Question

我正在尝试运行Ratchet应用程序演示，但是我收到了这个错误（在标题中）。

我的文件结构：

/bin/chat-server
/bin/push-server
/src/MyApp/Chat.php
/src/MyApp/Pusher.php
/vendor/ ..
composer.json

这是我的Pusher课程，我收到错误：

<?php
namespace MyApp;
use Ratchet\ConnectionInterface;
use Ratchet\Wamp\WampServerInterface;

class Pusher implements WampServerInterface {

    public function onUnSubscribe(ConnectionInterface $conn, $topic) {
    }
    public function onOpen(ConnectionInterface $conn) {
    }
    public function onClose(ConnectionInterface $conn) {
    }
    public function onCall(ConnectionInterface $conn, $id, $topic, array $params) {
        // In this application if clients send data it's because the user hacked around in console
        $conn->callError($id, $topic, 'You are not allowed to make calls')->close();
    }
    public function onPublish(ConnectionInterface $conn, $topic, $event, array $exclude, array $eligible) {
        // In this application if clients send data it's because the user hacked around in console
        $conn->close();
    }
    public function onError(ConnectionInterface $conn, \Exception $e) {
    }


        /**
     * A lookup of all the topics clients have subscribed to
     */
    protected $subscribedTopics = array();

    public function onSubscribe(ConnectionInterface $conn, $topic) {
        $this->subscribedTopics[$topic->getId()] = $topic;
    }

    /**
     * @param string JSON'ified string we'll receive from ZeroMQ
     */
    public function onBlogEntry($entry) {
        $entryData = json_decode($entry, true);

        // If the lookup topic object isn't set there is no one to publish to
        if (!array_key_exists($entryData['category'], $this->subscribedTopics)) {
            return;
        }

        $topic = $this->subscribedTopics[$entryData['category']];

        // re-send the data to all the clients subscribed to that category
        $topic->broadcast($entryData);
    }

    /* The rest of our methods were as they were, omitted from docs to save space */
}

My WampServerInterface位于：

C:\wamp\www\myRatchetTutorial\vendor\cboden\ratchet\src\Ratchet\Wamp\WampServerInterface.php

我尝试将此文件结构重新组织为：

C:\wamp\www\myRatchetTutorial\vendor\Ratchet\Wamp\WampServerInterface.php

但仍然是同样的错误。

任何想法如何解决？

这是我的composer.json：

{
    "autoload": {
        "psr-0": {
            "MyApp": "src"
        }
    },
    "require": {
        "cboden/ratchet": "0.3.*",
        "react/zmq": "0.2.*|0.3.*"
    }
}

Push_server.php（包括自动加载文件）：

<?php
    require dirname(__DIR__) . '/vendor/autoload.php';

    $loop   = React\EventLoop\Factory::create();
    $pusher = new MyApp\Pusher;

    // Listen for the web server to make a ZeroMQ push after an ajax request
    $context = new React\ZMQ\Context($loop);
    $pull = $context->getSocket(ZMQ::SOCKET_PULL);
    $pull->bind('tcp://127.0.0.1:5555'); // Binding to 127.0.0.1 means the only client that can connect is itself
    $pull->on('message', array($pusher, 'onBlogEntry'));

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

    $loop->run();

Answer 1

您应该检查自动加载文件，如果您使用L aravel ，请查看文件夹： vendor / composer 应该有一个名为<的文件em> autoload_classmap 并找到这一行：

'Ratchet\\Wamp\\WampServerInterface' => $vendorDir . '/cboden/ratchet/src/Ratchet/Wamp/WampServerInterface.php',

如果文件中没有包含任何与Ratchet相关的内容，请从命令行中composer dump-autoload

Answer 2

在项目的根目录下删除composer.lock并创建此composer.json文件

{
    "autoload": {
        "psr-4": {
            "MyApp\\": "src"
        }
    },
    "require": {
        "cboden/ratchet": "^0.4.2",
        "react/zmq": "0.4.0"
    }
}

在终端cd上到根文件夹，然后输入：

composer install

那将为您提供正确的组件。

您的文件夹应如下所示： bin / push-server.php src / Pusher.php

从项目根文件夹中运行“ php bin / push-server.php”终端命令。

如果有人发现我的建议有用，请给我评分，因为stackoverflow阻止了我提出问题。我会很感激的。

谢谢！
