Consuming Magento REST service using Zend_OAuth_Consumer

[agroverd]

I have a question for you. I test the code below with get request and function very well, but I need do a post request for create a product. I put the follow code but I receive an error message.

GET request

public function indexAction() {
	
			//Basic parameters that need to be provided for oAuth authentication
			//on Magento
			$params = array(
					'siteUrl' => 'http://localhost/magento/oauth',
					'requestTokenUrl' => 'http://localhost/magento/oauth/initiate',
					'accessTokenUrl' => 'http://localhost/magento/oauth/token',
					'authorizeUrl' => 'http://localhost/magento/admin/oAuth_authorize',//This URL is used only if we authenticate as Admin user type
					'consumerKey' => 'value',//Consumer key registered in server administration
					'consumerSecret' => 'value',//Consumer secret registered in server administration
					'callbackUrl' => Mage::getModel('adminhtml/url')->getUrl('*/sales_order_callapi/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://localhost/magento/oauth',
					'requestTokenUrl' => 'http://localhost/magento/oauth/initiate',
					'accessTokenUrl' => 'http://localhost/magento/oauth/token',
					'consumerKey' => 'value',
					'consumerSecret' => 'value'
			);
	
			// 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://localhost/magento/api/rest/products');
			// In Magento it is neccesary to set json or xml headers in order to work
			
			$restClient->setHeaders('Content-type', 'application/json');
			// Get method
			$restClient->setMethod(Zend_Http_Client::POST);
			
			
			$restClient->setParameterGet(array(
					'type_id'           => 'simple',
					'attribute_set_id'  => 4,
					'sku'               => 'SKUTEST2' . uniqid(),
					'weight'            => 1,
					'status'            => 1,
					'visibility'        => 4,
					'name'              => 'Simple Product',
					'description'       => 'Simple Description',
					'short_description' => 'Simple Short Description',
					'price'             => 69.95,
					'tax_class_id'      => 0,
			));  
			
			
			//Make REST request
			$response = $restClient->request();
			// Here we can see that response body contains json list of products
			Zend_Debug::dump($response);
	
			return;
		}

POST request

			$restClient->setHeaders('Content-type', 'application/json');
                        $restClient->setMethod(Zend_Http_Client::POST);
                        $restClient->setParameterPost(array(
					'type_id'           => 'simple',
					'attribute_set_id'  => 4,
					'sku'               => 'SKUTEST' . uniqid(),
					'weight'            => 1,
					'status'            => 1,
					'visibility'        => 4,
					'name'              => 'Simple Product',
					'description'       => 'Simple Description',
					'short_description' => 'Simple Short Description',
					'price'             => 69.95,
					'tax_class_id'      => 0,
                        $response = $restClient->request();

The error code is:

object(Zend_Http_Response)[330]
  protected 'version' => string '1.1' (length=3)
  protected 'code' => int 500
  protected 'message' => string 'Internal Server Error' (length=21)
  protected 'headers' => 
    array (size=7)
      'Date' => string 'Thu, 26 Oct 2017 08:50:00 GMT' (length=29)

      'Content-type' => string 'text/html; charset=UTF-8' (length=24)
  protected 'body' => string 'Service temporary unavailable' (length=29)

I config my admin user of magento who is conected with their code with All resources role and all acl attribute rules.

Thank you for your support

@agroverd

The below error comes up in Magento when the file maintenance.flag exist in your Magento root directory. 

protected 'body' => string 'Service temporary unavailable' (length=29)

So if you see this file then remove it. After this you shouldn't be seen this error again.

Thank you for your response Ravindra,

I don't have this file in my magento. This file is used for put magento in maintenance mode so I do not think the problem is due to that at all

Hi @agroverd

Check this out, problem seems similar to yours.

https://magento.stackexchange.com/questions/166895/how-to-add-product-using-rest-api

Beside this, make your that all required fields like 

content

etc are defined as object, not array while posting product data to Magento. Let me know the result.

Hi Ravindra,

I see the post that you comment me but the solution that the post say not is valid for me.

I want add the products use the zend oauth method and not the way the publication indicates that it is OAuth.

I have tried to add products into magento using SOAP and REST OAuth and the 2 ways function very well. But now I want use the zend OAuth method.

Best regards
