Hi,
Does FPC support annotations yet?
So in the future (or hopefully now), we could create something like what
many Java frameworks allow. Simply annotate a plain class to do the
magic for you - a massive reduction in boilerplate code. So we could end
up with a RESTful resource/controller as follows:
@Path('/troopers')
@Produces('application/json')
TStormtrooperResource = class(TObject)
public
@Path('/{id}')
@GET
function GetStormtrooper(@PathParam('id') id: string): TStormtrooper;
@POST
function CreateTrooper(trooper: TStormTrooper): TStormtrooper;
end;
function TStormTrooperResource.GetStromtrooper(const id: string):
TStormtrooper;
begin
result := SomeDataAccessLayer.GetStormtrooper(id);
end;
function TStormTrooperResource.CreateTrooper(trooper: TStormTrooper):
TStormtrooper;
begin
result := SomeDataAccessLayer.AddTrooper(trooper);
end;
So with a web browser or rest client, if you visit the endpoint
'/troopers/7' it will return a TStormtrooper object serialized as JSON
output. And also a POST to the endpoint '/troopers' will add a
Stormtrooper to your database.
If you wanted XML instead of JSON, simply changes the @Produces annotation.
