GatewayWorker+Laravel demo

GatewayWorker 结合 Laravel 使用的简单案例，重点是在Laravel中使用GatewayClient发送消息

主要流程：GatewayWorker主要负责推送消息给客户端但不接受客户端数据，Laravel主要负责接受客户端数据并处理业务逻辑，然后使用GatewayClient推送数据，

示意图拿一个官方图片哈 http://www.workerman.net/gatewaydoc/work-with-other-frameworks/README.html

跟Laravel结合使用的优点：

1，当 GatewayWorker服务运行时，修改了Laravel业务代码，直接推送业务相关代码到服务器上即可，不用重启GatewayWorker服务；

2，可以尽情使用Laravel提供的各种便利工具处理数据和业务逻辑；

整个项目压缩文件太大不便上传，接下来直接贴代码咯，

本地windows使用步骤：

1，启动GatewayWorker，双击 start_for_win.bat

2，新建一个虚拟域名路径指定到该项目public目录

3，开两个浏览器页面就能互发消息了，如下面两个效果图，

效果图：

项目结构：

ChatServer目录下的4个start_*.php文件是直接复制的官方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启动脚本 

php appChatServerstart_register.php appChatServerstart_web.php appChatServerstart_gateway.php appChatServerstart_businessworker.php
pause

 start.php  服务器上的启动脚本

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

ini_set('display_errors', 'on');
use WorkermanWorker;

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

// 检查扩展
if(!extension_loaded('pcntl'))
{
    exit("Please install pcntl extension. See http://doc3.workerman.net/appendices/install-extension.html
");
}

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

// 标记是全局启动
define('GLOBAL_START', 1);

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

// 加载所有application/*/start.php，以便启动所有服务
foreach(glob(__DIR__.'/app/ChatServer/start*.php') as $start_file)
{
    require_once $start_file;
}
// 运行所有服务
Worker::runAll();

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

<?php

/**
 * 用于检测业务代码死循环或者长时间阻塞等问题
 * 如果发现业务卡死，可以将下面declare打开（去掉//注释），并执行php start.php reload
 * 然后观察一段时间workerman.log看是否有process_timeout异常
 */
//declare(ticks=1);

use GatewayWorkerLibGateway;
class Events
{
    // 当有客户端连接时，将client_id返回，让mvc框架判断当前uid并执行绑定
    public static function onConnect($client_id)
    {
        Gateway::sendToClient($client_id, json_encode(array(
            'type'      => 'init',
            'client_id' => $client_id
        )));
    }

    // GatewayWorker建议不做任何业务逻辑，onMessage留空即可
    public static function onMessage($client_id, $message)
    {

    }
}

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

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use GatewayClientGateway;

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

    /**
     * web客户端
     * @param string $uid
     * @param string $to_uid
     * @return IlluminateContractsViewFactory|IlluminateViewView
     */
    public function client()
    {
        return view('client');
    }

    /**
     * 绑定uid
     * @return mixed
     */
    public function bind()
    {
        // 假设用户已经登录，用户uid和群组id在session中
        $uid = request('uid');
        $client_id = request('client_id');

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

    /**
     * 发送消息
     * @return mixed
     */
    public function send()
    {
        $uid = request('uid');
        $to_uid = request('to_uid');
        $res = request()->all();
        $res['type'] = 'send';
        $res['time'] = date('H:i:s');
        // 向任意uid的网站页面发送数据
        Gateway::sendToUid($uid, json_encode($res));
        Gateway::sendToUid($to_uid, json_encode($res));
        return response()->json($res);
    }
}

web.php  路由 

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

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');

Route::match(['post', 'get'], 'index/bind', 'IndexController@bind');

Route::match(['post', 'get'], 'index/send', 'IndexController@send');
