RawPathInfo provides handlers access to the raw, unparsed path information the WAI request.

If you wish to get the path segments, you can either use the PathInfo combinator in Servant.API.PathInfo or parse it yourself with Network.HTTP.Types.decodePathSegments

Example:

import Data.ByteString (ByteString)
import Control.Monad.IO.Class (liftIO)
import Servant
import ServantExtras.RawPathInfo

type MyAPI = "my-path-info-endpoint"
           :> RawPathInfo
           :> Get '[JSON] NoContent

myServer :: Server MyAPI
myServer = queryEndpointHandler
 where
   queryEndpointHandler :: ByteString -> Handler NoContent
   queryEndpointHandler rawPath = do
     case rawPath of
      "/my-path-info-endpoint" -> do
        liftIO $ print "Servant routed us to the right place!"
        pure NoContent
      _ -> do
        liftIO $ print "My example has a bug!"
        throwError err400 { errBody = "Patches accepted!" }
