Get Customer Name if its logged in otherwise return message in API Magento 2

Question

I am trying to get the customer's name by POST Method API if it's logged in but when I hit the link the postman, returns the Customer's Name even if it's not logged in. Please take a look

CODE:

<?php 
namespace Vendor\Login\Model\Customer;

use Magento\Authorization\Model\UserContextInterface;
use Magento\Customer\Api\AccountManagementInterface;
use Magento\Customer\Block\Account\AuthorizationLink;
use Magento\Customer\Model\Session;
use Magento\Customer\Model\Url;
use Magento\Framework\App\Action\Context;
use Magento\Framework\Controller\Result\JsonFactory;
use Magento\Framework\Exception\AuthenticationException;
use Magento\Framework\Exception\LocalizedException;

//use Vendor\Login\Controller\Index\ApiController;

/**
 * Implementing the logic
 */
class Extra
{
    protected AuthorizationLink $ath;
    protected UserContextInterface $userContext;
    /**
     * @var Session
     */
    protected Session $customerSession;
    /**
     * @var AccountManagementInterface
     */
    protected AccountManagementInterface $customerAccountManagement;
    /**
     * @var Url
     */
    protected Url $customerUrl;
    protected JsonFactory $jsonFactory;

    /**
     * @param Context $context
     * @param Url $customerUrl
     * @param AccountManagementInterface $customerAccountManagement
     * @param Session $customerSession
     * @param JsonFactory $jsonFactory
     * @param UserContextInterface $userContext
     * @param AuthorizationLink $ath
     */
    public function __construct(
        Context $context,
        Url $customerUrl,
        AccountManagementInterface $customerAccountManagement,
        Session $customerSession,
        JsonFactory $jsonFactory,
        UserContextInterface $userContext,
        AuthorizationLink $ath

    ) {
        parent::__construct($context);
        $this->customerUrl = $customerUrl;
        $this->customerAccountManagement = $customerAccountManagement;
        $this->customerSession = $customerSession;
        $this->jsonFactory = $jsonFactory;
        $this->userContext = $userContext;
        $this->ath = $ath;

    }

    /**
     * @param string $email
     * @param string $password
     * @return array[]
     * @throws LocalizedException
     */
    public function login(string $email, string $password): array
    {
        $validate = array();
        $login = array();
        $result = $this->jsonFactory->create();
        $customerinfo = array();

        if ($email) {
            $login['username'] = $email;
        }
        if ($password) {
            $login['password'] = $password;
        }

        try {

            if (($email == null) || ($password == null)) {
                $message = __('Invalid Username');

                return array($message);
            } 

            else {


                $customer = $this->customerAccountManagement->authenticate($email, $password);

                $this->customerSession->setCustomerDataAsLoggedIn($customer);

                $this->customerSession->regenerateId();

                if (!$this->ath->isLoggedIn()) {
                    $customer_data = $this->customerSession->getCustomer()->getData();

                    $customerinfo = array(
                        "name" => $customer_data['firstname'] . $customer_data['lastname']
                    );

                    return array($customerinfo);

                }
                else {

                    $error = __('Error');
                    return array($error);
                }
            }

        } 
        catch (AuthenticationException $e) {
            $new = __('You are not logged in');
            return array($new);
        }
    }

}

Answer 1

You can use it like this. This code will return customer tokens if logged in so hopefully, this will help a lot.

<?php

$userDataArr = ["username" => "[email protected]", "password" => "654321"];
$ch = curl_init("http://example.com/rest/V1/integration/customer/token");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($userDataArr));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Content-Lenght: " . strlen(json_encode($userDataArr))));

$token = curl_exec($ch);

//Get customer info
$ch = curl_init("http://example.com/rest/V1/customers/me");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET"); // Get method
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token)));

$result = curl_exec($ch);

$result = json_decode($result, 1);
echo '<pre>';print_r($result);

Answer 2

First of all you need to create a new POST request in POSTMAN

Using below url

http://localhost/magento2/rest/V1/integration/customer/token?username=customer_email_id&password=customer_password

Change customer_email_id in url with the customer's email you want to get the name

And Change customer_password in url with the customer's password and also change http://localhost/magento2 with your project url

It will return a token, you need to copy that token

NEXT STEP

Now open your custom request where you are getting customer name

Go to Authorization Tab and choose Bearer Token

Now copy the token generated in previous request and page in Bearer Token in your request

It will verify the customer token and print your output

Hope it will work for you!

Please let me know if you get any issue.
