Swoole——创建TCP服务

启动TCP服务代码

<?php
/**
 * 智慧公厕
 */

namespace Toilet\Action;

class IndexAction extends CommonAction
{
    public function server() {
        //创建Server对象，监听 127.0.0.1:25111端口
        $serv = new \Swoole\Server("127.0.0.1", 25111);

        //监听连接进入事件
        $serv->on('Connect', function ($serv, $fd) {
            echo "Client: Connect.\n";
            setlog([$fd],'','连接','toilet.log');
        });

        //监听数据接收事件
        $serv->on('Receive', function ($serv, $fd, $from_id, $data) {
            $serv->send($fd, "Server: ".$data);
            setlog([$data,$fd,$from_id],'','响应','toilet.log');
        });

        //监听连接关闭事件
        $serv->on('Close', function ($serv, $fd) {
            echo "Client: Close.\n";
            setlog([$fd],'','关闭','toilet.log');
        });

        //启动服务器
        $serv->start();
    }
}

执行

# php toilet.php Index/server
PHP Fatal error:  Class 'Swoole\Server' not found in /home/wwwroot/default/smart/smart-community/Application/Toilet/Action/IndexAction.class.php on line 12

Fatal error: Class 'Swoole\Server' not found in /home/wwwroot/default/smart/smart-community/Application/Toilet/Action/IndexAction.class.php on line 12
Class 'Swoole\Server' not found
FILE: /home/wwwroot/default/smart/smart-community/Application/Toilet/Action/IndexAction.class.php(12)

报错了，因为swoole没有安装

安装swoole后

# php toilet.php Index/server
Client: Connect.

客户端测试

# telnet 127.0.0.1 25111
Trying 127.0.0.1...
