OAuth 2 Token Encoder
The OAuth 2 spec specifies token responses should be JSON. However XML users will be XML users so there's a draft spec extension which defines how OAuth responses should look in XML and Form Encoded formats:
https://tools.ietf.org/html/draft-richer-oauth-xml-01
{ "access_token":"2YotnFZFEjr1zCsicMWpAA", "token_type":"example", "expires_in":3600 }
<oauth> <access_token>2YotnFZFEjr1zCsicMWpAA</access_token> <token_type>example</token_type> <expires_in>3600</expires_in> </oauth>
access_token=2YotnFZFEjr1zCsicMWpAA&token_type=example&expires_in=3600
Installation
composer require radweb\oauth-token-encoding
Usage
There's a basic Radweb\OAuthTokenEncoding\OAuthTokenEncoder
class which when given an Accept
header and an array representing an OAuth token, will respond with the correct Content-Type
header and the correctly encoded OAuth token.
There's also adaptors for common libraries which will respond with a correct Response object:
OAuthTokenIlluminateAdaptor
for LaravelOAuthTokenSymfonyAdaptor
for SymfonyOAuthTokenPsrAdaptor
for any PSR-7 compatible libraries (although uses theZend\Diactoros
package as the implementation for the PSR-7 response)
Finally, if you're using the League\OAuth2\Server
package, there's a compatible LeagueOAuthExceptionFormatter
class for formatting exceptions from that library. If you're using it with Laravel, there's also LaravelOAuthExceptionHandlingMiddleware
for doing that automatically.
Basic Usage
// grab the "Accept" header from your request and pass it in $accept = 'application/xml'; // create an access token $oauthToken = [ "access_token" => "2YotnFZFEjr1zCsicMWpAA", "token_type" => "example", "expires_in" => 3600, "refresh_token" => "tGzv3JOkF0XG5Qx2TlKWIA", "example_parameter" => "example_value", ]; $encoder = new OAuthTokenEncoder; list($contentType, $body) = $encoder->encode($accept, $oauthToken); // return a response using the given body & content type
With League's OAuth 2 Server
The format returned by League\OAuth2\Server\AuthorizationServer
's issueAccessToken
method can be passed through to the encoder.
list($contentType, $body) = $encoder->encode($authorizationServer->issueAccessToken());
With Laravel / Lumen
Given an Illuminate\Http\Request
object, the adaptor will check the Accept
header of the request for application/json
, application/xml
or application/x-www-form-urlencoded
. If none are found, it assumes JSON.
$oauthToken = [ "access_token" => "2YotnFZFEjr1zCsicMWpAA", "token_type" => "example", "expires_in" => 3600, "refresh_token" => "tGzv3JOkF0XG5Qx2TlKWIA", "example_parameter" => "example_value", ]; // $request should be a Illuminate\Http\Request $adaptor = new OAuthTokenIlluminateAdaptor(new OAuthTokenEncoder, $request); // or.. $adaptor = OAuthTokenIlluminateAdaptor::make($request); $response = $adaptor->adapt($oauthToken); // $response is now an Illuminate\Http\Response
The response will contain the correctly encoded body, the correct Content-Type
header and the Cache-Control: no-store
header.
With Laravel OAuth 2 Server
use \LucaDegasperi\OAuth2Server\Authorizer; use \Radweb\OAuthTokenEncoding\ResponseAdaptors\OAuthTokenIlluminateAdaptor; Route::post('oauth/token', function(Authorizer $authorizer, OAuthTokenIlluminateAdaptor $adaptor) { return $adaptor->adapt($authorizer->issueAccessToken()); });
The format returned by League\OAuth2\Server\AuthorizationServer
's issueAccessToken
method can be passed through to the encoder.
With PSR-7
To construct a response, the
zendframework/zend-diactoros
package is required.
Given a PSR-7 request, the adaptor will check the Accept
header of the request for application/json
, application/xml
or application/x-www-form-urlencoded
. If none are found, it assumes JSON.
$oauthToken = [ "access_token" => "2YotnFZFEjr1zCsicMWpAA", "token_type" => "example", "expires_in" => 3600, "refresh_token" => "tGzv3JOkF0XG5Qx2TlKWIA", "example_parameter" => "example_value", ]; // $request should be a PSR-7 compliant Request object $adaptor = new OAuthTokenPsrAdaptor(new OAuthTokenEncoder, $request); // or.. $adaptor = OAuthTokenPsrAdaptor::make($request); $response = $adaptor->adapt($oauthToken); // $response is now a PSR-7 compliant Response object
The response will contain the correctly encoded body, the correct Content-Type
header and the Cache-Control: no-store
header.
Errors
If you're using Laravel OAuth 2 Server you can use the LaravelOAuthExceptionHandlingMiddleware
instead of the one provided in that package.
{ "error": "invalid_client", "error_description": "Client authentication failed." }
<oauth> <error>invalid_client</error> <error_description>Client authentication failed.</error_description> </oauth>
error=invalid_client&error_description=Client+authentication+failed.
