The identity handler ties directly with the wf:user
functions, the default approach is to simply store the user information into a specific session variable.
init(Config, State)
Initialize the handler
{ok, NewState}
finish(Config, State)
Clean up the handler
{ok, NewState}
get_user(Config, State)
Retrieve the previously stored user information.
set_user(User, Config, State)
Set the user information
User
- Free-form user information. Can be any erlang term: a username, user ID, tuple, proplist, Erlang record, etc..
/Return Value/ - {ok, NewState}
clear(Config, State)
Clear the user information.
Here is the complete text of the default identity handler, which uses simply stores the data in sessions.
-module (default_identity_handler).
-behaviour (identity_handler).
-export ([
init/2,
finish/2,
get_user/2,
set_user/3,
clear/2
]).
-define(KEY, {default_identity_handler, user}).
init(_Config, State) ->
{ok, State}.
finish(_Config, State) ->
{ok, State}.
get_user(_Config, _State) ->
wf:session(?KEY).
set_user(User, _Config, State) ->
wf:session(?KEY, User),
{ok, State}.
clear(_Config, State) ->
wf:session(?KEY, undefined),
{ok, State}.
