workerman是什么？

Workerman是一个异步事件驱动的PHP框架，具有高性能，可轻松构建快速，可扩展的网络应用程序。支持HTTP，Websocket，SSL和其他自定义协议。支持libevent，HHVM，ReactPHP。

推荐：《workerman教程》

要求

PHP 5.3或更高版本
兼容POSIX的操作系统（Linux，OSX，BSD）
用于PHP的POSIX和PCNTL扩展

安装

composer require workerman/workerman

基本用法

websocket服务器

<?php
require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\Worker;

// 创建一个Websocket服务器
$ws_worker = new Worker("websocket://0.0.0.0:2346");

$ws_worker->count = 4;

// 在新连接到来时发出
$ws_worker->onConnect = function($connection)
{
    echo "New connection\n";
 };

// 接收数据时发出
$ws_worker->onMessage = function($connection, $data)
{
    // Send hello $data
    $connection->send(&#39;hello &#39; . $data);
};

// 连接关闭时发出
$ws_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};

// 运行worker
Worker::runAll();

http服务器

require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\Worker;

// #### http worker ####
$http_worker = new Worker("http://0.0.0.0:2345");

$http_worker->count = 4;

// 接收数据时发出
$http_worker->onMessage = function($connection, $data)
{
    //$_GET、$_POST、$_COOKIE、$_SESSION、$_SERVER、$_FILES都是可用的
    var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
    // 发送数据给客户端
    $connection->send("hello world \n");
};

// 运行所有workers
Worker::runAll();

WebServer

require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\WebServer;
use Workerman\Worker;

// WebServer
$web = new WebServer("http://0.0.0.0:80");

$web->count = 4;

$web->addRoot(&#39;www.your_domain.com&#39;, &#39;/your/path/Web&#39;);
$web->addRoot(&#39;www.another_domain.com&#39;, &#39;/another/path/Web&#39;);

Worker::runAll();

TCP服务器

require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\Worker;

// #### 创建socket并监听1234端口 ####
$tcp_worker = new Worker("tcp://0.0.0.0:1234");

$tcp_worker->count = 4;

//在新连接到来时发出
$tcp_worker->onConnect = function($connection)
{
    echo "New Connection\n";
};

// 接收数据时发出
$tcp_worker->onMessage = function($connection, $data)
{
    // 发送数据给客户端
    $connection->send("hello $data \n");
};

// 在新连接到来时发出
$tcp_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};

Worker::runAll();

启用SSL

<?php
require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\Worker;

// SSL环境
$context = array(
    &#39;ssl&#39; => array(
        &#39;local_cert&#39;  => &#39;/your/path/of/server.pem&#39;,
        &#39;local_pk&#39;    => &#39;/your/path/of/server.key&#39;,
        &#39;verify_peer&#39; => false,
    )
);

// 创建一个带有ssl的Websocket服务器。
$ws_worker = new Worker("websocket://0.0.0.0:2346", $context);

// 启用SSL。WebSocket+SSL意味着安全的WebSocket (wss://)。
//类似的Https方法等等。
$ws_worker->transport = &#39;ssl&#39;;

$ws_worker->onMessage = function($connection, $data)
{
    // 发送hello $data
    $connection->send(&#39;hello &#39; . $data);
};

Worker::runAll();

自定义协议

Protocols/MyTextProtocol.php

namespace Protocols;
/**
 * 用户定义的协议
*格式文本+“\ n”
 */
class MyTextProtocol
{
    public static function input($recv_buffer)
    {
        // 找到“\n”第一个出现的位置
        $pos = strpos($recv_buffer, "\n");
        // 不是一个完整的package。返回0，因为package的长度无法计算
        if($pos === false)
        {
            return 0;
        }
        // 返回package的长度
        return $pos+1;
    }

    public static function decode($recv_buffer)
    {
        return trim($recv_buffer);
    }

    public static function encode($data)
    {
        return $data."\n";
    }
}

require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\Worker;

// #### MyTextProtocol worker ####
$text_worker = new Worker("MyTextProtocol://0.0.0.0:5678");

$text_worker->onConnect = function($connection)
{
    echo "New connection\n";
};

$text_worker->onMessage =  function($connection, $data)
{
    // 发送数据给客户端
    $connection->send("hello world \n");
};

$text_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};

// 运行所有workers
Worker::runAll();

计时器

require_once __DIR__ . &#39;/vendor/autoload.php&#39;;
use Workerman\Worker;
use Workerman\Lib\Timer;

$task = new Worker();
$task->onWorkerStart = function($task)
{
    // 2.5秒
    $time_interval = 2.5; 
    $timer_id = Timer::add($time_interval, 
        function()
        {
            echo "Timer run\n";
        }
    );
};

//运行
Worker::runAll();

    $ws_connection->onConnect = function($connection){
        $connection->send(&#39;hello&#39;);
    };
    $ws_connection->onMessage = function($connection, $data){
        echo "recv: $data\n";
    };
    $ws_connection->onError = function($connection, $code, $msg){
        echo "error: $msg\n";
    };

绝对会话超时有什么区别？May 03, 2025 am 12:21 AM

绝对会话超时从会话创建时开始计时，闲置会话超时则从用户无操作时开始计时。绝对会话超时适用于需要严格控制会话生命周期的场景，如金融应用；闲置会话超时适合希望用户长时间保持会话活跃的应用，如社交媒体。

如果会话在服务器上不起作用，您将采取什么步骤？May 03, 2025 am 12:19 AM

服务器会话失效可以通过以下步骤解决：1.检查服务器配置，确保会话设置正确。2.验证客户端cookies，确认浏览器支持并正确发送。3.检查会话存储服务，如Redis，确保其正常运行。4.审查应用代码，确保会话逻辑正确。通过这些步骤，可以有效诊断和修复会话问题，提升用户体验。

为会话cookie设置httponly标志的重要性是什么？May 03, 2025 am 12:10 AM

设置httponly标志对会话cookie至关重要，因为它能有效防止XSS攻击，保护用户会话信息。具体来说，1）httponly标志阻止JavaScript访问cookie，2）在PHP和Flask中可以通过setcookie和make_response设置该标志，3）尽管不能防范所有攻击，但应作为整体安全策略的一部分。
