Parameters: sink (callable) – A callable taking the form func(req, resp). prefix (str) – A regex string, typically starting with ‘/’, which will trigger the sink if it matches the path portion of the request’s in query string parameters (default False). auto_parse_form_urlencoded Set to True in order to automatically consume the request stream and merge the results into the request’s query string params when relative_uri str – The path + query string portion of the full URI. path str – Path portion of the request URL (not including query string). query_string str – Query string portion of the request URL, without

Parameters: sink (callable) – A callable taking the form func(req, resp). prefix (str) – A regex string, typically starting with ‘/’, which will trigger the sink if it matches the path portion of the request’s for configuring certain Request behaviors. keep_blank_qs_values bool – Set to True to keep query string fields even if they do not have a value (default False). For comma-separated values, this option order to automatically consume the request stream and merge the results into the request’s query string params when the request’s content type is application/x-www-form-urlencoded (default False).
