http.server - 不支持的方法（'POST'）

Question

So I have created a website, when the user tries to fill out the login form (username and password), the following error message is displayed:

Error response
Error code: 501

Message: Unsupported method ('POST').

Error code explanation: HTTPStatus.NOT_IMPLEMENTED - Server does not support this operation.

For the server im using Python 3 http.server. To start the server i have a batch file containing the following code:

python -m http.server 80

I'm looking for a way to receive the login credentials the user submitted, and store them in a text file (.txt).

After doing some research I got the impression I need to create a PHP script, i have no idea how to do this. here is my attempt at it:

<?php
$username = htmlspecialchars($_POST['username']);
$password = htmlspecialchars($_POST['password']);

echo $username, ' ', $password;
?>

It seems like you don't have POST support on your webserver. Try using GET instead.

<?php
$username = htmlspecialchars($_GET['username']);
$password = htmlspecialchars($_GET['password']);

echo $username, ' ', $password;
?>

Although the code you wrote will simply print the user details, not store them. I would however recommend enabling POST and using it instead.

Edit: As pointed out by another user GET is not secure and should not be used for passwords. This method will work but I would recommended not using it and instead looking for a way to implement POST into your webserver.

I would also not recommend storing the passwords in a text file. PHP comes with built in methods for encrypting passwords. I would recommend reading about how to implement hashing such as Argon2:
