Linkedin: How to make api calls using access token? - zend-framework

Question

I am storing the linkedin access token in database. This is the token that is stored in my database:
oauth_token=xxxxxxxxxxxxxxxxxxx&oauth_token_secret=xxxxxxxxxxxxxxxxxxx&oauth_expires_in=5183998&oauth_authorization_expires_in=5183998
I want to retrieve the linkedin connections using this access token. I am trying to make a call like this:
$a = new Zend_Oauth_Token_Access();
$client = $a->getHttpClient( array(
'siteUrl' => LIN_SITE_URL,
'callbackUrl' => LIN_SITE_CALLBACK_URL,
'requestTokenUrl' => LIN_REQUEST_TOKEN_URL,
'userAuthorizationUrl' => LIN_USER_AUTHORIZATION_URL,
'accessTokenUrl' => LIN_ACCESS_TOKEN_URL,
'consumerKey' => LIN_CONSUMER_KEY,
'consumerSecret' => LIN_CONSUMER_SECRET
) );
$client->setUri('http://api.linkedin.com/v1/people/~/connections:(id,first-name,last-name,picture-url)');
$client->setParameterGet('token',$linToken);
$client->setMethod(Zend_Http_Client::GET);
$response = $client->request();
$content = $response->getBody();
$data = json_decode(Zend_Json::fromXml($content, false));
print_r($data); echo "<br/>";
The error i am getting here is:
stdClass Object ( [error] => stdClass Object ( [status] => 404 [timestamp] => 1349429996351 [request-id] => 8U8A1UNF1V [error-code] => 0 [message] => Could not find person based on: ~ ) )
Is this the correct way to make a call or am i doing something wrong here. I am using zend framework.
Thanks.

Answer 1

I was able to solve the problem by passing the outh_token and outh_token_secret as an array to the setParams() of Zend_Oauth_Token_Access as below:
$a = new Zend_Oauth_Token_Access;
$a->setParams(array(
'oauth_token' => 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
'oauth_token_secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx'
));

In your code example I don't see where you're setting the access token and secret. I just see that you're instantiating the $a variable:
$a = new Zend_Oauth_Token_Access();
Are you retrieving the access token and secret from you database then setting it to the $a variable? Something like this:
$a->setToken($row['token'])
->setTokenSecret($row['secret']);
By the way, this is a good reference for using Zend and LinkedIn: http://www.contentwithstyle.co.uk/content/linkedin-and-zendoauth/
