Cédrick Side note: perfect late binding information for the lecture I do tomorrow with Pharo where I show students client server interaction with ZnClient, ZnServer … ^_^ > Le 7 nov. 2018 à 17:36, Sven Van Caekenberghe <s...@stfx.eu> a écrit : > > Hi, > > I added a new convenience method to Zinc HTTP Components: > ZnClient>>forJsonREST.
