código de resposta 0 obtendo JSON de um site
Eu estou tendo um problema com o código abaixo, sempre que eu iria tentar solicitar os dados JSON do site, eu sempre receber de volta um código de resposta 0. Alguém sabe por quê? Se eu fosse para o site eu iria obter os dados apenas inserindo as informações de login corretas.
