問題描述

我正在嘗試在 Symfony2 中實現 websockets，

I'm trying to implement websockets in Symfony2,

我發現這個 http://socketo.me/ 看起來不錯.

I found this http://socketo.me/ which seems pretty good.

我在 Symfony 中嘗試了它并且它有效，這只是使用 telnet 的一個簡單調用.但我不知道如何將其集成到 Symfony 中.

I try it out of Symfony and it works, this was just a simple call using telnet. But I don't know how to integrate this in Symfony.

我想我必須創建一個服務，但我真的不知道哪種服務以及如何從客戶端調用它

I think I have to create a service but I don't know realy which kind of service and how to call it from the client

感謝您的幫助.

推薦答案

首先你應該創建一個服務.如果您想注入實體管理器和其他依賴項，請在此處進行.

First you should create a service. If you want to inject your entity manager and other dependencies, do it there.

在 src/MyApp/MyBundle/Resources/config/services.yml 中:

In src/MyApp/MyBundle/Resources/config/services.yml:

services:
    chat:
        class: MyAppMyBundleChat
        arguments: 
            - @doctrine.orm.default_entity_manager

在 src/MyApp/MyBundle/Chat.php 中:

And in src/MyApp/MyBundle/Chat.php:

class Chat implements MessageComponentInterface {
    /**
     * @var DoctrineORMEntityManager
     */
    protected $em;
    /**
     * Constructor
     *
     * @param DoctrineORMEntityManager $em
     */
    public function __construct($em)
    {
        $this->em = $em;
    }
    // onOpen, onMessage, onClose, onError ...

接下來，執行控制臺命令來運行服務器.

Next, make a console command to run the server.

在 src/MyApp/MyBundle/Command/ServerCommand.php 中

In src/MyApp/MyBundle/Command/ServerCommand.php

use SymfonyBundleFrameworkBundleCommandContainerAwareCommand;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use RatchetServerIoServer;

class ServerCommand extends ContainerAwareCommand
{
    protected function configure()
    {
        $this
            ->setName('chat:server')
            ->setDescription('Start the Chat server');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $chat = $this->getContainer()->get('chat');
        $server = IoServer::factory($chat, 8080);
        $server->run();
    }
}

現在您有一個帶有依賴注入的 Chat 類，您可以將服務器作為控制臺命令運行.希望這會有所幫助！

Now you have a Chat class with dependency injections, and you can run the server as a console command. Hope this helps!
