Plugin entry points¶

Entry point based on PATH_INFO

Plugins can declare unauthRoutes/authRoutes during initialization (= /path/info). Methods declared in this way must be declared in the plugin class. They will be called with $req argument. $req is the HTTP request. (See Lemonldap::NG::Portal::Main::Request). These methods must return a valid PSGI response. You can also use sendJSONresponse() or sendHtml() methods (see Lemonldap::NG::Common::PSGI).

Example:

  sub init {
      my ($self) = @_;
      $self->addUnauthRoute( mypath => 'hello', [ 'GET', 'PUT' ] );
      $self->addAuthRoute( mypath => 'welcome', [ 'GET', 'PUT' ] );
      return 1;
  }
  sub hello {
      my ($self, $req) = @_;
      ...
      return $self->p->sendJSONresponse($req, { hello => 1 });
  }
  sub welcome {
      my ($self, $req) = @_;
      ...
      return $self->p->sendHtml($req, 'template', params => { WELLCOME => 1 });
  }

If you want to get a "protected application" behavior, you can use addAuthRouteWithRedirect. This methods calls addAuthRoute with given arguments and build a "unAuth" route that build a redirection after authentication.

Entry point in auth process

A plugin which wants to be inserted in authentication process has to declare constants set with method name to run. Following entry points are available.

"beforeAuth": method called before authentication process

"betweenAuthAndData": method called after authentication and before setting "sessionInfo" provisionning

"afterData": method called after "sessionInfo" provisionning (macros, groups,...). This entry point is called after 'storeHistory' if login process fails and before 'validSession' if succeeds.

"endAuth": method called when session is validated (after cookie build)

"authCancel": method called when user click on "cancel" during auth process

"forAuthUser": method called for already authenticated users

"beforeLogout": method called before logout

Note: methods inserted so must return a PE_* constant. See Lemonldap::NG::Portal::Main::Constants.

Advanced entry points

These entry points are not stored in "$req->step" but launched on the fly:

"afterSub": hash ref that give methods to call after given main method is called. Example:

  use constant afterSub => {
      getUser => 'mysub',
  }
  sub mysub {
      my ( $self ,$req ) = @_;
      # Do something
      return PE_OK;
  }
    

"aroundSub": hash ref that give methods to call instead of given main method. Example:

  use constant aroundSub => {
      getUser => 'mysub',
  };
  sub mysub {
      my ( $self, $sub, $req ) = @_;
      # Do something before
      my $ret = $sub->($req);
      # Do something after
      return $ret;
  }
    

Do not launch "getUser" but use the given $sub. This permits multiple plugins to use "aroundSub" in the same time.

"hook": hash ref that gives methods to call when a hook is triggered in the LemonLDAP::NG code. Example:

  use constant hook => {
      oidcGenerateIDToken          => 'addClaimToIDToken'
  };
  sub addClaimToIDToken {
    my ( $self, $req, $payload, $rp ) = @_;
    $payload->{"id_token_hook"} = 1;
    return PE_OK;
  }
