This package provides Trello OAuth 1.0 support for the PHP League's OAuth 1.0 Client.

Installation

To install, use composer:

composer require league/oauth1-trello

Usage

Usage is the same as The League's OAuth client, using \League\OAuth1\Client\Server\Trello as the server.

Authenticating with OAuth 1.0

// Create a server instance.
$server = new \League\OAuth1\Client\Server\Trello([
    'identifier'              => 'your-identifier',
    'secret'                  => 'your-secret',
    'callbackUri'             => 'http://your-callback-uri/',
    // The following can be used to set defaults for the server
    'scope'                   => 'read',
    'expiration'              => '1day',
    'name'                    => 'Trello App'
]);

// Obtain Temporary Credentials and User Authorization
if (!isset($_GET['oauth_token'], $_GET['oauth_verifier'])) {

    // First part of OAuth 1.0 authentication is to
    // obtain Temporary Credentials.
    $temporaryCredentials = $server->getTemporaryCredentials();

    // Store credentials in the session, we'll need them later
    $_SESSION['temporary_credentials'] = serialize($temporaryCredentials);
    session_write_close();

    // Second part of OAuth 1.0 authentication is to obtain User Authorization
    // by redirecting the resource owner to the login screen on the server.
    // Create an authorization url.
    $authorizationUrl = $server->getAuthorizationUrl($temporaryCredentials);

    // Redirect the user to the authorization URL. The user will be redirected
    // to the familiar login screen on the server, where they will login to
    // their account and authorize your app to access their data.
    header('Location: ' . $authorizationUrl);
    exit;

// Obtain Token Credentials
} else {

    try {

        // Retrieve the temporary credentials we saved before.
        $temporaryCredentials = unserialize($_SESSION['temporary_credentials']);

        // We will now obtain Token Credentials from the server.
        $tokenCredentials = $server->getTokenCredentials(
            $temporaryCredentials,
            $_GET['oauth_token'],
            $_GET['oauth_verifier']
        );

        // We have token credentials, which we may use in authenticated
        // requests against the service provider's API.
        echo $tokenCredentials->getIdentifier() . "\n";
        echo $tokenCredentials->getSecret() . "\n";

        // Using the access token, we may look up details about the
        // resource owner.
        $resourceOwner = $server->getResourceOwner($tokenCredentials);

        var_export($resourceOwner->toArray());

        // The server provides a way to get an authenticated API request for
        // the service, using the access token; it returns an object conforming
        // to Psr\Http\Message\RequestInterface.
        $request = $server->getAuthenticatedRequest(
            'GET',
            'http://your.service/endpoint',
            $tokenCredentials
        );

    } catch (\League\OAuth1\Client\Exceptions\Exception $e) {

        // Failed to get the token credentials or user details.
        exit($e->getMessage());

    }

}

Configuring your server

In order to complete the authorization flow with your user, you will need to provide three additional pieces of information.

You may configure your server to include this information when creating the server.

// Create a server instance.
$server = new \League\OAuth1\Client\Server\Trello([
    'identifier'              => 'your-identifier',
    'secret'                  => 'your-secret',
    'callbackUri'             => 'http://your-callback-uri/',
    'scope'                   => 'read',
    'expiration'              => '1day',
    'name'                    => 'Trello App'
]);

You may also provide this information when creating your authorization url.

// Create a server instance.
$server = new \League\OAuth1\Client\Server\Trello([
    'identifier'              => 'your-identifier',
    'secret'                  => 'your-secret',
    'callbackUri'             => 'http://your-callback-uri/',
]);

$temporaryCredentials = $server->getTemporaryCredentials();

$options = [
    'scope'                   => 'read',
    'expiration'              => '1day',
    'name'                    => 'Trello App'
];

$authorizationUrl = $server->getAuthorizationUrl($temporaryCredentials, $options);

Configuration provided when creating your authorization url with take precedence over default configuration.

Sending one-off requests

You may use the server to create authenticated requests for one-off or trivial needs. If your needs are more robust, trello-php is recommended.

$server = new \League\OAuth1\Client\Server\Trello([
    'identifier'              => 'your-identifier',
    'secret'                  => 'your-secret',
    'callbackUri'             => 'http://your-callback-uri/',
]);

$token = 'your-resource-owner-token';
$secret = 'your-resource-owner-secret';

$tokenCredentials = new \League\OAuth1\Client\Credentials\TokenCredentials($token, $secret);

$request = $server->getAuthenticatedRequest(
    'get',
    'https://api.trello.com/1/members/me/boards',
    $tokenCredentials
);

$client = new \GuzzleHttp\Client();

$response = $client->send($request);

Running the included example

This project contains some example code within the example directory at the root of this project.

First, open the example/index.php file and update the server configuration with your Trello App Identifier and Secret.

Then run the code in your browser. Using the built-in server provided by PHP may be the fastest options. From the command line, and at the root of the project running the following command.

php -S localhost:9000 -t example

The built-in web server should begin running and when you browse to http://localhost:9000 in your favorite browser, you can begin testing your configuration.

Testing

$ ./vendor/bin/phpunit
$ ./vendor/bin/phpcs src --standard=psr2 -sp
