webman 利用tcp 做服务端对接物联网

用webman 建立tcp 的服务端

安装webman

安装 composer require webman/gateway-worker

文件：config/plugin/webman/gateway-worker/process.php

这里定义了两个协议，tcp 用来对接物联网，ws 用来对接im

<?phpuse Webman\GatewayWorker\Gateway;
use Webman\GatewayWorker\BusinessWorker;
use Webman\GatewayWorker\Register;return ['gateway' => ['handler'     => Gateway::class,'listen'      => 'websocket://0.0.0.0:7272','count'       => 2,'reloadable'  => false,'constructor' => ['config' => ['lanIp'           => '127.0.0.1','startPort'       => 2300,'pingInterval'    => 25,'pingData'        => '{"type":"ping"}','registerAddress' => '127.0.0.1:1236','onConnect'       => function(){},]]],'gateway-tcp' => [ // 假设增加一个tcp端口的gateway进程'handler'     => Gateway::class,'listen'      => 'tcp://0.0.0.0:8383', //  注意这里端口不能重复'count'       => cpu_count(),'reloadable'  => false,'constructor' => ['config' => ['lanIp'           => '127.0.0.1','startPort'       => 3300, // 注意这里端口不能重复，步数大大一些，不能和上面2300太接近'pingInterval'    => 25,'pingData'        => '{"type":"ping"}','registerAddress' => '127.0.0.1:1236','onConnect'       => function(){},]]],'worker' => ['handler'     => BusinessWorker::class,'count'       => cpu_count()*2,'constructor' => ['config' => ['eventHandler'    => plugin\webman\gateway\Events::class,'name'            => 'ChatBusinessWorker','registerAddress' => '127.0.0.1:1236',]]],'register' => ['handler'     => Register::class,'listen'      => 'text://127.0.0.1:1236','count'       => 1, // Must be 1'reloadable'  => false,'constructor' => []],
];

文件：plugin/webman/gateway/Events.php

这里im 和 tcp 公用一套，需要注意要根据bind 的uid 来区别

<?phpnamespace plugin\webman\gateway;use GatewayWorker\Lib\Gateway;class Events
{public static function onWorkerStart($worker){}public static function onConnect($client_id){var_dump(5555,$client_id);Gateway::bindUid($client_id, '1');}public static function onWebSocketConnect($client_id, $data){}public static function onMessage($client_id, $message){var_dump(666,$client_id,$message);Gateway::sendToClient($client_id, "receive message $message");}public static function onClose($client_id){}}

文件：controller/IndexController.php

这里是在方法内主动发送数据

<?phpnamespace app\controller;use support\Request;
use GatewayWorker\Lib\Gateway;class IndexController
{public function index(Request $request){$uid='1';//查看是否在线var_dump('是否在线',!!Gateway::isUidOnline($uid));if(Gateway::isUidOnline($uid)){$message = "lizhili--" . date('H:i:s');Gateway::sendToUid($uid, $message . "\n");}return json(['code' => 0, 'msg' => 'ok']);}}
