== Evaluation API
|
|
|
|
When writing rule-based policies such as when you are using Javascript or JBoss Drools, Keycloak provides an *Evaluation API* from where you
|
|
can obtain useful information.
|
|
|
|
This API consists of a few interfaces that provides you access to information such as:
|
|
|
|
* Information about the identity asking for a permission. Here you can obtain the identity identifier (eg.: username) or any other claim/attribute about it.
|
|
* Information about the runtime environment and any other attribute associated with the execution context.
|
|
|
|
The main interface is *org.keycloak.authorization.policy.evaluation.Evaluation*, which defines the following contract:
|
|
|
|
```java
|
|
public interface Evaluation {
|
|
|
|
/**
|
|
* Returns the {@link ResourcePermission} to be evaluated.
|
|
*
|
|
* @return the permission to be evaluated
|
|
*/
|
|
ResourcePermission getPermission();
|
|
|
|
/**
|
|
* Returns the {@link EvaluationContext}. Which provides access to the whole evaluation runtime context.
|
|
*
|
|
* @return the evaluation context
|
|
*/
|
|
EvaluationContext getContext();
|
|
|
|
/**
|
|
* Grants the requested permission to the caller.
|
|
*/
|
|
void grant();
|
|
|
|
/**
|
|
* Denies the requested permission.
|
|
*/
|
|
void deny();
|
|
}
|
|
```
|
|
|
|
For full instructions on using the Evaluation API refer to JavaDocs. |
