laravel使用workerman 用户交互、服务器交互
使用workeman实现浏览器相互通信、服务器浏览器交互
composer require workerman/workerman
php artisan make:command Workerman

'-d' : '';//该参数是以daemon(守护进程)方式启动 global $text_worker; // 创建一个Worker监听2345端口,使用websocket协议通讯 $text_worker = new Worker("websocket://0.0.0.0:2345"); $text_worker->uidConnections = array();//在线用户连接对象 $text_worker->uidInfo = array();//在线用户的用户信息 // 启动4个进程对外提供服务 $text_worker->count = 4; //当启动workerman的时候 触发此方法 $text_worker->onWorkerStart =function(){ }; //当浏览器连接的时候触发此函数 $text_worker->onConnect = function($connection){ }; //向用户发送信息的时候触发 //$connection 当前连接的人的信息 $data 发送的数据 $text_worker->onMessage = function($connection,$data){ }; //浏览器断开链接的时候触发 $text_worker->onClose = function($connection){}; }}
$ php artisan Workerman start --daemonize Deprecated: Directive 'track_errors' is deprecated in Unknown on line 0----------------------- WORKERMAN -----------------------------Workerman version:4.0.19 PHP version:7.2.9------------------------ WORKERS -------------------------------worker listen processes status none websocket://0.0.0.0:2345 4 [ok]
var socket = new WebSocket("ws://localhost:2345//ws"); // 建立连接时触发 建立链接的时候,需要向workerman发送一条指令,告诉他我是谁,使用id或者用户标识作为uid,告诉workerman 例如,当前html 用户id是37 socket.onopen = function(event) { console.log('连接开始...'); socket.send('{"uid":36,"type":'login'}'); } //workerman发送消息的时候,接收并打印 socket.onmessage = function(event) { var msg = event.data; console.log(msg ); }
浏览器发来了用户uid,需要workerman保留一下,网上有文档说在触发的时候保存,还有用session的,我试验了没成功,所有用浏览器建立链接的时候,向workerman发送一条信息来创建uid,在workerman上接收一下
//$connection 当前连接的人的信息 $data 发送的数据$text_worker->onMessage = function($connection,$data){ $data = json_decode($data); if($data['type']=='login'){ $this->create_uid($connection,$data); }};//创建uid方法 public function create_uid($connection,$data){ global $text_worker; $connection->uid = $data['uid']; //保存用户的uid $text_worker->uidConnections["{$connection->uid}"] = $connection; //向自己的浏览器返回创建成功的信息 $connection->send("用户:[{$connection->uid}] 创建成功"); }
这时候浏览器就会出现打印信息
向用户是37的浏览器发送信息
//js代码 socket.send('{"type":"login","to_uid":36,"uid":36,"message":"nihao"}'); //workerman //$connection 当前连接的人的信息 $data 发送的数据 $text_worker->onMessage = function($connection,$data){ $data = json_decode($data,true); var_dump($data); if($data['type']=='login'){ $this->create_uid($connection,$data); } if($data['type']=='send_message'){ $this->send_message($connection,$data); } }; public function send_message($connection,$data){ global $text_worker; if(isset($data['to_uid'])){ var_dump($data['to_uid']); if(isset($text_worker->uidConnections["{$data['to_uid']}"])){ $to_connection=$text_worker->uidConnections["{$data['to_uid']}"]; $to_connection->send($data['uid'].$data['message']); } } }
//当启动workerman的时候 触发此方法 $text_worker->onWorkerStart =function(){ //监听一个内部端口,用来接收服务器的消息,转发给浏览器 $inner_text_worker = new Worker('Text://127.0.0.1:5678'); $inner_text_worker->onMessage = function($connection_admin, $data) { global $text_worker; // $data数组格式,里面有uid,表示向那个uid的页面推送数据 $data = json_decode($data, true); var_dump($data); $to_uid = $data['to_uid']; var_dump($to_uid); // 通过workerman,向uid的页面推送数据 // $ret = sendMessageByUid($uid, $buffer); $connection = $text_worker->uidConnections[$to_uid]; $connection->send($buffer); // 返回推送结果 $connection_admin->send(true ? 'ok' : 'fail'); }; $inner_text_worker->listen(); };//控制器代码class TestController extends Controller{ public function send(){ $client = stream_socket_client('tcp://127.0.0.1:5678', $errno, $errmsg, 1); // 推送的数据,包含用户,表示是给这个用户推送 $data = array('uid'=>37,'group'=>'admin', 'message'=>'发送成功啦'); // 发送数据,注意5678端口是Text协议的端口,Text协议需要在数据末尾加上换行符 fwrite($client, json_encode($data)."\n");}}
