You need to modify this part of your code:
post("/sign-in", (req, res) -> {
Map<String, String> model = new HashMap<>();
String username = req.queryParams("username");
res.cookie("username", username);
model.put("username", username);
return new ModelAndView(model, "sign-in.hbs");
}, new HandlebarsTemplateEngine());
The main point is to make this post /sign-in to be redirected to / (or main page) while retrieving String username from the req.cookie.
Also you do not need to render things, thus you don't need the HandlebarTemplateEngine since you will just redirect it to / page which already has HandlebarTemplateEngine renderer. Thus, all related to modelling and preparing for rendering also can be deleted:
- Map<String, String> model
- model.put
-
return new ModelAndView This how the code should looks like:
post("/sign-in", (req, res) -> { String username = req.cookie("username"); res.cookie("username", username);// put username to cookie res.redirect("/"); return null });
I hope this can help. Please try it
