ここにPHPスクリプトがあります
<?php
$username = "zaigi";
$password = "1111";
$androidUserName = json_decode($_POST['username']);
$androidPassword = json_decode($_POST['password']);
if($androidUserName == $username && $androidPassword == $password){
$response = "Correct";
}else{
$response = "Error";
}
echo json_encode($response);
?>
