PHP Oauth Error Invalid Signature

Question

I am trying to start with OAuth 1.0 in PHP and I am having a strange problem. I created a pseudo-consumer that generates a signature in accordance with the specification and sends it using parameters through POST for the provider. Consumer use:

$oauth_consumer_key = '123';
$oauth_consumer_secret = '456';

$oauth_signature_method = 'HMAC-SHA1';
$oauth_timestamp = time();
$oauth_nonce = uniqid();
$oauth_version = '1.0';
$oauth_callback = 'http://localhost/oauth/callback';

$oauth = new OAuth($oauth_consumer_key, $oauth_consumer_secret);
$oauth->enableDebug();

$oauth_signature = $oauth->generateSignature('POST', $oauth_callback, array($oauth_consumer_key, $oauth_signature_method, $oauth_timestamp, $oauth_nonce, $oauth_version));

On the Providers side, everything works as intended. All values ​​obtained:

object(OAuthProvider)[1]
  public 'consumer_key' => string '123' (length=3)
  public 'consumer_secret' => string '456' (length=3)
  public 'nonce' => string '5390610001c90' (length=13)
  public 'token' => null
  public 'token_secret' => null
  public 'timestamp' => string '1401970944' (length=10)
  public 'version' => string '1.0' (length=3)
  public 'signature_method' => string 'HMAC-SHA1' (length=9)
  public 'callback' => string 'http://localhost/oauth/callback' (length=31)
  public 'request_token_endpoint' => boolean true
  public 'signature' => string '8lNbnGTOen4TEOHS9KcpgCiBl+M=' (length=28)

But this is the end of the honeymoon - an attempt to verify the signature causes an error: signature_invalid . This is what I used on the Providers side:

$provider = new OAuthProvider();
$provider->isRequestTokenEndpoint(true);
$provider->consumerHandler('lookupConsumer');
$provider->timestampNonceHandler('timestampNonceChecker');

try
{
    $request_verified = $provider->checkOAuthRequest();
}
catch(OAuthException $e)
{
    echo $provider->reportProblem($e);
}

and what I get as a problem report:

oauth_problem=signature_invalid&debug_sbs=POST&http%3A%2F%2Flocalhost%2Foauth%2Fcustom_auth%2Frequest_token.php&oauth_callback%3Dhttp%253A%252F%252Flocalhost%252Foauth%252Fcallback%26oauth_consumer_key%3D123%26oauth_nonce%3D5390610001c90%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1401970944%26oauth_version%3D1.0

$consumer_key      = 'key';
$consumer_secret   = 'secret';
$request_token_url = 'http://someurl.com/oauth/request-token';

$oauth = new OAuth($consumer_key, $consumer_secret);
$oauth->enableDebug(); //helpful debug

try {
    $oauth->getRequestToken($request_token_url);
} catch (OAuthException $e) {
    echo OAuthProvider::reportProblem($e); //easier to debug oauth exceptions
}

//this should hold the `request_token` and `request_token_secret` parameters for you to call getAccessToken
$response = json_decode($oauth->getLastResponse());

, http://someurl.com/oauth/request-token, :

$provider = new OAuthProvider();
$provider->consumerHandler(array($this,'consumerHandler'));
$provider->timestampNonceHandler(array($this,'timestampNonceHandler'));
$provider->tokenHandler(array($this,'tokenHandler'));
$provider->setRequestTokenPath('/oauth/request-token');

try {
    $request_verified = $provider->checkOAuthRequest();
} catch(OAuthException $e) {
    echo $provider->reportProblem($e);
}
//provider now holds all the required timestamp, nonce, and signature
