Method: HTTPTools::Parser#env

Defined in:
lib/http_tools/parser.rb

#env ⇒ Object

:call-seq: parser.env -> hash or nil

Returns a Rack compatible environment hash. Will return nil if called before headers are complete.

“SERVER_NAME” and “SERVER_PORT” are only supplied if they can be determined from the request (eg, they are present in the “Host” header).

“rack.input” is only supplied if #env is called after parsing the request has finsished, and no listener is set for the stream event

If not supplied, you must ensure “SERVER_NAME”, “SERVER_PORT”, and “rack.input” are present to make the environment hash fully Rack compliant
