如何从另一个控制器类获取值

I have two controller classes AuthenticationController and RegisterUrlController.

I would want to call a function in AuthenticationController class called authorization to return a value and use the value in the RegisterUrlController class and function registerUrl as the ACCESS_TOKEN variable on the CURLOPT_HTTPHEADER array value.

See sample code;

<?php

namespace App\Http\Controllers\C2B;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;


class RegisterUrlController extends Controller
{

    public function registerUrl(Request $request)
    {

        $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, $url);
        // The ACCESS_TOKEN should be passed from the other class 
            curl_setopt($curl, CURLOPT_HTTPHEADER, 
        array('Content-Type:application/json','Authorization:Bearer $ACCESS_TOKEN')
             ); 

            $curl_post_data = array(
              //Fill in the request parameters with valid values
              'ShortCode' => $request->ShortCode,
              'ResponseType' => 'ResponseType',
              'ConfirmationURL' => $request->confirmation_url,
              'ValidationURL' => $request->validation_url
            );

            $data_string = json_encode($curl_post_data);

            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_POST, true);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data_string);

            $curl_response = curl_exec($curl);
            print_r($curl_response);

            echo $curl_response;


            curl_close($curl);

    }
}

The class generating the ACCESS_TOKEN above is below.

How do I pass this return value to be the ACCESS_TOKEN value on the array header above?

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class AuthenticationController extends Controller
{

    public function __construct()
    {
        $this->middleware('guest');
    }


    public function authorization()
    {

            $curl = curl_init();

            curl_setopt($curl, CURLOPT_URL, $url);

            $credentials = base64_encode('statum:ub435!');
            curl_setopt($curl, CURLOPT_HTTPHEADER, array('Authorization: Basic '.$credentials)); //setting a custom header
            curl_setopt($curl, CURLOPT_HEADER, true);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

            $curl_response = curl_exec($curl);

            return json_decode($curl_response); //this is the response I need passed over to the other class


   }
}

Question, how do I go about getting values from another controller?

Anyone?

You can use few ways to do this

1. Extends Class

2. Create Class Object

3. Use Namespace

4. Make Authentication Service and then call it
