How to parse data from POST request

I have a getter context : HTTP::Server::Context and a login form.
Now I want to parse data from context.request.body to get username and password which user input.

The response's content type: application/x-www-form-urlencoded

HTTP::Params.parse is what you're looking for:

# Based on the sample code in https://crystal-lang.org/ home
require "http/server"

server = HTTP::Server.new(8080) do |context|
  context.response.content_type = "text/plain"
  if body = context.request.body
    params = HTTP::Params.parse(body)
    context.response.print "Hello #{params["user"]? || "Anonymous"}!"
  else
    context.response.print "You didn't POST any data :("
  end
end

puts "Listening on http://127.0.0.1:8080"
server.listen
