GatewayWorker+Laravel demo

GatewayWorker 結合 Laravel 使用的簡單案例，重點是在Laravel中使用GatewayClient發送消息

主要流程：GatewayWorker主要負責推送消息給客戶端但不接受客戶端數據，Laravel主要負責接受客戶端數據並處理業務邏輯，而後使用GatewayClient推送數據，

示意圖拿一個官方圖片哈 http://www.workerman.net/gatewaydoc/work-with-other-frameworks/README.html

跟Laravel結合使用的優勢：

1，當 GatewayWorker服務運行時，修改了Laravel業務代碼，直接推送業務相關代碼到服務器上便可，不用重啓GatewayWorker服務；

2，能夠盡情使用Laravel提供的各類便利工具處理數據和業務邏輯；

 

整個項目壓縮文件太大不便上傳，接下來直接貼代碼咯，

本地windows使用步驟：

1，啓動GatewayWorker，雙擊 start_for_win.bat

2，新建一個虛擬域名路徑指定到該項目public目錄

3，開兩個瀏覽器頁面就能互發消息了，以下面兩個效果圖，

效果圖：

項目結構：

ChatServer目錄下的4個start_*.php文件是直接複製的官方demo https://github.com/walkor/workerman-chat/tree/master/Applications/Chat

 composer.json 的 require 部分

    "require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.5.*",
        "laravel/tinker": "~1.0",
        "workerman/gateway-worker" : ">=3.0.0",
        "workerman/gatewayclient": "^3.0"
    },

 

start_for_win.bat  本地windows啓動腳本 

php app\ChatServer\start_register.php app\ChatServer\start_web.php app\ChatServer\start_gateway.php app\ChatServer\start_businessworker.php
pause

 start.php  服務器上的啓動腳本

<?php
/**
 * run with command 
 * php start.php start
 */

ini_set('display_errors', 'on');
use Workerman\Worker;

if(strpos(strtolower(PHP_OS), 'win') === 0)
{
    exit("start.php not support windows, please use start_for_win.bat\n");
}

// 檢查擴展
if(!extension_loaded('pcntl'))
{
    exit("Please install pcntl extension. See http://doc3.workerman.net/appendices/install-extension.html\n");
}

if(!extension_loaded('posix'))
{
    exit("Please install posix extension. See http://doc3.workerman.net/appendices/install-extension.html\n");
}

// 標記是全局啓動
define('GLOBAL_START', 1);

require_once __DIR__ . '/vendor/autoload.php';

// 加載全部application/*/start.php，以便啓動全部服務
foreach(glob(__DIR__.'/app/ChatServer/start*.php') as $start_file)
{
    require_once $start_file;
}
// 運行全部服務
Worker::runAll();

Events.php  參考 http://www.workerman.net/gatewaydoc/work-with-other-frameworks/README.html

<?php

/**
 * 用於檢測業務代碼死循環或者長時間阻塞等問題
 * 若是發現業務卡死，能夠將下面declare打開（去掉//註釋），並執行php start.php reload
 * 而後觀察一段時間workerman.log看是否有process_timeout異常
 */
//declare(ticks=1);

use \GatewayWorker\Lib\Gateway;
class Events
{
    // 當有客戶端鏈接時，將client_id返回，讓mvc框架判斷當前uid並執行綁定
    public static function onConnect($client_id)
    {
        Gateway::sendToClient($client_id, json_encode(array(
            'type'      => 'init',
            'client_id' => $client_id
        )));
    }

    // GatewayWorker建議不作任何業務邏輯，onMessage留空便可
    public static function onMessage($client_id, $message)
    {

    }
}

IndexController.php  發送消息用的控制器 參考 http://www.workerman.net/gatewaydoc/work-with-other-frameworks/README.html

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use GatewayClient\Gateway;

class IndexController extends Controller
{
    public function __construct()
    {
        Gateway::$registerAddress = '127.0.0.1:1236';
    }

    /**
     * web客戶端
     * @param string $uid
     * @param string $to_uid
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
     */
    public function client()
    {
        return view('client');
    }

    /**
     * 綁定uid
     * @return mixed
     */
    public function bind()
    {
        // 假設用戶已經登陸，用戶uid和羣組id在session中
        $uid = request('uid');
        $client_id = request('client_id');

        $res = request()->all();
        $res['type'] = 'bind';
        $res['time'] = date('H:i:s');
        // client_id與uid綁定
        Gateway::bindUid($client_id, $uid);
        Gateway::sendToUid($uid, json_encode($res));
        return response()->json($res);
    }

    /**
     * 發送消息
     * @return mixed
     */
    public function send()
    {
        $uid = request('uid');
        $to_uid = request('to_uid');
        $res = request()->all();
        $res['type'] = 'send';
        $res['time'] = date('H:i:s');
        // 向任意uid的網站頁面發送數據
        Gateway::sendToUid($uid, json_encode($res));
        Gateway::sendToUid($to_uid, json_encode($res));
        return response()->json($res);
    }
}

web.php  路由 

<?php

/*

| routes are loaded by the RouteServiceProvider within a group which

*/

Route::get('/', function () {
    return view('welcome');
});

Route::match(['post', 'get'], 'index/index/{uid}/{to_uid}', 'IndexController@client');

Route::match(['post', 'get'], 'index/client/{uid}/{to_uid}', 'IndexController@client');
