getAuthorizationCode

Fetch authorization code data (probably the most common grant type).

public getAuthorizationCode(mixed $code): \OAuth2\Storage\An

Retrieve the stored data for the given authorization code.

Required for OAuth2::GRANT_TYPE_AUTH_CODE.

Parameters:

Parameter	Type	Description
`$code`	mixed	Authorization code to be check with.

Return Value:

associative array as below, and NULL if the code is invalid

setAuthorizationCode

Take the provided authorization code values and store them somewhere.

public setAuthorizationCode(mixed $code, mixed $client_id, mixed $user_id, mixed $redirect_uri, mixed $expires, mixed $scope = null, mixed $id_token = null, mixed $code_challenge = null, mixed $code_challenge_method = null): mixed

This function should be the storage counterpart to getAuthCode().

If storage fails for some reason, we're not currently checking for any sort of success/failure, so you should bail out of the script and provide a descriptive fail message.

Required for OAuth2::GRANT_TYPE_AUTH_CODE.

`$code`	mixed	- Authorization code to be stored.
`$client_id`	mixed	- Client identifier to be stored.
`$user_id`	mixed	- User identifier to be stored.

Return Value:

Client details. The only mandatory key in the array is "redirect_uri". This function MUST return FALSE if the given client does not exist or is invalid. "redirect_uri" can be space-delimited to allow for multiple valid uris. return array( "redirect_uri" => REDIRECT_URI, // REQUIRED redirect_uri registered for the client "client_id" => CLIENT_ID, // OPTIONAL the client id "grant_types" => GRANT_TYPES, // OPTIONAL an array of restricted grant types "user_id" => USER_ID, // OPTIONAL the user identifier associated with this client "scope" => SCOPE, // OPTIONAL the scopes allowed for this client );

checkRestrictedGrantType

Check restricted grant types of corresponding client identifier.

public checkRestrictedGrantType(mixed $client_id, mixed $grant_type): true

If you want to restrict clients to certain grant types, override this function.

getRefreshToken

Grant refresh access tokens.

public getRefreshToken(mixed $refresh_token): \OAuth2\Storage\An

Retrieve the stored data for the given refresh token.

Required for OAuth2::GRANT_TYPE_REFRESH_TOKEN.

Parameters:

Parameter	Type	Description
`$refresh_token`	mixed	Refresh token to be check with.

Return Value:

associative array as below, and NULL if the refresh_token is invalid: - refresh_token: Refresh token identifier. - client_id: Client identifier. - user_id: User identifier. - expires: Expiration unix timestamp, or 0 if the token doesn't expire. - scope: (optional) Scope values in space-separated string.

setRefreshToken

Take the provided refresh token values and store them somewhere.

public setRefreshToken(mixed $refresh_token, mixed $client_id, mixed $user_id, mixed $expires, mixed $scope = null): mixed

This function should be the storage counterpart to getRefreshToken().

If storage fails for some reason, we're not currently checking for any sort of success/failure, so you should bail out of the script and provide a descriptive fail message.

Required for OAuth2::GRANT_TYPE_REFRESH_TOKEN.

Parameters:

Parameter	Type	Description
`$refresh_token`	mixed	Refresh token to be stored.
`$client_id`	mixed	Client identifier to be stored.

unsetRefreshToken

Expire a used refresh token.

public unsetRefreshToken(mixed $refresh_token): mixed

This is not explicitly required in the spec, but is almost implied. After granting a new refresh token, the old one is no longer useful and so should be forcibly expired in the data store so it can't be used again.

If storage fails for some reason, we're not currently checking for any sort of success/failure, so you should bail out of the script and provide a descriptive fail message.

Parameters:
