TwitterOAuth media/upload allways get Invalid or expired token

[official_gasm]

Using TwitterOAuth upload function with media/upload gives me always Invalid or expired token. That’s my code:
$connection = new TwitterOAuth($this->twitterParameters[‘consumer_key’],$this->twitterParameters[‘consumer_secret’]);
$connection->oauth(‘oauth/request_token’,array(‘oauth_callback’=>$this->twitterParameters[‘callback_url’]))
$oauth_token = $response[‘oauth_token’];
$oauth_token_secret = $response[‘oauth_token_secret’];
$connection = new TwitterOAuth(
$this->twitterParameters[‘consumer_key’],
$this->twitterParameters[‘consumer_secret’],
$oauth_token,
$oauth_token_secret
);
$connection->upload(‘media/upload’,[‘media’ => ‘/var/www/gasm.com/app/…/web/media/gasm/models/hopeeden/galleries/28052018085841/ce600c6c188e508259f8919c08c5f9b7.jpg’])

Do you know what I’m doing wrong?
Thanks in advance.

You can’t use a request token for authentication. They are not tied to a user. Once you get a request token you have to send a user to twitter.com for them to authorize and then when they return to your site you need to exchange the request token for an access token. That access token can be used to perform actions as a user.

You can see the full flow on https://twitteroauth.com/redirect.php
