vendor/hybridauth/hybridauth/

Answer 1

This file already included in codeigniter core file. dont need to incluse again in your class file

include 'vendor/autoload.php';  

Within your function

public function test_auth() {
  // Before code
    $config = [
        'callback' => 'https://example.com/path/to/script.php',
        'keys' => [ 'key' => 'your-twitter-consumer-key', 'secret' => 'your-twitter-consumer-secret' ]
    ];

    try {
        $twitter = new Hybridauth\Provider\Twitter($config);

        $twitter->authenticate();

        $accessToken = $twitter->getAccessToken();
        $userProfile = $twitter->getUserProfile();
        $apiResponse = $twitter->apiRequest( 'statuses/home_timeline.json' );
    }
    catch(\Exception $e){
        echo 'Oops, we ran into an issue! ' . $e->getMessage();
    }

        }

Check the usage from the package README

Answer 2

I have also faced the same issue. When I install a package using the composer on the root location then it was still saying that the third party class not found. So here is my solution. First of all, I change the "composer_autoload" config to TRUE.

$config['composer_autoload'] = TRUE;

By default after change the above configuration Codeigniter looking vendor/autoload file under APPPATH(application folder) which is incorrect. So I change the constant to FCPATH(root path) because the root is the correct path to install the third-party packages using the composer.

change from System/core/Codeigniter.php:165

if ($composer_autoload === TRUE)
{
    file_exists(APPPATH.'vendor/autoload.php')
        ? require_once(APPPATH.'vendor/autoload.php')
        : log_message('error', '$config[\'composer_autoload\'] is set to TRUE but '.APPPATH.'vendor/autoload.php was not found.');
}

to

if ($composer_autoload === TRUE)
{
    file_exists(FCPATH.'vendor/autoload.php')
        ? require_once(FCPATH.'vendor/autoload.php')
        : log_message('error', '$config[\'composer_autoload\'] is set to TRUE but '.FCPATH.'vendor/autoload.php was not found.');
}

and finally, run

composer dumpautoload

in case if still not working. Happy coding!!!
