README

Install with composer... composer require CrixuAMG/passport-custom-request-grant

Versions

• Laravel 5.4 - Use version ^1.0
• Laravel 5.3 - Use version ^0.1

Setup

• Add CrixuAMG\Passport\CustomRequestGrantProvider to your list of providers after Laravel\Passport\PassportServiceProvider.
• Add byPassportCustomRequest($request) method to your User model (or whatever model you have configured to work with Passport).
  • The method should accept an Illuminate\Http\Request object.
  • You should authorize and retrieve user based on this request
  • If you find that the request met your requirement, return the User model.
  • If the request did not satisfy your requirement, return null

How to use

• Make a POST request to https://your-site.com/oauth/token, just like you would a Password or Refresh grant.
• The POST body should contain grant_type = custom_request.
• The request will get routed to your User::byPassportCustomRequest() function, where you will determine if access should be granted or not.
• An access_token and refresh_token will be returned if successful.

Example

Here is what a User::byPassportCustomRequest() method might look like...

/**
 * Verify and retrieve user by custom token request.
 *
 * @param \Illuminate\Http\Request $request
 *
 * @return \Illuminate\Database\Eloquent\Model|null
 * @throws \League\OAuth2\Server\Exception\OAuthServerException
 */
public function byPassportCustomRequest(Request $request)
{
    try {
        if ($request->get('sso_token')) {
            return $this->bySsoToken($request->get('sso_token'));
        }
    } catch (\Exception $e) {
        throw OAuthServerException::accessDenied($e->getMessage());
    }
    return null;
}

In this example, the app is able to authenticate a user based on an sso_token property from a submitted JSON payload. The bySsoToken is this app's way of doing that. It will return null or a user object. It also might throw exceptions explaining why the token is invalid. The byPassportCustomRequest catches any of those exceptions and converts them to appropriate OAuth exception type. If an ssoToken is not present on the request payload, then we return null which returns an invalid_credentials error response:

{
  "error": "invalid_credentials",
  "message": "The user credentials were incorrect."
}
