|
||
This package provides Apple ID OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client). | ||
|
||
## Before You Begin | ||
|
||
Here you can find the official Apple documentation: | ||
https://developer.apple.com/documentation/signinwithapplerestapi | ||
|
||
If you request email address or name please note that you'll get this only in your first login. | ||
When you log in a second time you will only get the user id - nothing more. | ||
Maybe Apple changes this sometime. | ||
|
||
## Installation | ||
|
||
To install, use composer: | ||
|
||
``` | ||
composer require patrickbussmann/oauth2-apple | ||
``` | ||
|
||
## Usage | ||
|
||
Usage is the same as The League's OAuth client, using `\League\OAuth2\Client\Provider\Apple` as the provider. | ||
|
||
### Authorization Code Flow | ||
|
||
```php | ||
// $leeway is needed for clock skew | ||
Firebase\JWT\JWT::$leeway = 60; | ||
|
||
$provider = new League\OAuth2\Client\Provider\Apple([ | ||
'clientId' => '{apple-client-id}', | ||
'teamId' => '{apple-team-id}', // 1A234BFK46 https://developer.apple.com/account/#/membership/ (Team ID) | ||
'keyFileId' => '{apple-key-file-id}', // 1ABC6523AA https://developer.apple.com/account/resources/authkeys/list (Key ID) | ||
'keyFilePath' => '{apple-key-file-path}', // __DIR__ . '/AuthKey_1ABC6523AA.p8' -> Download key above | ||
'redirectUri' => 'https://example.com/callback-url', | ||
]); | ||
|
||
if (!isset($_POST['code'])) { | ||
|
||
// If we don't have an authorization code then get one | ||
$authUrl = $provider->getAuthorizationUrl(); | ||
$_SESSION['oauth2state'] = $provider->getState(); | ||
header('Location: '.$authUrl); | ||
exit; | ||
|
||
// Check given state against previously stored one to mitigate CSRF attack | ||
} elseif (empty($_POST['state']) || ($_POST['state'] !== $_SESSION['oauth2state'])) { | ||
|
||
unset($_SESSION['oauth2state']); | ||
exit('Invalid state'); | ||
|
||
} else { | ||
|
||
// Try to get an access token (using the authorization code grant) | ||
/** @var AppleAccessToken $token */ | ||
$token = $provider->getAccessToken('authorization_code', [ | ||
'code' => $_POST['code'] | ||
]); | ||
|
||
// Optional: Now you have a token you can look up a users profile data | ||
// Important: The most details are only visible in the very first login! | ||
// In the second and third and ... ones you'll only get the identifier of the user! | ||
try { | ||
|
||
// We got an access token, let's now get the user's details | ||
$user = $provider->getResourceOwner($token); | ||
|
||
// Use these details to create a new profile | ||
printf('Hello %s!', $user->getFirstName()); | ||
|
||
} catch (Exception $e) { | ||
|
||
// Failed to get user details | ||
exit(':-('); | ||
} | ||
|
||
// Use this to interact with an API on the users behalf | ||
echo $token->getToken(); | ||
} | ||
``` | ||
|
||
### Revoke Code Flow | ||
|
||
```php | ||
// $leeway is needed for clock skew | ||
Firebase\JWT\JWT::$leeway = 60; | ||
|
||
$provider = new League\OAuth2\Client\Provider\Apple([ | ||
'clientId' => '{apple-client-id}', | ||
'teamId' => '{apple-team-id}', // 1A234BFK46 https://developer.apple.com/account/#/membership/ (Team ID) | ||
'keyFileId' => '{apple-key-file-id}', // 1ABC6523AA https://developer.apple.com/account/resources/authkeys/list (Key ID) | ||
'keyFilePath' => '{apple-key-file-path}', // __DIR__ . '/AuthKey_1ABC6523AA.p8' -> Download key above | ||
'redirectUri' => 'https://example.com/callback-url', | ||
]); | ||
|
||
$token = $token->getToken(); // Use the token of "Authorization Code Flow" which you saved somewhere for the user | ||
|
||
|
||
try { | ||
$provider->revokeAccessToken($token /*, 'access_token' or 'refresh_token' */); | ||
// Successfully revoked the token! | ||
|
||
} catch (Exception $e) { | ||
|
||
// Failed to revoke | ||
exit(':-('); | ||
} | ||
``` | ||
|
||
### Managing Scopes | ||
|
||
When creating your Apple authorization URL, you can specify the state and scopes your application may authorize. | ||
|
||
```php | ||
$options = [ | ||
'state' => 'OPTIONAL_CUSTOM_CONFIGURED_STATE', | ||
// Scopes: https://developer.apple.com/documentation/authenticationservices/asauthorizationscope | ||
'scope' => ['name', 'email'] // array or string | ||
]; | ||
|
||
$authorizationUrl = $provider->getAuthorizationUrl($options); | ||
``` | ||
If neither are defined, the provider will utilize internal defaults. | ||
|
||
At the time of authoring this documentation, the following scopes are available. | ||
|
||
- name (default) | ||
- email (default) | ||
|
||
Please note that you will get this informations only at the first log in of the user! | ||
In the following log ins you'll get only the user id! | ||
|
||
If you only want to get the user id, you can set the `scope` as ` `, then change all the `$_POST` to `$_GET`. | ||
|
||
### Refresh Tokens | ||
|
||
If your access token expires you can refresh them with the refresh token. | ||
|
||
``` | ||
$refreshToken = $token->getRefreshToken(); | ||
$refreshTokenExpiration = $token->getRefreshTokenExpires(); | ||
``` | ||
|
||
## Testing | ||

||
