How do I make a call to that URL that captures the User ID, using Magento customer Token in magento 2 rest API?

How Magento 2 makes calls in-between for the APIs ?

How magento 2 make calls in-between for the APIs ?

Magento gets the customer data with passing anything except token value in API call.

In between magento calls some API related controllers for the same

vendor/magento/module-customer/etc/webapi.xml

<route url="/V1/customers/me" method="GET">

        <service class="MagentoCustomerApiCustomerRepositoryInterface" method="getById"/>

        <resources>

            <resource ref="self"/>

        </resources>

        <data>

            <parameter name="customerId" force="true">%customer_id%</parameter>

        </data>

 </route>

in this API call magento get customer data based on token.

Based on API url url="/V1/customers/me" magento calls function from

Magento calls In-between call of dispatch function.

vendor/magento/module-webapi/Controller/Rest.php

 public function dispatch(MagentoFrameworkAppRequestInterface $request)

 {

     /** In between code **/

     // In the same file

     $this->processApiRequest();



 }

 protected function processApiRequest()

 {

      $inputParams = $this->getInputParamsResolver()->resolve();

 }

And this resolve() function calls override() function

vendor/magento/module-webapi/Controller/Rest/InputParamsResolver.php

 public function resolve()

 {

      $inputData = $this->paramsOverrider->override($inputData, $route->getParameters());

 }

and overide() function calls getOverriddenValue() function

vendor/magento/module-webapi/Controller/Rest/ParamsOverrider.php

 public function override(array $inputData, array $parameters)

 {

      $value = $this->paramOverriders[$paramValue]->getOverriddenValue();

 }

getOverriddenValue() calls ParamOverriderInterface

vendor/magento/framework/Webapi/Rest/Request/ParamOverriderInterface.php

• To Override parameter values


• Parameters in the webapi.xml can be forced. This ensures that on
  specific routes, a specific value is always used.


• For instance, if there is a ".../me/..." route, the route should use
  only user information specific to the


• currently logged in user. More specifically, if there was a
  "/customers/me/addresses" route, the service method


• invoked could have a signature of "getAddresses($customerId)", but in
  the webapi.xml, the $customerId parameter


• would be forced to be the customer id of the current authenticated
  user.


• The forced override parameter configuration is in the webapi.

   <data>

     <parameter name="customer.id" force="true">%customer_id%</parameter>

   </data>

and for business logic of this function is in file -

vendor/magento/module-webapi/Controller/Rest/ParamOverriderCustomerId.php

   /**

    * {@inheritDoc}

    */

   public function getOverriddenValue()

   {

       if ($this->userContext->getUserType() === UserContextInterface::USER_TYPE_CUSTOMER) {

           return $this->userContext->getUserId();

   }

   return null;

   }

So this is how Magento get Customer Id between API calls !!

Another solution

$ch = curl_init('dev.magento2.com/rest/V1/customers/me');

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(

    'Content-Type: application/json'

));

curl_setopt($ch, CURLOPT_COOKIE, 'PHPSESSID=' . $_COOKIE['PHPSESSID']);

curl_setopt($ch, CURLOPT_TIMEOUT, 5);

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);



//execute post

$result = curl_exec($ch);



//close connection

curl_close($ch);



$json = json_decode($result);

echo $json->id;
