Use of WorkerMan Connection class (with code)

The following column workerman Tutorial will introduce you to the use of the WorkerMan Connection class. I hope it will be helpful to friends in need!

1. Use of TcpConnection class

1. Simple TCP test

Server.php

<?php
require_once __DIR__.&#39;/Workerman/Autoloader.php&#39;;
use Workerman\Worker;
$worker = new Worker(&#39;websocket://0.0.0.0:80&#39;);// 连接回调
$worker->onConnect = function ($connection){
     echo "connection success\n";
};
// 接受发送消息
$worker->onMessage = function ($conn,$data){
    $conn->send("Hello World");
};
// 关闭连接
$worker->onClose = function ($connection){
    echo "connection close \n";
};
$worker::runAll();

Test results:

Server output:

The following errors indicate that the connection protocol inside The reason has not been modified.

www@iZ23s8agtagZ:~$ telnet 127.0.0.1 8085
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
^[[A^[[A
HTTP/1.1 400 Bad Request

<b>400 Bad Request</b><br>Invalid handshake data for websocket. <br> See <a href="http://wiki.workerman.net/Error1">http://wiki.workerman.net/Error1</a> for detail.Connection closed by foreign host.

2. Access to black and white lists

Server.php

<?php
require_once __DIR__.&#39;/Workerman/Autoloader.php&#39;;
use Workerman\Worker;
$worker = new Worker(&#39;tcp://0.0.0.0:8085&#39;);
// 连接回调
$worker->onConnect = function ($connection){
    // IP 白名单验证
    if($connection->getRemoteIP() != &#39;127.0.0.1&#39;){
        $connection->close("IP Address Forbidden");
    }
};
// 接受发送消息
$worker->onMessage = function ($conn,$data){
    $conn->send("Hello World");
};
// 关闭连接
$worker->onClose = function ($connection){
    echo "connection close \n";
};
$worker::runAll();

Open Workerman service

Correct access ：

##Non-local address access:

2. The use of AsyncTcpConnection class

Server.php

<?php
require_once __DIR__.&#39;/Workerman/Autoloader.php&#39;;
use Workerman\Worker;
$worker = new Worker(&#39;websocket://0.0.0.0:443&#39;);
// Workerman 启动的回调,这里传递的是Worker对象
$worker->onWorkerStart = function ($worker){
    echo "onWorkerStart success";
};
// 连接回调
$worker->onConnect = function ($connection){
    $connection_baidu = new \Workerman\Connection\AsyncTcpConnection(&#39;tcp://www.baidu.com:443&#39;);
    // 百度的数据发送给浏览器。返回数据后,使用的数据要use 进来，
    $connection_baidu->onMessage = function ($connection_baidu,$data) use ($connection){
        $connection->send($data);
    };
    // 浏览器接受的数据发送给百度
    $connection->onMessage = function ($connection,$data) use ($connection_baidu){
        $connection_baidu->send($data);
    };
    $connection_baidu->connect();
};
// 接受发送消息
$worker->onMessage = function ($conn,$data){
    $conn->send("Hello World");
};
// 关闭连接
$worker->onClose = function ($connection){
    echo "connection close \n";
};

//Workerman 停止回调
$worker->onWorkerStop = function ($worker){
    echo "onWorkerStop success";
};
$worker::runAll();
