'/User.Read'; 63 | 64 | if (isset($_GET['code']) && isset($_SESSION['OAuth2.state']) && isset($_GET['state'])) { 65 | if ($_GET['state'] == $_SESSION['OAuth2.state']) { 66 | unset($_SESSION['OAuth2.state']); 67 | 68 | // Try to get an access token (using the authorization code grant) 69 | /** @var AccessToken $token */ 70 | $token = $provider->getAccessToken('authorization_code', [ 71 | 'scope' => $provider->scope, 72 | 'code' => $_GET['code'], 73 | ]); 74 | 75 | // Verify token 76 | // Save it to local server session data 77 | 78 | return $token->getToken(); 79 | } else { 80 | echo 'Invalid state'; 81 | 82 | return null; 83 | } 84 | } else { 85 | // // Check local server's session data for a token 86 | // // and verify if still valid 87 | // /** @var ?AccessToken $token */ 88 | // $token = // token cached in session data, null if not found; 89 | // 90 | // if (isset($token)) { 91 | // $me = $provider->get($provider->getRootMicrosoftGraphUri($token) .

Instead of scopes, you specify the resource which you would like to access - there is a param `$provider->authWithResource` which will automatically populate the `resource` param of request with the value of either `$provider->resource` or `$provider->urlAPI`. This feature is mostly intended for v2.0 endpoint of Azure AD (see more [here](https://docs.microsoft.com/en-us/azure/active-directory/develop/azure-ad-endpoint-comparison#scopes-not-resources)). 124 | 125 | #### Using custom parameters 126 | 127 | With [oauth2-client](https://github.com/thephpleague/oauth2-client) of version 1.3.0 and higher, it is now possible to specify custom parameters for the authorization URL, so you can now make use of options like `prompt`, `login_hint` and similar. See the following example of obtaining an authorization URL which will force the user to reauthenticate: 128 | ```php 129 | $authUrl = $provider->getAuthorizationUrl([ 130 | 'prompt' => 'login' 131 | ]); 132 | ``` 133 | You can find additional parameters [here](https://msdn.microsoft.com/en-us/library/azure/dn645542.aspx). 134 | 135 | #### Using a certificate key pair instead of the shared secret 136 | 137 | - Generate a key pair, e.g. with: 138 | ```bash 139 | openssl genrsa -out private.key 2048 140 | openssl req -new -x509 -key private.key -out publickey.cer -days 365 141 | ``` 142 | - Upload the `publickey.cer` to your app in the Azure portal 143 | - Note the displayed thumbprint for the certificate (it looks like `B4A94A83092455AC4D3AC827F02B61646EAAC43D`) 144 | - Put that thumbprint into the `clientCertificateThumbprint` constructor option 145 | - Put the contents of `private.key` into the `clientCertificatePrivateKey` constructor option 146 | - You can omit the `clientSecret` constructor option 147 | 148 | ### Logging out 149 | If you need to quickly generate a logout URL for the user, you can do following: 150 | ```php 151 | // Assuming you have provider properly initialized. 152 | $post_logout_redirect_uri = 'https://www.msn.com'; // The logout destination after the user is logged out from their account. 153 | $logoutUrl = $provider->getLogoutUrl($post_logout_redirect_uri); 154 | header('Location: '.$logoutUrl); // Redirect the user to the generated URL 155 | ``` 156 | 157 | #### Call on behalf of a token provided by another app 158 | 159 | ```php 160 | // Use token provided by the other app 161 | // Make sure the other app mentioned this app in the scope when requesting the token 162 | $suppliedToken = ''; 163 | 164 | $provider = xxxxx;// Initialize provider 165 | 166 | // Call this to get claims 167 | // $claims = $provider->validateAccessToken($suppliedToken); 168 | 169 | /** @var AccessToken $token */ 170 | $token = $provider->getAccessToken('jwt_bearer', [ 171 | 'scope' => $provider->scope, 172 | 'assertion' => $suppliedToken, 173 | 'requested_token_use' => 'on_behalf_of', 174 | ]); 175 | ``` 176 | 177 | ## Making API Requests 178 | 179 | This library also provides easy interface to make it easier to interact with [Azure Graph API](https://msdn.microsoft.com/en-us/library/azure/hh974476.aspx) and [Microsoft Graph](http://graph.microsoft.io), the following methods are available on `provider` object (it also handles automatic token refresh flow should it be needed during making the request): 180 | 181 | - `get($ref, $accessToken, $headers = [])` 182 | - `post($ref, $body, $accessToken, $headers = [])` 183 | - `put($ref, $body, $accessToken, $headers = [])` 184 | - `delete($ref, $body, $accessToken, $headers = [])` 185 | - `patch($ref, $body, $accessToken, $headers = [])` 186 | - `getObjects($tenant, $ref, $accessToken, $headers = [])` This is used for example for listing large amount of data - where you need to list all users for example - it automatically follows `odata.nextLink` until the end. 187 | - `$tenant` tenant has to be provided since the `odata.nextLink` doesn't contain it. 188 | - `request($method, $ref, $accessToken, $options = [])` See [#36](https://github.com/TheNetworg/oauth2-azure/issues/36) for use case. 189 | 190 | *Please note that if you need to create a custom request, the method getAuthenticatedRequest and getResponse can still be used.* 191 | 192 | ### Variables 193 | - `$ref` The URL reference without the leading `/`, for example `myOrganization/groups` 194 | - `$body` The contents of the request, make has to be either string (so make sure to use `json_encode` to encode the request)s or stream (see [Guzzle HTTP](http://docs.guzzlephp.org/en/latest/request-options.html#body)) 195 | - `$accessToken` The access token object obtained by using `getAccessToken` method 196 | - `$headers` Ability to set custom headers for the request (see [Guzzle HTTP](http://docs.guzzlephp.org/en/latest/request-options.html#headers)) 197 | 198 | ## Resource Owner 199 | With version 1.1.0 and onward, the Resource Owner information is parsed from the JWT passed in `access_token` by Azure Active Directory. It exposes few attributes and one function. 200 | 201 | **Example:** 202 | ```php 203 | $resourceOwner = $provider->getResourceOwner($token); 204 | echo 'Hello, '.$resourceOwner->getFirstName().'!'; 205 | ``` 206 | The exposed attributes and function are: 207 | - `getId()` - Gets user's object id - unique for each user 208 | - `getFirstName()` - Gets user's first name 209 | - `getLastName()` - Gets user's family name/surname 210 | - `getTenantId()` - Gets id of tenant which the user is member of 211 | - `getUpn()` - Gets user's User Principal Name, which can be also used as user's e-mail address 212 | - `claim($name)` - Gets any other claim (specified as `$name`) from the JWT, full list can be found [here](https://azure.microsoft.com/en-us/documentation/articles/active-directory-token-and-claims/) 213 | 214 | ## Microsoft Graph 215 | Calling [Microsoft Graph](http://graph.microsoft.io/) is very simple with this library. After provider initialization simply change the API URL followingly (replace `v1.0` with your desired version): 216 | ```php 217 | // Mention Microsoft Graph scope when initializing the provider 218 | $baseGraphUri = $provider->getRootMicrosoftGraphUri(null); 219 | $provider->scope = 'your scope ' . $baseGraphUri . '/User.Read'; 220 | 221 | // Call a query 222 | $provider->get($provider->getRootMicrosoftGraphUri($token) . '/v1.0/me', $token); 223 | ``` 224 | After that, when requesting access token, refresh token or so, provide the `resource` with value `https://graph.microsoft.com/` in order to be able to make calls to the Graph (see more about `resource` [here](#advanced-flow)). 225 | 226 | ## Protecting your API - *experimental* 227 | With version 1.2.0 you can now use this library to protect your API with Azure Active Directory authentication very easily. The Provider now also exposes `validateAccessToken(string $token)` which lets you pass an access token inside which you for example received in the `Authorization` header of the request on your API. You can use the function followingly (in vanilla PHP): 228 | ```php 229 | // Assuming you have already initialized the $provider 230 | 231 | // Obtain the accessToken - in this case, we are getting it from Authorization header. 232 | // If you're instead using a persisted access token you got from $provider->getAccessToken, 233 | // you'll have to feed its id token to validateAccessToken like so: $provider->validateAccessToken($accessTokenn->getIdToken()); 234 | $headers = getallheaders(); 235 | // Assuming you got the value of Authorization header as "Bearer [the_access_token]" we parse it 236 | $authorization = explode(' ', $headers['Authorization']); 237 | $accessToken = $authorization[1]; 238 | 239 | try { 240 | $claims = $provider->validateAccessToken($accessToken); 241 | } catch (Exception $e) { 242 | // Something happened, handle the error 243 | } 244 | 245 | // The access token is valid, you can now proceed with your code. You can also access the $claims as defined in JWT - for example roles, group memberships etc. 246 | ``` 247 | 248 | You may also need to access some other resource from the API like the Microsoft Graph to get some additional information. In order to do that, there is `urn:ietf:params:oauth:grant-type:jwt-bearer` grant available ([RFC](https://tools.ietf.org/html/draft-jones-oauth-jwt-bearer-03)). An example (assuming you have the code above working and you have the required permissions configured correctly in the Azure AD application): 249 | ```php 250 | $graphAccessToken = $provider->getAccessToken('jwt_bearer', [ 251 | 'resource' => 'https://graph.microsoft.com/v1.0/', 252 | 'assertion' => $accessToken, 253 | 'requested_token_use' => 'on_behalf_of' 254 | ]); 255 | 256 | $me = $provider->get('https://graph.microsoft.com/v1.0/me', $graphAccessToken); 257 | print_r($me); 258 | ``` 259 | Just to make it easier so you don't have to remember entire name for `grant_type` (`urn:ietf:params:oauth:grant-type:jwt-bearer`), you just use short `jwt_bearer` instead. 260 | 261 | ## Azure Active Directory B2C - *experimental* 262 | You can also now very simply make use of [Azure Active Directory B2C](https://azure.microsoft.com/en-us/documentation/articles/active-directory-b2c-reference-oauth-code/). Before authentication, change the endpoints using `pathAuthorize`, `pathToken` and `scope` and additionally specify your [login policy](https://azure.microsoft.com/en-gb/documentation/articles/active-directory-b2c-reference-policies/). **Please note that the B2C support is still experimental and wasn't fully tested.** 263 | ```php 264 | $provider->pathAuthorize = "/oauth2/v2.0/authorize"; 265 | $provider->pathToken = "/oauth2/v2.0/token"; 266 | $provider->scope = ["idtoken"]; 267 | 268 | // Specify custom policy in our authorization URL 269 | $authUrl = $provider->getAuthorizationUrl([ 270 | 'p' => 'b2c_1_siup' 271 | ]); 272 | ``` 273 | 274 | ## Multipurpose refresh tokens - *experimental* 275 | In cause that you need to access multiple resources (like your API and Microsoft Graph), you can use multipurpose [refresh tokens](https://msdn.microsoft.com/en-us/library/azure/dn645538.aspx). Once obtaining a token for first resource, you can simply request another token for different resource like so: 276 | ```php 277 | $accessToken2 = $provider->getAccessToken('refresh_token', [ 278 | 'refresh_token' => $accessToken1->getRefreshToken(), 279 | 'resource' => 'http://urlOfYourSecondResource' 280 | ]); 281 | ``` 282 | At the moment, there is one issue: When you make a call to your API and the token has expired, it will have the value of `$provider->urlAPI` which is obviously wrong for `$accessToken2`. The solution is very simple - set the `$provider->urlAPI` to the resource which you want to call. This issue will be addressed in future release. **Please note that this is experimental and wasn't fully tested.** 283 | 284 | ## Known users 285 | If you are using this library and would like to be listed here, please let us know! 286 | - [TheNetworg/DreamSpark-SSO](https://github.com/thenetworg/dreamspark-sso) 287 | 288 | ## Contributing 289 | We accept contributions via [Pull Requests on Github](https://github.com/thenetworg/oauth2-azure). 290 | 291 | ## Credits 292 | - [Jan Hajek](https://github.com/hajekj) ([TheNetw.org](https://thenetw.org)) 293 | - [Vittorio Bertocci](https://github.com/vibronet) (Microsoft) 294 | - Thanks for the splendid support while implementing #16 295 | - [Martin Cetkovský](https://github.com/mcetkovsky) ([cetkovsky.eu](https://www.cetkovsky.eu)] 296 | - [All Contributors](https://github.com/thenetworg/oauth2-azure/contributors) 297 | 298 | ## Support 299 | If you find a bug or encounter any issue or have a problem/question with this library please create a [new issue](https://github.com/TheNetworg/oauth2-azure/issues). 300 | 301 | ## License 302 | The MIT License (MIT).
