如何使“服务器”PHP脚本与其他脚本进行通信

Question

The server script would run continuously.

Other scripts are normal websites, that should be able to communicate with the server script.

I've come across Ratchet ( https://github.com/cboden/Ratchet ), tried the example from here: http://socketo.me/docs/hello-world and it works :D

But the client needs javascript. And I would like to send the request to the server with PHP because the messages are linux commands, and I wouldn't want site visitors to be able to send linux commands to my server script. Also, only messages from scripts from "localhost" should be taken into consideration.

Is it possible to do this with Ratchet? Or are there other solutions for this?

Answer 1

Ratchet doesn't offer a client. I would look at phpwebsocket for your php websocket client.

To ensure that client connections come from localhost in Ratchet, change this bit of code from the Push Integration tutorial:

// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server($loop);
// Binding to 0.0.0.0 means remotes can connect
//$webSock->listen(8080, '0.0.0.0');
// Binding to 127.0.0.1 means the only client that can connect is itself
$webSock->listen(8080, '127.0.0.1');
$webServer = new Ratchet\Server\IoServer(
    new Ratchet\WebSocket\WsServer(
        new Ratchet\Wamp\WampServer(
            $pusher
        )
    ),
    $webSock
);

您需要创建一个代理PHP脚本，它将处理javascript请求并将其转换为您的棘轮脚本的CLI命令。
