    }

}
  1. 啟動redis消費者訂閱
    php artisan sub:info
<?php

namespace App\Console\Commands\Redis;

use App\Facades\MyRedis;
use Illuminate\Console\Command;

class SubCommand extends Command
{

    protected $signature = 'sub:info';


    protected $description = 'redis消費者訂閱';


    public function __construct()
    {
        parent::__construct();
    }


    public function handle()
    {
        MyRedis::subScribe();
        $this->comment('sub successful');
    }
}
  1. h5頁面連線websocket

        websocket.onopen = function (evt) {
            console.log("Connected to WebSocket server.");
        };

        websocket.onclose = function (evt) {
            console.log("Disconnected");
        };

        websocket.onmessage = function (evt) {
            console.log('Retrieved data from server: ' + evt.data);
        };

        websocket.onerror = function (evt, e) {
            console.log('Error occured: ' + evt.data);
        };

守護程式

  1. 藉助 nohup 和 & 配合使用
    nohup php artisan sub:info &
  2. 通過 fg 命令讓程式恢復到普通佔用控制檯的模式
    fg

關閉程式

netstat -anp | grep 9502
kill -9 1682674
