func HTTPRequest(host, page, dictionary_data):

Hi. My function is in a Singleton class named Game. And I’m calling this func like this:

	
func button_down_login():
	var host = "http://www.rabidstreets.test"
	var page = "/en/game/login"
	var dictionary_data = {}
	dictionary_data['username'] = lineEditUsername.get_text()
	dictionary_data['password'] = lineEditPassword.get_text()
	var data = Game.HTTPRequest(host, page, dictionary_data)
	print(data)

And it prints nothing. Can you help me?

Just fix this part as:

var body = {}
body["username"] = "user"
body = JSON.print(body)
err = http.request(HTTPClient.METHOD_POST, page, headers, body)
