在 Moodle 中自动验证用户身份

Question

I am trying to automatically authenticate a user in Moodle but having trouble using authenticate_user_login in Moodle 3.8.3. I have tested the below code but I get the following error:

Exception - Argument 1 passed to core\session\manager::login_user() must be an instance of stdClass, boolean given, called in [dirroot]/lib/moodlelib.php on line 4632

Appreciate your help.

<?php
require('config.php');
$name="myusername";
$password="mypassword";
$dashboard = $CFG->wwwroot;
$user = authenticate_user_login($name, $password);
if(complete_user_login($user))
{
echo "login";
}
else
{
   echo "not login";
}



?>

I've seen this message during Moodle SSO work if the $password value passed to authenticate_user does not match the user's actual password. In that case, $user returns false, which is then passed to complete_user_login and eventually to login_user , triggering the error. After updating the password to match, all worked as expected.

Guessing the same result would occur if $name does not exist or anything else that would return false from authenticate_user_login , although haven't had chance to test other scenarios.
