código de respuesta 0 obteniendo JSON de un sitio web
Estoy teniendo un problema con el siguiente código, siempre que intentaría solicitar los datos JSON del sitio web, siempre obtendría un código de respuesta 0. ¿Alguien sabe por qué? Si tuviera que ir al sitio web, obtendría los datos con solo ingresar la información de inicio de sesión correcta.
