Oauth tokens storing in mysql database does not work but works fine when using sessions

Question

I'm trying to create app with 4shared API but to use it I need to authorize in 4shared using Oauth. The problem is that when I'm using sessions to store oauth_token everything works fine, but when Im trying to store tokens in Mysql database I'm getting error:

OAuthException:  No server with consumer_key "MY_CONSUMER_KEY" has been registered (for this user)object(OAuthException2)#3 (7) {

I have created proper mysql database and imported mysql.sql file into it from Oauth's store folder. Also If I'm not using 'conn' as an Option it does not connect to database at all, but I'm able to connect to DB with 'conn' option.

Here is my code:

include_once "library/OAuthStore.php";
include_once "library/OAuthRequester.php";

define("FOURSHARED_CONSUMER_KEY", "MY_CONSUMER_KEY");
define("FOURSHARED_CONSUMER_SECRET", "MY_SECRET_KEY");
define("FOURSHARED_OAUTH_HOST", "https://api.4shared.com");
define("FOURSHARED_OAUTH_HOST_SEARCH", "https://search.4shared.com");
define("FOURSHARED_REQUEST_TOKEN_URL", FOURSHARED_OAUTH_HOST . "/v1_2/oauth/initiate");
define("FOURSHARED_AUTHORIZE_URL", FOURSHARED_OAUTH_HOST . "/v1_2/oauth/authorize");
define("FOURSHARED_ACCESS_TOKEN_URL", FOURSHARED_OAUTH_HOST . "/v1_2/oauth/token");
define('OAUTH_TMP_DIR', function_exists('sys_get_temp_dir') ? sys_get_temp_dir() : realpath($_ENV["TMP"]));


define("FOURSHARED_OAUTH_CALLBACK", "https://example.com/4shared/index.php");    

//  Inicia o OAuthStore
$options = array(
    'consumer_key' => FOURSHARED_CONSUMER_KEY, 
    'consumer_secret' => FOURSHARED_CONSUMER_SECRET,
    'server_uri' => FOURSHARED_OAUTH_HOST,
    'request_token_uri' => FOURSHARED_REQUEST_TOKEN_URL,
    'authorize_uri' => FOURSHARED_AUTHORIZE_URL,
    'access_token_uri' => FOURSHARED_ACCESS_TOKEN_URL,
    //'server' => 'localhost',
    //'username' => 'oauth',
    //'password' => 'password',
    //'database' => 'oauth',
    'conn' => new mysqli('localhost','oauth','password','oauth')
);

// Store token in database or sessions
// Choose a database.
OAuthStore::instance("MySQLi", $options);

try
{
    //  Step 1: If there is not an OAuth token yet, we need one.
    if (empty($_GET["oauth_token"]))
    {
        $getAuthTokenParams = array(
            'scope' => FOURSHARED_OAUTH_HOST . '/v1_2',
            'xoauth_displayname' => 'Oauth 4Shared',
            'oauth_callback' => FOURSHARED_OAUTH_CALLBACK
        );

        // Request a request token
        $tokenResultParams = OAuthRequester::requestRequestToken(FOURSHARED_CONSUMER_KEY, 0, $getAuthTokenParams);

        // Redirects to the authorization page. Here the user will give you permissions the first time and then be redirected back to your site.
        header("Location: " . FOURSHARED_AUTHORIZE_URL . "?oauth_token=" . $tokenResultParams['token']);
    }
    else {
        //  Step 2: Request an access token
        $oauthToken = $_GET["oauth_token"];
        $tokenResultParams = $_GET;

        try {
            OAuthRequester::requestAccessToken(FOURSHARED_CONSUMER_KEY, $oauthToken, 0, 'POST', $_GET);
        }
        catch (OAuthException2 $e)
        {
            var_dump($e);
            return;
        }
        // We will request user information
        $request = new OAuthRequester(FOURSHARED_OAUTH_HOST_SEARCH . '/v1_2/files', 'GET', $tokenResultParams);
        $result = $request->doRequest(0);
        if ($result['code'] == 200) {
            // Convert string to json object
            $files_result = json_decode($result['body']);

            // Print the screen on the e-mail;
            print_r($files_result);
        }
        else {
            echo 'Error';
        }
    }
}
catch(OAuthException2 $e) {
    echo "OAuthException:  " . $e->getMessage();
    var_dump($e);

}

Everything works fine when im changing OAuthStore::instance("MySQLi", $options); to OAuthStore::instance("sessions", $options);

Im also linking to a file with wich I created the database (this is file provided by oauth): https://pastebin.com/2eb0aTbL

Hi I think you are creating instance not properly.

can you check below link for a various example of Oauth Instance Creation?

php-oauthstore-instance-method-examples

function get_db_options()
{
    return array('server' => DB_HOST, 'username' => DB_USERNAME, 'password' => DB_PASSWORD, 'database' => DB_NAME);
}

$oauth = OAuthStore::instance('MySQL', get_db_options());

For Mysqli use below code to connect

$con = mysqli_connect("localhost","my_user","my_password","my_db");

OAuthStore::instance('MySQLi', array('conn' => $con, 'table_prefix' => UserConfig::$mysql_prefix));
