Getting Login Credentials from Flutter APP Using PHP

Question

I'm trying to get the email and password from a flutter app using PHP but for some reason i'm getting null results, any idea how I can do it?

Seems that the PHP code actually works fine if the username and password are in the URL itself, however, does not work if I try to follow the example below.

PHP:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET');

echo $email = $_GET["email"];
echo $password = $_GET["password"];

Flutter:

Future<void> login(String email, String password) async {

     final url = Uri.parse(
         'example.com/file.php');
     final response = await http.post(
       url,
       body: json.encode(
         {
           'email': email,
           'password': password,
         },
       ),
     );
  }

I'm not familiar with Flutter, put it seems you are posting (POST) your vars. So it should mabe be:

echo $email = $_POST["email"];
echo $password = $_POST["password"];

Or it is in the body of the request:

$body = file_get_contents('php://input');
$payload = json_decode($body,true);
$email = $payload['email'];
$password = $payload['password'];

Already tried, unfortunately I'm still getting null resuts :( – ramenknight Apr 19 '22 at 19:28
If Flutter puts the vars in the body you can retreive them as shown here: https://stackoverflow.com/questions/8945879/how-to-get-body-of-a-post-in-php – Onki Hara Apr 19 '22 at 19:31
And how to access the email and password inside the body? – ramenknight Apr 19 '22 at 19:34
I edited my answer, but be aware of the fact that I didn't test it. – Onki Hara Apr 19 '22 at 20:02
