@Kakakatt: Sure, here it is. The consumer class:


// app/controllers/components/oauth_consumers/google_consumer.php
class GoogleConsumer extends AbstractConsumer {
    public function __construct() {
        parent::__construct('anonymous', 'anonymous');
    }
}

And the controller:


// app/controllers/google_example_controller.php
class GoogleExampleController extends AppController {
    public $uses = array();
    public $components = array('OauthConsumer');
	
    public function index() {
        $requestToken = $this->OauthConsumer->getRequestToken('Google', 'https://www.google.com/accounts/OAuthGetRequestToken', 'http://test.localhost/google_example/callback', 'POST', array('scope' => 'http://picasaweb.google.com/data'));
        $this->Session->write('request_token', $requestToken);
	
        $this->redirect('https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token=' . $requestToken->key);
    }
	
    public function callback() {
        $requestToken = $this->Session->read('request_token');
        $accessToken = $this->OauthConsumer->getAccessToken('Google', 'https://www.google.com/accounts/OAuthGetAccessToken', $requestToken);
        
        debug($accessToken);
        exit;
    }
}

I hope this helps. And regarding OAuth and Picasa: at least according to Google's OAuth announcement Picasa should also be supported.

May I read your code ? I have used Oauth component 2009-09-05 version.
The link you provided do not deal with the problem, it was just warning of mistake. I have read sources from Google API that: Picasa is just compatible with Auth http://code.google.com/apis/picasaweb/docs/1.0/developers_guide_php.html

@Kakakatt: Hm, I just tried it myself and it worked fine without removing the param. Do you use the latest version of the oauth component? What is the problem with picasa? At least from this ticket http://code.google.com/p/gdata-issues/issues/detail?id=701 it seems like OAuth is supported by picasa.

I found the error.It occurs when I tried to receive the request token, There was a oauth_callback_confirmed string flowing. It looks like this:

object(OAuthToken)#30 (2) { ["key"]=> string(30) "4/kJgZjbdAcEujx8acnVOyaPYJZKRa" ["secret"]=> string(54) "N4lAsT6qQnZahUTbRF1Cm66/&oauth_callback_confirmed=true" }

Yep, you need to remove the call back string and then the problem will be solved

object(OAuthToken)#30 (2) { ["key"]=> string(30) "4/kJgZjbdAcEujx8acnVOyaPYJZKRa" ["secret"]=> string(54) "N4lAsT6qQnZahUTbRF1Cm66/" }

But I have a other problem that OAuth can’t be used with picasa. Are there anyone want to help me ? Thanks

@Kakakatt: Your code looks correct. Did you check with a tool like Wireshark whether a request was performed? And is the OpenSSL extension activated in your php.ini?

Hope this helps!

oops, what 's wrong with my code :| ?

 public function index() {
		
        $requestToken = $this->OauthConsumer->getRequestToken('Google','https://www.google.com/accounts/OAuthGetRequestToken');
		//var_dump($requestToken); exit();
        $this->Session->write('requestToken', $requestToken);
        $this->redirect('https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token='.$requestToken->key);
    }

	 public function callback() {
        $requestToken = $this->Session->read('requestToken');
        $accessToken = $this->OauthConsumer->getAccessToken('Google', 'https://www.google.com/accounts/OAuthGetAccessToken', $requestToken);
    }

In google_consumer.php

class GoogleConsumer extends AbstractConsumer {
    public function __construct() {
        parent::__construct('my key', 'my secret');
    }
}

In http_socket.php the code

$response = null;
		
		while ($data = $this->read()) {
			
			$response .= $data;				
		}

It doesn't work, $response is always NULL !!!

Please help me! I use your OAuth component with google service but i have a problem. I don’t know why $requestToken is NULL !!! My code is:

@HHuan: Hm, I am not sure I understand your question. What do you try to accomplish? In the code I noticed two things: in the google() method you have to redirect to an “authorize” page at the end of the method. And the code below “below i dont know how to handle it” you have to use a Google url, you can’t post to twitter with an access token from Google.

Hope that helps a bit!
