How can I get request headers with python hug

Question

In a function annotated as a hug api call, how can I get the headers for that call?

Answer 1

The easy, normal and fastest way: Hug provides request and body (POST) if they are present as arguments (https://github.com/timothycrosley/hug/issues/120).

@hug.get('/headers', output=hug.output_format.json)
def headers(request, header_name: hug.types.text=None):
    if header_name is None:
        return request.headers
    return {header_name: request.get_header(header_name)}
