Getting error while calling magento 1.9.2 rest api

Question

I am using Magento 1.9.2 vesrion for. Using below code for calling rest api.

public function indexAction() {

    //Basic parameters that need to be provided for oAuth authentication
    //on Magento
    $params = array(
        'siteUrl' => 'http://127.0.0.1:8080/magentodemo/',
        'requestTokenUrl' => 'http://127.0.0.1:8080/magentodemo/oauth/initiate',
        'accessTokenUrl' => 'http://127.0.0.1:8080/magentodemo/oauth/token',
        'authorizeUrl' => 'http://127.0.0.1:8080/magentodemo/admin/oauth_authorize',//This URL is used only if we authenticate as Admin user type
        'consumerKey' => 'c359b57d0d069a336db94fa4aabd61ce',//Consumer key registered in server administration
        'consumerSecret' => '2ef029c871b7c013619cc15445a83c25',//Consumer secret registered in server administration
        'callbackUrl' => 'http://127.0.0.1:8080/magentodemo/restconnect/index/callback',//Url of callback action below
    );

    // Initiate oAuth consumer with above parameters
    $consumer = new Zend_Oauth_Consumer($params);
    // Get request token
    $requestToken = $consumer->getRequestToken();
    // Get session
    $session = Mage::getSingleton('core/session');
    // Save serialized request token object in session for later use
    $session->setRequestToken(serialize($requestToken));
    // Redirect to authorize URL
    $consumer->redirect();

    return;
}

public function callbackAction() {

    //oAuth parameters
    $params = array(
        'siteUrl' => 'http://127.0.0.1:8080/magentodemo/',
        'requestTokenUrl' => 'http://127.0.0.1:8080/magentodemo/oauth/initiate',
        'accessTokenUrl' => 'http://127.0.0.1:8080/magentodemo/oauth/token',
        'consumerKey' => 'c359b57d0d069a336db94fa4aabd61ce',
        'consumerSecret' => '2ef029c871b7c013619cc15445a83c25'
    );

    // Get session
    $session = Mage::getSingleton('core/session');
    // Read and unserialize request token from session
    $requestToken = unserialize($session->getRequestToken());
    // Initiate oAuth consumer
    $consumer = new Zend_Oauth_Consumer($params);
    // Using oAuth parameters and request Token we got, get access token
    $acessToken = $consumer->getAccessToken($_GET, $requestToken);
    // Get HTTP client from access token object
    $restClient = $acessToken->getHttpClient($params);
    // Set REST resource URL
    $restClient->setUri('http://127.0.0.1:8080/magentodemo/api/rest/products');
    // In Magento it is neccesary to set json or xml headers in order to work
    $restClient->setHeaders('Accept', 'application/json');
    // Get method
    $restClient->setMethod(Zend_Http_Client::GET);
    //Make REST request
    $response = $restClient->request();
    // Here we can see that response body contains json list of products
    Zend_Debug::dump($response);

    return;
}

Getting below error every time

Answer 1

There was a small fix for above issue. But it takes my 1 day to fix it. In my system apache was running on 8080 port. There is issue in magento oauth to read port while URI validation.

I have stopped other service (IIS or Skype), in my case it was IIS. and port apache on 80. This is the default port.

Hope this will help to someone!!!
