twitter-rest

A simple Class to interface with Twitter API v1.1 using OAuth, and return tweets as JSON via a get method. Uses RestService and twitteroauth, _(*1)

Install

Requires https://github.com/marcj/php-rest-service, _(*2)

Install twitter-rest with Composer:, _(*3)

• https://packagist.org/packages/mutantlabs/twitter-rest
• More information available under https://packagist.org/.

Create a composer.json:, _(*4)

{
    "require": {
        "mutantlabs/twitter-rest": "dev-master"
    }
}

and run, _(*5)

$ wget http://getcomposer.org/composer.phar
$ php composer.phar install

Requirements

• PHP 5.3 and above.
• PHPUnit to execute the test suite.
• Setup PATH_INFO in mod_rewrite (.htaccess) or other webserver configuration

Example:, _(*6)

//apache .htaccess
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Config

create config.php as follows:, _(*7)

Set your config.php (uses twitteroauth from https://github.com/abraham/twitteroauth), _(*8)

define('CONSUMER_KEY', 'CONSUMER_KEY_HERE');
define('CONSUMER_SECRET', 'CONSUMER_SECRET_HERE');
define('OAUTH_TOKEN', 'OAUTH_TOKEN_HERE');
define('OAUTH_TOKEN_SECRET', 'OAUTH_TOKEN_SECRET_HERE');
define('OAUTH_CALLBACK', 'http://example.com/twitteroauth/callback.php');

Example use of TwitterRestAPI

include the vendor/autoload.php to make the class in your script available., _(*9)

include 'vendor/autoload.php';

Basic use:

Construct new TwitterRestAPI, _(*10)

use TwitterRest\TwitterRestAPI;
require_once('config.php');
$twitterRestApi = new TwitterRestAPI();

Get some tweets, _(*11)

$tweets = $twitterRestApi->getCachedUserStatus();
$arrTweets = array();
foreach($tweets as $key => $status) {
    $arrTweets[$key] = array(
        'created_at' => $status->created_at,
        'text' => $status->text
    );
}
echo json_encode($arrTweets);

Note - to use getCachedUserStatus() - you need to make your apache server the owner of twitter_result.data:, _(*12)

sudo chown -R www-data:www-data twitter_result.data

#Create a REST API Method using php-rest-service

use TwitterRest\TwitterRestAPI;
require_once('config.php');

TwitterRestAPI::create('/')
    ->addGetRoute('', function(){
        $twitterRestApi = new TwitterRestAPI();
        $tweets = $twitterRestApi->getCachedUserStatus();
        $arrTweets = array();
        foreach($tweets as $key => $status) {
            $arrTweets[$key] = array(
                'created_at' => $status->created_at,
                'text' => $status->text
            );
        }
        return $arrTweets;
    })
    ->run();

Extended Auth flow taken from https://github.com/abraham/twitteroauth, _(*13)

    ->addGetRoute('authenticate', function(){
            //When a user lands on /authenticate we build a new TwitterOAuth object using the client credentials.
            $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);

            //Using the built $connection object you will ask Twitter for temporary credentials. The oauth_callback value is required.
            $temporary_credentials = $connection->getRequestToken(OAUTH_CALLBACK);

            //Once we have temporary credentials the user has to go to Twitter and authorize the app to access and updates their data.
            $redirect_url = $connection->getAuthorizeURL($temporary_credentials, FALSE);

            return array($temporary_credentials,$redirect_url);
        })

The user is now on twitter.com and may have to login. Once authenticated with Twitter they will will either have to click on allow/deny, or will be automatically redirected back to the callback. in this case its example.domain.com/success, _(*14)

Once the user has returned to /success and allowed access we need to build a new TwitterOAuth object using the temporary credentials., _(*15)

        ->addGetRoute('success', function(){
            $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $_GET['oauth_token'],
                $_GET['oauth_verifier']);

            //Now we ask Twitter for long lasting token credentials. These are specific to the application and user and will act like password to make future requests.
            $token_credentials = $connection->getAccessToken($_REQUEST['oauth_verifier']);

            Here we can from our token credentials back to the application (i'd suggest a more secure method of sending these than encoded JSON. but here for example):
            return array($token_credentials);
        })

From here with the token credentials we build a new TwitterOAuth object., _(*16)

$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $token_credentials['oauth_token'],
$token_credentials['oauth_token_secret']);

And make requests authenticated as the user:, _(*17)

$status = $connection->post('statuses/update', array('status' => 'Text of status here', 'in_reply_to_status_id' => 123456));
