phpsocket.io 中认证失败的客户端连接如何服务端主动断开

609176445

我修改启动脚本如下,@walkor ,帮忙看看要怎么断开非法的请求连接呢?

<?php
use Workerman\Worker;

// composer autoload

    $socket->auth = false;
    \Workerman\Lib\Timer::add(1, function () use ($socket, $io) {
        if (!$socket->auth && $socket) {
            unset($socket);
        }
    }, [], false);

    $socket->on("doauth", function ($account) use ($socket) {
        //do auth
        $account = @json_decode($account, true);
        if (!is_array($account)) {
            $socket->emit("auth fail", );
            unset($socket);
            return;
        } elseif ($account != USER || $account != PWD) {
            $socket->emit("auth fail", );
            unset($socket);
            return;
        }

socket.io好像没有关闭链接的方法。

有个 socket.io-auth 好像是服务端直接disconnect客户端连接。不然直接部署到线上,任何非法连接不授权都可以很容易被攻击挂了,我用PHP unset socket好像连接都还在。不知道有没办法实现
