Hello,
I am trying to create an Add-on for XenForo and I am using Zend’s Client framework to make the calls instead of cURL.
When I try, I keep getting this error:
Could not authenticate with OAuth.
This is part of the code that deals with twitter:
class xenCODE_Socialize_Helper_Twitter
{
private static $url = ‘https://api.twitter.com/1/statuses/update.json’;
public static function tweet($message)
{
$options = XenForo_Application::get(‘options’);
try
{
$client = XenForo_Helper_Http::getClient(self::$url);
foreach(self::getParams($message) as $key => $value)
{
$client->setParameterPost($key, $value);
}
$client->setParameterPost(‘oauth_signature’, self::getSig($message));
$response = $client->request('POST');
return $response->getBody().self::getSig($message);
}
catch (Zend_Http_Client_Exception $e)
{
return false;
}
}
private static function getSig($message)
{
$options = XenForo_Application::get('options');
$keyParts = array(
$options->xenCODE_XS_TCS,
$options->xenCODE_XS_TAS
);
$keyParts = self::urlencode_rfc3986($keyParts);
$key = implode('&', $keyParts);
return self::urlencode_rfc3986(base64_encode(hash_hmac('sha1', self::getBaseString($message), $key, true)));
}
private static function getParams($message)
{
$options = XenForo_Application::get('options');
return array(
'oauth_consumer_key' => $options->xenCODE_XS_TCK,
'oauth_nonce' => md5(time().mt_rand()),
'oauth_timestamp' => time(),
'oauth_token' => $options->xenCODE_XS_TAT,
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_version' => '1.0',
'status' => $message
);
}
public static function urlencode_rfc3986($input)
{
if(is_array($input))
{
return array_map(array('xenCODE_Socialize_Helper_Twitter', 'urlencode_rfc3986'), $input);
}elseif(is_scalar($input))
{
return str_replace(
'+',
' ',
str_replace('%7E', '~', rawurlencode($input))
);
}else{
return '';
}
}
private static function getBaseString($message)
{
$parts = array(
'POST',
self::$url,
self::buildQuery(self::getParams($message))
);
return self::urlencode_rfc3986(implode('&', $parts));
}
private static function buildQuery(array $input)
{
$parts = array();
foreach($input as $key => $value)
{
$parts[] = $key.'='.$value;
}
return implode('&', $parts);
}
}
