LinkedIn using Zend OAuth

Jeroen — Sun, 21 Mar 2010 16:29:41 +0000

Recently I needed to connect to LinkedIn and update the status of a user and also post a network update. I achieved the first using the superb article on the site of Formatix. But the latter was not that easy. The LinkedIn API documentation was not that clear on the ‘post network update’ subject, so I had to search another solution. I extended the class of Formatix with a updateNetwork method, and fixed some bugs I found with the use of the Zend Framework version 1.10. Long story short, the best thing to do is head over to his site for a good explanation about how the process works, and then just grab my update here if you need to do network updates too.

I might update it a bit more later on to have it wrap even better.

The bug I fixed is really small, there was a problem with the spelling of one parameter.. Here it is:

$this->options = array(
 'version' => '1.0',
 'localUrl' => $params['localUrl'],
 'callbackUrl' => $params['callbackUrl'],
 'requestTokenUrl' => 'https://api.linkedin.com/uas/oauth/requestToken',
 'userAuthorizationUrl' => 'https://api.linkedin.com/uas/oauth/authorize', // changed s to z
 'accessTokenUrl' => 'https://api.linkedin.com/uas/oauth/accessToken',
 'consumerKey' => $params['consumerKey'],
 'consumerSecret' => $params['consumerSecret']
 );

Here is the method I added to the class:

/*
 * @abstract: Performs a network update
 */
 public function updateNetwork($username, $message)
 {
 $this->client->setUri('https://api.linkedin.com/v1/people/~/person-activities');
 $this->client->setMethod(Zend_Http_Client::POST);
 $xml = $this->createXmlNetworkUpdate($username, $message);
 $this->client->setRawData($xml,'text/xml');
 $this->client->setHeaders('Content-Type', 'text/xml');
 $t = $this->client->request();
 }

 /*
 * @abstract: Creates THE XML string containing the Network update
 */
 private function createXmlNetworkUpdate($username, $message)
 {
 $xml = '';
 $xml .= 'linkedin-html';
 $xml .= '';
 $xml .= $username . ' says: ';
 $xml .= $message;
 $xml .= '';
 $xml .= '';

 return $xml;
 }

Not really much to it! Updates might come later, for now I hope this will do.

As a final wrap up, here is the full text class (note: this is a combination of my (small) update and all of the other beautiful work done by Formatix!):

options = array(
			'version' => '1.0',
			'localUrl' => $params['localUrl'],
			'callbackUrl' => $params['callbackUrl'],
			'requestTokenUrl' => 'https://api.linkedin.com/uas/oauth/requestToken',
			'userAuthorizationUrl' => 'https://api.linkedin.com/uas/oauth/authorize', // TODO (did) changed s to z
			'accessTokenUrl' => 'https://api.linkedin.com/uas/oauth/accessToken',
			'consumerKey' => $params['consumerKey'],
			'consumerSecret' => $params['consumerSecret']
		);

		// Instanciate Zend_Oauth_Consumer Class
		$this->consumer = new Zend_Oauth_Consumer( $this->options );

	}

	public function connect()
	{
		// Start Session to be able to store Request Token and Access Token
		session_start ();

		if ( !isset ( $_SESSION ['ACCESS_TOKEN'] )) {
		// We do not have any Access token Yet
		if (! empty ( $_GET )) {
		// But We have some parameters passed throw the URL

		// Get the LinkedIn Access Token
		$this->token = $this->consumer->getAccessToken ( $_GET, unserialize ( $_SESSION ['REQUEST_TOKEN'] ) );

		// Store the LinkedIn Access Token
		$_SESSION ['ACCESS_TOKEN'] = serialize ( $this->token );
		} else {
		// We have Nothing

		// Start Requesting a LinkedIn Request Token
		$this->token = $this->consumer->getRequestToken ();

		// Store the LinkedIn Request Token
		$_SESSION ['REQUEST_TOKEN'] = serialize ( $this->token );

		// Redirect the Web User to LinkedIn Authentication Page
		$this->consumer->redirect ();
		}
		} else {
		// We've already Got a LinkedIn Access Token

		// Restore The LinkedIn Access Token
		$this->token = unserialize ( $_SESSION ['ACCESS_TOKEN'] );

		}

		// Use HTTP Client with built-in OAuth request handling
		$this->client = $this->token->getHttpClient($this->options);

Blurry lights wallpapers

My last visit to the Fuse Club was a good one, great atmosphere. And while being there I took some shots, and some of them might be good wallpaper material. Grab the files at the Flickr set, enjoy!

Mobile version

Jeroen — Sun, 27 Dec 2009 22:17:07 +0000

I just installed a mobile plugin for wordpress so my site is accessible for mobile users too. Still have to work on the ‘work’ section.

Badge icons if you want

Jeroen — Sun, 13 Dec 2009 11:44:52 +0000

For someone I had to create a couple of badge/award like icons, to use on an award page. Since in the I used freeware icons as well from time to time, I thought it would be good to make them available. You can grab some png files right from my Flickr set, or just get the Photoshop file to get creative. In the file all items are smart objects, so you can easily scale and update the vector badges. I moved everything to Photoshop to add some outer glow (which in Illustrator is not that good, according to my humble self).

Enjoy and please let me know what you think!

Flickr Pro has come

Jeroen — Fri, 13 Nov 2009 10:29:46 +0000

Finally I made the move to Flickr pro. Just the feeling and thought knowing all my pictures are up there in the safe cloud, is a good feeling. Besides Flickr Pro I can advise dropbox to anyone too, you get 2 GB for free and it’s just a dead easy way to keep your documents backed up and synched between different machines, safely online.

More posts are for later, I’m looking to get more work online (I’m serious this time ).

Tiny Tumblers won!

Jeroen — Sun, 07 Jun 2009 16:06:21 +0000

Ok it’s been a while since my last post (actually it has been way too long), but I come with good news. Tiny Tumblers, a game I made along with 5 other persons at school, got a Multi Mania award. Multi Mania is a two day conference about multimedia and it ends with an awardshow with showcases of all the students. We got the price for our game in the according category.

Color Converter Widget

Jeroen — Tue, 03 Feb 2009 15:17:33 +0000

Color Converter enables easy conversion between color formats, and also gives some default output to be used in programming languages.

You can download it right here.

Note: this is my first (and maybe last) widget. I found a bunch of these widgets already out there, but none of them offered the rgb float format (rgb values between 0 and 1), and I needed that.

New stuff online soon

As the exams roll along, some new stuff will be up soon. Stay tuned.

Fireflies tutorial

Jeroen — Mon, 15 Dec 2008 07:37:34 +0000

After I put the fireflies wallpapers online, my friend proposed me to make a tutorial, since that could be usefull. I’ll work on it and put it online asap, maybe tonight.

Fireflies on your desktop

Jeroen — Mon, 15 Dec 2008 07:31:13 +0000

Don’t ask me why I called it fireflies but anyway, I was bored and made a desktop wallpaper, and generous as I am, wanted to share it. If anyone likes one of these, just download them. You can get all three in this zip package as well. It might be a bit bright, but I’m not going to make it again. Peace.
