Magento API : How to load customer session by ID - php

Question

I'm working on magento module to log in customer with API.
I can log in customer and get frontend sessionId,
but when I want to load session with this sessionId to check if the customer is already logged in I can't.
Here the API function I used:
public function login($email,$password,$storecode){
$result = array();
$result['code'] = '';
$result['messages'] = '';
try{
$session = Mage::getSingleton('customers/session');
$storemodel = Mage::getModel('core/store')->load($storecode);
$store_id = $storemodel->getId();
$websiteId = $storemodel->getWebsiteId();
if($session->loginByApi($email, $password,$websiteId)){
$result['code'] = 'SUCCESS';
$result['sessionId'] = $session->getSessionId();
$customer = $session->getCustomer();
$result['customer']= array(
'customerid' => $customer->getId(),
'firstname' => $customer->getFirstname(),
'lastname' => $customer->getLastname(),
);
}
} catch (Mage_Core_Exception $e) {
$result['code'] = 'ERRORS';
$result['messages'] = $e->getMessage();
}
return $result;
}
public function isloggedin($customerId,$customersessionId ,$storecode){
if(!isset($storecode)){
$storecode = 'default';
}
Mage::app($storecode, 'store');
$core_session = Mage::getSingleton('core/session', array('name'=>'frontend'));
if($customersessionId != null){
$core_session->setSessionId($customersessionId);
$core_session->start('frontend');
}
$session = Mage::getSingleton('customer/session', array('name'=>'frontend'));
$customer = Mage::getModel('customer/customer')->load($customerId);
$session->setCustomer($customer);
if($session->isLoggedIn()){
$session->setCustomerAsLoggedIn($customer);
$result['sessionId'] = $session->getSessionId();
}else{
$result['logged'] = false;
}
return $result;
}
Anyone have an idea?

Not sure if this helps too much, but this code:
Mage::app('2', 'store');
$s = Mage::getSingleton('customer/session', array('name'=>'frontend'));
$c = Mage::getModel('customer/customer')->load(1);
$s->setCustomer($c);
if($s->isLoggedIn()){
echo $c->getName()." is logged in, session: ".$s->getSessionId().PHP_EOL;
} else {
echo "not logged in".PHP_EOL;
}
Did seem to work for me:
John Smith is logged in, session: d3rcgvd56md4u3cfctcvnt2ou6

If you have the Session ID, you can get at the data with the following call to the core session singleton:
$sessId = 'sn1q4ndvr1kieumsmplhd39n83';
$sess = Mage::getSingleton('core/session', array( 'value' => $sessId ));
That will retrieve the session for any user, logged-in or not. From there you can determine whether the session belongs to a customer with a check for the customer object:
$sessionCustomerId = $sess->getCustomer()->getId();
if ( $sessionCustomerId ) {
// yay, they are a customer!
echo $sessionCustomerId;
}
Hope that helps.
Edit:
You can get the session id from the core session (in a chicken-and-egg style) using Mage::getSingleton('core/session')->getEncryptedSessionId()
