Dropbox Provider for the OAuth 2.0 Client

Dropbox Provider for OAuth 2.0 Client

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

Installation

To install, use composer:

composer require stevenmaguire/oauth2-dropbox

Note: Due API deprecation, we dropped support to Dropbox API v1. If you need use v1, please use ^2.0.0 version constraint:

composer require "stevenmaguire/oauth2-dropbox:^2.0.0"

Usage

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

Authorization Code Flow

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

if (!isset($_GET['code'])) {

    // If we don't have an authorization code then get one
    $authUrl = $provider->getAuthorizationUrl();
    $_SESSION['oauth2state'] = $provider->getState();
    header('Location: '.$authUrl);
    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->getId());

    } 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();
}

Refreshing a Token

Dropbox's OAuth implementation does not use refresh tokens. Access tokens are valid until a user revokes access manually, or until an app deauthorizes itself.

Testing

$ ./vendor/bin/phpunit
