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
一、安装workerman
composer require workerman/workerman
二、生成命令文件
php artisan make:command Workerman
修改文件
namespace App\Console\Commands; | |
use Illuminate\Console\Command; | |
use Workerman\Worker; | |
class Workerman extends Command | |
{ | |
protected $signature = 'Workerman {action} {--daemonize}'; | |
protected $description = 'Command description'; | |
public function __construct() | |
{ | |
parent::__construct(); | |
} | |
public function handle() | |
{ | |
global $argv;//定义全局变量 | |
$arg = $this->argument('action'); | |
$argv[1] = $arg; | |
$argv[2] = $this->option('daemonize') ? '-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){}; | |
Worker::runAll(); | |
} | |
} |
三、启动命令
$ php artisan Workerman start | |
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] |
四、浏览器之间通信
1. HTML代码 两个html做交互
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 ); | |
} |
2. 设置uid
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
3. 向其他用户发送信息
向用户uid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']); | |
} | |
} | |
} |
五、服务器向浏览器通信
1. workeman监听一个本地发送的端口,在启动的时候
//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]; | |
$connection->send($data); | |
// 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 | |
$data = array (‘uid’=>37,’group’=>’admin’, ‘message’=>’发送成功啦’, ‘to_uid’=>36); | |
// 发送数据,注意5678端口是Text协议的端口,Text协议需要在数据末尾加上换行符 | |
fwrite($client, json_encode($data)."\n"); | |
} | |
} |
