Protected Properties

Property Type Description
$conf Array of persistent variables stored.
$oldRefreshToken string Keep track of the old refresh token. So we can unset the old refresh tokens when a new one is issued.
$storage oauth2\IOAuth2Storage Storage engine for authentication server
$usedAuthCode OAuth2\Model\IOAuth2AuthCode Keep track of the used auth code. So we can mark it as used after successful authorization

Public Methods

Method Description
__construct ( oauth2\IOAuth2Storage $storage, array $config = [] ) Creates an OAuth2.0 server-side instance.
createAccessToken ( OAuth2\Model\IOAuth2Client $client, mixed $data, string | null $scope = null, integer | null $access_token_lifetime = null, boolean $issue_refresh_token = true, integer | null $refresh_token_lifetime = null ) : array Handle the creation of access token, also issue refresh token if support.

finishClientAuthorization() public method

After the user has approved or denied the access request the authorization server should call this function to redirect the user appropriately.
See also: http://tools.ietf.org/html/draft-ietf-oauth-v2-20#section-4
public finishClientAuthorization ( boolean $isAuthorized, mixed $data = null, Request $request = null, string | null $scope = null ) : Response
$isAuthorized boolean true or false depending on whether the user authorized the access.

genAccessToken() protected method

Implementing classes may want to override this function to implement other access token generation schemes.
See also: OAuth2::genAuthCode()
protected genAccessToken ( ) : string
return string An unique access token.

genAuthCode() protected method

Implementing classes may want to override this function to implement other auth code generation schemes.
See also: OAuth2::genAccessToken()
protected genAuthCode ( ) : string
return string An unique auth code.

getAuthorizationHeader() protected method

According to draft 20, standard basic authorization is the only header variable required (this does not apply to extended grant types). Implementing classes may need to override this function if need be.

getAuthorizeParams() protected method

- The redirect_uri is OPTIONAL as per draft 20. But your implementation can enforce it by setting CONFIG_ENFORCE_INPUT_REDIRECT to true. - The state is OPTIONAL but recommended to enforce CSRF. Draft 21 states, however, that CSRF protection is MANDATORY. You can enforce this by setting the CONFIG_ENFORCE_STATE to true.

verifyAccessToken() public method

The token is returned (as an associative array) if valid. The scope parameter defines any required scope that the token must have. If a scope param is provided and the token does not have the required scope, we bounce the request. Some implementations may choose to return a subset of the protected resource (i.e. "public" data) if the user has not provided an access token or if the access token is invalid or expired. The IETF spec says that we should send a 401 Unauthorized header and bail immediately so that's what the defaults are set to. You can catch the exception thrown and behave differently if you like (log errors, allow public access for missing tokens, etc)
See also: http://tools.ietf.org/html/draft-ietf-oauth-v2-20#section-7
public verifyAccessToken ( string $tokenParam, string $scope = null ) : OAuth2\Model\IOAuth2AccessToken
$tokenParam string
$scope string A space-separated string of required scope(s), if you want to check for scope.
return OAuth2\Model\IOAuth2AccessToken Token
