workerman类TcpConnection的回调属性onClose

发布时间：2021-12-03 23:40:17编辑：雪饮阅读（）

 onClose

说明:
callback Connection::$onClose
此回调与Worker::$onClose回调作用相同，区别是只针对当前连接有效,也就是可以针对某个连接的设置onClose回调。
 
实例1：
<?php
use Workerman\Worker;
use Workerman\Connection\TcpConnection;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker('websocket://0.0.0.0:8484');
// 当有链接事件时触发
$worker->onConnect = function(TcpConnection $connection)
{
    // 设置连接的onClose回调
    $connection->onClose = function(TcpConnection $connection)
    {
        echo "connection closed\n";
    };
};
// 运行worker
Worker::runAll();
?>
 
实例1运行并有客户端主动触发close事件时：
[root@izj6c2jeancylo0ppo4vz5z workerman]# php test.php start
Workerman[test.php] start in DEBUG mode
------------------------------------------- WORKERMAN --------------------------------------------
Workerman version:4.0.22          PHP version:7.0.33
-------------------------------------------- WORKERS ---------------------------------------------
proto   user            worker          listen                      processes    status
tcp     root            none            websocket://0.0.0.0:8484    1             [OK]
--------------------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
connection closed
 
实例2：
<?php
use Workerman\Worker;
use Workerman\Connection\TcpConnection;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker('websocket://0.0.0.0:8484');
// 设置所有连接的onclose回调
$worker->onClose = function(TcpConnection $connection)
{
    echo "connection closed\n";
};
// 运行worker
Worker::runAll();
?>
同实例1效果相同，在实例2运行并有客户端主动close触发时：
[root@izj6c2jeancylo0ppo4vz5z workerman]# php test.php start
Workerman[test.php] start in DEBUG mode
------------------------------------------- WORKERMAN --------------------------------------------
Workerman version:4.0.22          PHP version:7.0.33
-------------------------------------------- WORKERS ---------------------------------------------
proto   user            worker          listen                      processes    status
tcp     root            none            websocket://0.0.0.0:8484    1             [OK]
--------------------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
connection closed
