The following tutorial column of laravel will introduce laravel to use workerman user interaction and server interaction. I hope it will be helpful to friends in need!
Laravel uses workeman for user interaction and server interaction
Uses workeman to achieve mutual browser communication and server browser interaction
composer require workerman/workerman
php artisan make:command Workerman
Modify file
<?php
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){};
}}
$ 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 );
}
The browser sent the user uid, which needs to be saved by Workerman. There are documents on the Internet that say to save when triggered, and some use session. I tried it without success, so I used the browser. When establishing a link, send a message to workererman to create uid, and receive it on workererman
//$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");
}
At this time, the browser will display a print message
Send information to the browser where the user is 37
//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");}}
If there are any deficiencies, please correct me! Thanks!
