    php 使用workerman/gateway制作聊天

    正文概述 转载于：掘金(大鸟成鹏)   2021-01-21   588

    这次使用的是laravel框架：

    1、安装workerman/gateway-worker

    终端项目目录下输入：

    composer require workerman/gateway-worker

    2、创建workerman启动文件

    php artisan make:command Workerman

    <?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use GatewayWorker\BusinessWorker;
use GatewayWorker\Gateway;
use GatewayWorker\Register;
use Workerman\Worker;


class Workerman extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'workerman {action} {--d}';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Start a Workerman server.';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        //
        global $argv;
        $action = $this->argument('action');
 
        $argv[0] = 'artisan workerman';
        $argv[1] = $action;
        $argv[2] = $this->option('d') ? '-d' : '';   //必须是一个-，上面定义命令两个--，后台启动用两个--
 
        $this->start();
    }

    private function start()
    {
        $this->startGateWay();
        $this->startBusinessWorker();
        $this->startRegister();
        Worker::runAll();
    }
 
    private function startBusinessWorker()
    {
        $worker                  = new BusinessWorker();
        $worker->name            = 'BusinessWorker';
        $worker->count           = 1;
        $worker->registerAddress = '127.0.0.1:1236';
        $worker->eventHandler    = \App\GatewayWorker\Events::class;
    }
 
    private function startGateWay()
    {
        $gateway = new Gateway("websocket://0.0.0.0:2346");
        $gateway->name                 = 'Gateway';
        $gateway->count                = 1;
        $gateway->lanIp                = '127.0.0.1';
        $gateway->startPort            = 2300;
        $gateway->pingInterval         = 30;
        $gateway->pingNotResponseLimit = 0;
        $gateway->pingData             = '{"type":"ping"}';
        $gateway->registerAddress      = '127.0.0.1:1236';
    }
 
    private function startRegister()
    {
        new Register('text://0.0.0.0:1236');
    }

}

    3、创建事件监听文件

    创建一个 app/GatewayWorker/Events.php 文件来监听处理 workman 的各种事件

    <?php
namespace App\GatewayWorker;

use GatewayWorker\Lib\Gateway;
use Illuminate\Support\Facades\Log;


class Events
{
 
    public static function onWorkerStart($businessWorker)
    {
        echo "onWorkerStart\r\n";
    }
 
    public static function onConnect($client_id)
    {
        Gateway::sendToClient($client_id, json_encode(['type' => 'onConnect', 'client_id' => $client_id]));
        // echo $client_id;
        echo $client_id."登陆成功\r\n";
    }
 
    public static function onWebSocketConnect($client_id, $data)
    {
        echo "onWebSocketConnect\r\n";
    }
 
    public static function onMessage($client_id, $message)
    {
         Gateway::sendToClient($client_id,$message);
         echo $message;
        // Gateway::sendToClient($client_id, json_encode(['type' => 'onMessage', 'client_id' => $client_id, 'name' => json_decode($message)->name]));
 
        // echo "onMessage\r\n";
    }
 
    public static function onClose($client_id)
    {
        Log::info('Workerman close connection' . $client_id);
        echo "onClose\r\n";
    }
 
}

    4、测试。启动workerman服务端

    php artisan workerman start --d

     在浏览器 F12 打开调试模式，在 Console 里输入

    ws = new WebSocket("ws://ipaddress:2346");
    ws.onopen = function() {
        ws . send('{"name":"one","user_id":"111"}');
        ws . send('{"name":"two","user_id":"222"}');
    };
    ws.onmessage = function(e) {
        console.log("收到服务端的消息：" + e.data);
    };
    ws.onclose = function(e) {
        console.log("服务已断开" );
    }

    console收到服务器端的消息.....

    如在控制器里使用，需要

    public function __construct()
{
        // 设置GatewayWorker服务的Register服务ip和端口，请根据实际情况改成实际值(ip不能是0.0.0.0)
    Gateway::$registerAddress = '127.0.0.1:1236';
 
}

    doc2.workerman.net/

    5、长链接使用代码

    后端：

    <?php

namespace App\Http\Controllers\chat;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Redis;
use App\GatewayWorker\Events;
use GatewayWorker\Lib\Gateway;

class Chat
{
    public function __construct()
    {
        // 设置GatewayWorker服务的Register服务ip和端口，请根据实际情况改成实际值(ip不能是0.0.0.0)
        Gateway::$registerAddress = '127.0.0.1:1236';
 
    }

    public function talks()
    {
        return view('chat.talks');
    }

    public function talk(Request $request)
    {
        return view('chat.talk');
    }

    public function loginConfirm(Request $request)
    {
        $name = $request->post('name');
        if ($name) {
            $user = Redis::sAdd('name',$name);
            // if ($user) {
                return response()->json(['code'=>200]);
            // }
        }
    }

    public function getList(Request $request)
    {
        $to = $request->get('name');
        $list = Redis::sMembers('name');
        foreach ($list as $k=>$v)
        {
            $unread = Redis::hGet('unread_'.$to, $v);
            $list[$k] = array('name'=>$v, 'unread'=>$unread);
        }
        if ($list) {
            return response()->json(['code'=>200, 'list'=>$list]);
        }
    }

    public function content(Request $request)
    {

        $client_id = $request->post('client_id');
        $content = $request->post('content');
        $from = $request->post('from');
        $to = $request->post('to');
        $plus = strcmp(md5($from), md5($to));
        if ($plus == 0) {
            $res = $from.$to;
        } else if ($plus < 0) {
            $res = $from.$to;
        } else if ($plus >0) {
            $res = $to.$from;
        }
        $data = json_encode(array('from'=>$from, 'to'=>$to, 'message'=>$content, 'time'=>time()),JSON_UNESCAPED_UNICODE,true);
        $keyName = 'mes:'.$res;
        $insert = Redis::rPush($keyName, $data);
        $unread = Redis::hIncrBy('unread_'.$to,$from,1);
        if ($insert&&$unread) {
            Gateway::sendToGroup($res,$data);
            return response()->json(['code'=>200]);
        }

    }

    public function mesList(Request $request)
    {
        $from = $request->get('from');
        $to = $request->get('to');

        $plus = strcmp(md5($from), md5($to));
        if ($plus == 0) {
            $res = $from.$to;
        } else if ($plus < 0) {
            $res = $from.$to;
        } else if ($plus >0) {
            $res = $to.$from;
        }
        
        $list = Redis::lrange('mes:'.$res,-10,-1);
        foreach( $list as $k=>$v) {
            $list[$k] = json_decode($v);
        }
        Redis::hSet('unread_'.$from, $to, 0);
        $client_id = $request->get('client_id');
        Gateway::joinGroup($client_id, $res);
        return response()->json(['code'=>200, 'list'=>$list]);
    }

    public function mesRead(Request $request)
    {
        $from = $request->input('from');
        $to = $request->input('to');
        Redis::hSet('unread_'.$from, $to, 0);
    }
}
