我在symfony 2上使用symfony 2和ratchet和memcache聊天項目ratchet與symfony一起工作良好，我在官方網站上的「hello world」應用程序上測試它 問題是，當我跑這條線嘗試從名稱空間加載類「MyApp」
new Chat(new MyApp(), $this->getContainer()),
我得到這個錯誤
Attempted to load class "MyApp" from namespace
我的命令行代碼
<?php
// myapplication/src/sandboxBundle/Command/SocketCommand.php
// Change the namespace according to your bundle
namespace check\roomsBundle\Command;
use Ratchet\Session\SessionProvider;
use Symfony\Component\HttpFoundation\Session\Storage\Handler;
use Doctrine\Common\Cache\MemcacheCache;
use Ratchet\App;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\HttpFoundation\Session\Storage\Handler\MemcacheSessionHandler;
use Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage;
// Include ratchet libs
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
// Change the namespace according to your bundle
use check\roomsBundle\Sockets\Chat;
use Doctrine\ORM\EntityManager;
use Symfony\Component\HttpFoundation\Session\Session;
class WsServerCommand extends ContainerAwareCommand
{
protected function configure()
{
$this->setName('sockets:start-chat')
// the short description shown while running "php bin/console list"
->setHelp("Starts the chat socket demo")
// the full command description shown when running the command with
->setDescription('Starts the chat socket demo')
; }
protected function execute(InputInterface $input, OutputInterface $output)
{
$output->writeln([
'Chat socket',// A line
'============',// Another line
'Starting chat, open your browser.',// Empty line
]);
$memcache = new \Memcache;
$memcache->connect('localhost', 11211);
$session = new SessionProvider(
new Chat(new MyApp(), $this->getContainer()),
new Handler\MemcacheSessionHandler($memcache)
);
$server = new App('localhost');
$server->route('/sessDemo', $session);
$server->run();
}
}
