Middlewares e Guards

In Nidus, middlewares are defined per route via RouteModule('/path', TModule, [TMiddleware...]).

The contract is IRouteMiddleware:

• Before(ARoute): runs before module resolution (can adjust route data)
• Call(AReq): runs during the request (if it returns False, Nidus raises EUnauthorizedException)
• After(ARoute): runs after flow completion (finalization hook)

Example

unit App.Module;

interface

uses
  Nidus.Module,
  Nidus.Route.Abstract,
  Nidus.Request,
  NFe.Module;

type
  TAuthGuard = class(TRouteMiddleware)
  public
    function Call(const AReq: IRouteRequest): Boolean; override;
  end;

  TAppModule = class(TModule)
  public
    function Routes: TRoutes; override;
  end;

implementation

function TAuthGuard.Call(const AReq: IRouteRequest): Boolean;
begin
  Result := (AReq.Username = 'user') and (AReq.Password = '123456');
end;

function TAppModule.Routes: TRoutes;
begin
  Result := [
    RouteModule('/nfe/:id', TNFeModule, [TAuthGuard])
  ];
end;

end.
