Question

在laravel 5.7应用程序中，我使用了一些在线文档安装了cboden / ratchet

composer.json :
    "type": "project",
    "require": {
        ...
        "cboden/ratchet": "^0.4.1",

使用app / Classes / Socket / Base / BaseSocket.php：

<?php
namespace App\Classes\Socket\Base;

use Rachet\MessageComponentInterface;
use Rachet\ConnectionInterface;

class BaseSocket implements MessageComponentInterface {

    public function onOpen(ConnectionInterface $conn) {

    }

    public function onMessage(ConnectionInterface $conn, $mgs) {

    }

    public function onClose(ConnectionInterface $conn) {

    }

    public function onError(ConnectionInterface $conn, \Exception $e) {

    }

}

和控制台命令app / Console / Commands / ChatServer.php：

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;

use Ratchet\Http\HttpServer;
use Ratchet\Server\IoServer;
use Ratchet\WebSocket\WsServer;
use App\Classes\Socket\ChatSocket;

class ChatServer extends Command
{
    protected $signature = 'chat_server:serve';

    protected $description = 'chat_server description';

    public function __construct()
    {
        parent::__construct();
    }

    public function handle()
    {
        $this->info("Start server!");
        $server= IoServer::factory(
            new HttpServer(
                new WsServer(
                    new ChatSocket()
                )
            ),
            8080
        );

        $server->run();
    }
}

但是在控制台中运行命令时出现错误：

$ php artisan chat_server:serve
Start server!

     8| 
     9|     public function onOpen(ConnectionInterface $conn) {
    10| 
    11|     }

我错过了一些声明吗？还是要在app.php中添加声明？如果我有添加配置声明，我会错过阅读文档吗？

更新的块＃2：

搜索决策时，我发现我需要创建自己的服务提供商，以便在Laravel中正确注册它我要为“ cboden / ratchet”创建自己的服务提供商，应该执行哪些步骤？这是出于我的幼虫经验...

谢谢！

看起来像拼写错误。必须是：

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

使用cboden / ratchet我发现接口'Rachet \ MessageComponentInterface'未找到错误
