 # OpenID Support in Play

-OpenID is a protocol for users to access several services with a single account. As a web developer, you can use OpenID to offer users a way to login with an account they already have (their [Google account](https://developers.google.com/accounts/docs/OpenID) for example). In the enterprise, you can use OpenID to connect to a company's SSO server if it supports it.

-## OpenID in Play Framework
+## Usage
+
+To use OpenID, first add `javaWs`  to your `build.sbt` file:
+
+'''scala
+libraryDependencies ++= Seq(
+  javaWs
+)
+'''
+
+Now any controller or component that wants to use OpenID will have to declare a dependency on the [OpenIdClient](api/java/play/libs/openid/OpenIdClient.html).
+
+## OpenID in Play

 The OpenID API has two important functions:

-* `OpenID.redirectURL` calculates the URL where you should redirect the user. It involves fetching the user's OpenID page, this is why it returns a `Promise<String>` rather than a `String`. If the OpenID is invalid, an exception will be thrown.
-* `OpenID.verifiedId` inspects the current request to establish the user information, including his verified OpenID. It will do a call to the OpenID server to check the authenticity of the information, this is why it returns a `Promise<UserInfo>` rather than just `UserInfo`. If the information is not correct or if the server check is false (for example if the redirect URL has been forged), the returned `Promise` will be a `Thrown`.
+* `OpenIdClient.redirectURL` calculates the URL where you should redirect the user. It involves fetching the user's OpenID page asynchronously, this is why it returns a `Promise<String>`. If the OpenID is invalid, the returned `Promise` will be a `Thrown`.
+* `OpenIdClient.verifiedId` inspects the current request to establish the user information, including his verified OpenID. It will do a call to the OpenID server asynchronously to check the authenticity of the information, returning a promise of [UserInfo](api/java/play/libs/openid/UserInfo.html). If the information is not correct or if the server check is false (for example if the redirect URL has been forged), the returned `Promise` will be a `Thrown`.
+
+If the `Promise` fails, you can define a fallback, which redirects back the user to the login page or return a `BadRequest`.
+
+### Example
+
+`conf/routes`:
+
+@[ws-openid-routes](code/javaguide.ws.routes)
+
+controller:
+
+@[ws-openid-controller](code/javaguide/ws/controllers/OpenIDController.java)

-In any case, you should catch exceptions and if one is thrown redirect back the user to the login page with relevant information.

 ## Extended Attributes

-The OpenID of a user gives you his identity. The protocol also support getting [extended attributes](http://openid.net/specs/openid-attribute-exchange-1_0.html) such as the email address, the first name, the last name...

-You may request from the OpenID server *optional* attributes and/or *required* attributes. Asking for required attributes means the user can not login to your service if he doesn't provides them.

 Extended attributes are requested in the redirect URL:

-'''
-Map<String, String> attributes = new HashMap<String, String>();
-attributes.put("email", "http://schema.openid.net/contact/email");
-OpenID.redirectURL(
-  openid, 
-  routes.Application.openIDCallback.absoluteURL(request()), 
-  attributes
-);
-'''
+@[ws-openid-extended-attributes](code/javaguide/ws/controllers/OpenIDController.java)

 Attributes will then be available in the `UserInfo` provided by the OpenID server.
