Zend Framework: Zend_Oauth and Zend_Service_Twitter

Question

First of all, I am able to successfully authenticate using Oauth. I am using Padraic\'s tutorial found here: http://blog.astrumfutura.com/archives/411-Writing-A-Simple-Twitter-C

Answer 1

We've done almost exactly this for Twitgoo.com (runnining full zend framework and twitter oauth login integration).

To generalize, we created two Zend_Auth_Identity models - one for password login one for oauth login. (actually 3 where 1 is 'anon' and fails all Zend_Auth). The identity holds the username and our local userid at minimum - for oauth it holds the Zend_Oauth_Token, for password it holds the password (we never store it). These identity models are what the Zend_Auth_Adapter for twitter returns, and what we pass to our Zend_Service_Twitter extension.

our twitter then takes in a Identity model, and handles setting up twitter for it.

class Tg_Service_Twitter extends Zend_Service_Twitter {

    public function __construct(Tg_Auth_Identity $login) {
        if ($login instanceof Tg_Auth_Identity_Password) {
            $password = $login->getPassword();
        } else if ($login instanceof Tg_Auth_Identity_Oauth) {
            $password = null;
            $httpClient = $login->getOauthToken()
                ->getHttpClient(Tg_Service_Twitter_Helper::getOauthOptions());
            self::setHttpClient($httpClient);
        } else {
            throw new Exception('not done yet');
        }

        $username = $login->getUsername();

        self::setupHttpClient();
        parent::__construct($username, $password);

        if ($login instanceof Tg_Auth_Identity_Oauth) {
            //makes it skip basic auth
            $this->_authInitialized = true;
        }
    }

The $username is required to be set from the login (which twitter gives back to you during getting access token) by some of the Service_Twitter functions.

I can add more specifics if needed.

Okay, I placed a bounty on this question and I do not know how to remove it. I am going to answer it myself. For others to know if they are encountering the same problem.

First, in my application.ini I have something like this:

oauth.version           = "1.0"
oauth.signatureMethod   = "HMAC-SHA1"
oauth.requestScheme     = "header"
oauth.siteUrl           = "http://mysite.com/twitter/public"
oauth.callbackUrl       = "http://mysite.com/twitter/public/login/callback"
oauth.requestTokenUrl   = "http://twitter.com/oauth/request_token"
oauth.authorizeUrl      = "http://twitter.com/oauth/authorize"
oauth.accessTokenUrl    = "http://twitter.com/oauth/access_token"
oauth.consumerKey       = "xxxxxx"
oauth.consumerSecret    = "xxxxxxxxxx"

Then, my new model is this:

<?php

/**
 * I'm trying to extend Zend_Service_Twitter to use Oauth instead
 */

require_once 'Zend/Service/Twitter.php';

class Mytwitterapp_Twitteroauth extends Zend_Service_Twitter
{
    /**
     * Oauth
     * @var Zend_Oauth_Token_Access
     */
    protected $_token;

    /**
     * Array for Zend_Oauth_Consumer (i think)
     * @var Zend_Config_Ini
     */
    protected $_config;

    /**
     * @param object $token
     * @return void
     */
    public function __construct(Zend_Oauth_Token_Access $token)
    {
        $this->_config = new Zend_Config_Ini(APPLICATION_INI, APPLICATION_ENV);
        $this->_token = $token;
        $this->setUri('http://twitter.com');
        //$this->_authInitialized = true;

        self::setHttpClient($token->getHttpClient($this->_config->oauth->toArray()));
    }
}

Using it would look something like this:

$oauth = new Zend_Session_Namespace('Twitter_Oauth');
$token = unserialize($oauth->twitter_access_token);
$this->_twitter = new Mytwitterapp_Twitteroauth($token);

Answer 3

Man, thanks for this. Was just about losing my mind on a new project that already had a bunch of Zend_Service_Twitter calls in it.
