getResponseHeader function

String? getResponseHeader(
  1. H4Event event,
  2. String header
)

Retrieves the value of a specific header in the HTTP response from an H4Event instance.

The getResponseHeader function is used to extract the value of a specified header from the HTTP response of an H4Event object. The H4Event object is expected to have a node property that contains the HTTP request, and the node["value"] property is assumed to represent the incoming HTTP request.

Parameters:

  • event: An H4Event instance containing the HTTP request.
  • header: The name of the header to retrieve.

Returns: The value of the specified header, or null if the header is not found or the response is null.

Implementation

String? getResponseHeader(H4Event event, String header) {
  return event.node["value"]?.response.headers.value(header);
}
