在Symfony中处理WebSocket错误,你需要关注以下几个方面:
try-catch
语句。例如:public function onMessage(ConnectionInterface $from, $msg)
{
try {
// 处理WebSocket消息的逻辑
} catch (\Exception $e) {
// 处理异常,例如记录日志或发送错误响应
$this->logger->error('Error processing message: ' . $e->getMessage());
$response = new TextMessage('An error occurred while processing your request.');
$from->send($response);
}
}
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
public function __construct()
{
$this->logger = new Logger('websocket_error');
$handler = new StreamHandler(sys_get_temp_dir() . '/websocket_errors.log', Logger::ERROR);
$this->logger->pushHandler($handler);
}
TextMessage
类来创建一个包含错误信息的文本消息。例如:$response = new TextMessage('An error occurred while processing your request.');
$from->send($response);
ExceptionListener
或ErrorListener
来捕获特定的HTTP异常,并返回自定义的错误响应。例如:use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
public function onKernelException(ExceptionEvent $event)
{
if ($event->getException() instanceof NotFoundHttpException) {
$response = new TextMessage('The requested resource was not found.');
$event->setResponse(new Response($response->getContent(), $response->getStatusCode()));
}
}
public function handle($request, Closure $next)
{
try {
return $next($request);
} catch (\Exception $e) {
// 处理异常,例如记录日志或发送错误响应
$this->logger->error('Error processing request: ' . $e->getMessage());
$response = new TextMessage('An error occurred while processing your request.');
return new Response($response->getContent(), $response->getStatusCode());
}
}
通过以上方法,你可以在Symfony中有效地处理WebSocket错误。
