README

This package provides Yammer OAuth 2.0 support for the PHP League's OAuth 2.0 Client.

Installation

Requirements

• PHP version 5.5 or higher.

Installing via Composer

The preferred method of installing this library is through the Composer dependency management tool.

Add the following dependency to your composer.json:

{
  "require": {
    "upro/oauth2-yammer": "~0.1"
  }
}

Or simply run the following command line to install the latest stable version:

$ composer require upro/oauth2-yammer

Then, require the vendor/autoload.php file to enable the autoloading mechanism provided by Composer. Otherwise, your application won't be able to find the classes of this library.

Usage

Usage is the same as The League's OAuth client, using \UPro\OAuth2\Client\Provider\Yammer as the provider.

Authorization Code Flow

require __DIR__.'/vendor/autoload.php';

$provider = new UPro\OAuth2\Client\Provider\Yammer([
    'clientId'          => '{yammer-client-id}',
    'clientSecret'      => '{yammer-client-secret}',
    'redirectUri'       => 'https://example.com/callback-url',
]);

// If we don't have an authorization code then get one
if (!isset($_GET['code'])) {
    $authorizationUrl = $provider->getAuthorizationUrl();
    $_SESSION['oauth2state'] = $provider->getState();
    header('Location: '.$authorizationUrl);
    exit;

// Check given state against previously stored one to mitigate CSRF attack
} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {
    unset($_SESSION['oauth2state']);
    exit('Invalid state');

} else {

    // Try to get an access token (using the authorization code grant)
    $token = $provider->getAccessToken('authorization_code', [
        'code' => $_GET['code']
    ]);

    // Optional: Now you have a token you can look up a users profile data
    try {

        // We got an access token, let's now get the user's details
        $user = $provider->getResourceOwner($token);

        // Use these details to create a new profile
        printf('Hello %s!', $user->getName());

    } catch (Exception $e) {

        // Failed to get user details
        exit('Oh dear...');
    }

    // Use this to interact with an API on the users behalf
    echo $token->getToken();
}
