=== Authenticate API
|
|
|
|
[id="{upid}-{api}-sync"]
|
|
==== Execution
|
|
|
|
Authenticating and retrieving information about a user can be performed
|
|
using the `security().authenticate()` method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-execute]
|
|
--------------------------------------------------
|
|
|
|
This method does not require a request object. The client waits for the
|
|
+{response}+ to be returned before continuing with code execution.
|
|
|
|
[id="{upid}-{api}-response"]
|
|
==== Response
|
|
|
|
The returned +{response}+ contains four fields. The `user` field
|
|
, accessed with `getUser`, contains all the information about this
|
|
authenticated user. The field `enabled`, tells if this user is actually
|
|
usable or has been temporarily deactivated. The field `authentication_realm`,
|
|
accessed with `getAuthenticationRealm` contains the name and type of the
|
|
Realm that has authenticated the user and the field `lookup_realm`,
|
|
accessed with `getLookupRealm` contains the name and type of the Realm where
|
|
the user information were retrieved from.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-response]
|
|
--------------------------------------------------
|
|
<1> `getUser` retrieves the `User` instance containing the information,
|
|
see {javadoc-client}/security/user/User.html.
|
|
<2> `enabled` tells if this user is usable or is deactivated.
|
|
<3> `getAuthenticationRealm().getName()` retrieves the name of the realm that authenticated the user.
|
|
<4> `getAuthenticationRealm().getType()` retrieves the type of the realm that authenticated the user.
|
|
<5> `getLookupRealm().getName()` retrieves the name of the realm from where the user information is looked up.
|
|
<6> `getLookupRealm().getType()` retrieves the type of the realm from where the user information is looked up.
|
|
|
|
[id="{upid}-{api}-async"]
|
|
==== Asynchronous Execution
|
|
|
|
This request can also be executed asynchronously:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `ActionListener` to use when the execution completes. This method does
|
|
not require a request object.
|
|
|
|
The asynchronous method does not block and returns immediately. Once the request
|
|
has completed the `ActionListener` is called back using the `onResponse` method
|
|
if the execution completed successfully or using the `onFailure` method if
|
|
it failed.
|
|
|
|
A typical listener for a +{response}+ looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-execute-listener]
|
|
--------------------------------------------------
|
|
<1> Called when the execution completed successfully. The response is
|
|
provided as an argument.
|
|
<2> Called in case of a failure. The exception is provided as an argument.
