httpResponseHandler function

dynamic httpResponseHandler(dynamic payload, HttpRequest request)

Implementation

dynamic httpResponseHandler(
  dynamic payload,
  HttpRequest request,
) {
  /// Websocket handler will return websocket payload
  /// and in this case we need to remain the connection open for
  /// websocket communication. So there is no `res.close()` required.
  if (payload is WebSocket) {
    return;
  }

  /// If there is responseHandler set, handle responseHandler
  /// before DoxResponse process. The responseHandler will return
  /// DoxResponse to process
  ResponseHandlerInterface? customResponseHandler = DoxServer().responseHandler;
  if (customResponseHandler != null) {
    DoxResponse doxResponse = customResponseHandler
        .handle(payload is DoxResponse ? payload : DoxResponse(payload));
    payload = doxResponse;
  }

  /// If payload is DoxResponse, DoxResponse have process function
  /// which will set header and status code in the response
  /// and will pass payload/content to `responseDataHandler` function.
  if (payload is DoxResponse) {
    payload.process(request);
    return;
  }
}
