emitLog method

@override Future<void> emitLog(LogEvent event)

Performs the actual delivery of event to the transport's destination.

Called only when event.level >= this.level. Implementations must not throw; swallow or handle errors internally.

Implementation

@override
Future<void> emitLog(LogEvent event) async {
  try {
    final payload = serializer != null
        ? serializer!(event)
        : _defaultPayload(event);
    final uri = Uri.parse(endpoint);
    final client = HttpClient();
    if (proxy != null) {
      client.findProxy = (_) => 'PROXY $proxy;';
    }
    final request = await client.postUrl(uri);
    headers.forEach((k, v) => request.headers.set(k, v));
    request.headers.set('Content-Type', 'application/json');
    request.add(utf8.encode(jsonEncode(payload)));
    if (timeout != null) {
      final response = await request.close().timeout(
        Duration(milliseconds: timeout!),
      );
      await response.drain<void>();
    } else {
      final response = await request.close();
      await response.drain<void>();
    }
    client.close();
  } catch (_) {
    // Swallow transport errors to avoid disrupting the application.
  }
}
