Hello I have the following code:
Code: [Select] PeticionHttp.RequestHeaders.Clear;
  PeticionHttp.AddHeader('Content-Type', 'application/x-www-form-
urlencoded;v=2.0');
  PeticionHttp.AddHeader('Accept', 'application/hal+json;v=2.0');
  Respuesta := TStringList.Create();
  BodyText :=
'resources=1';//&1=/rw/iosystem/signals/ethernet/board1/do0&1-P=0';
  PeticionHttp.RequestBody.WriteAnsiString('resources:1');
  PeticionHttp.RequestBody.WriteAnsiString(
    '1=/rw/iosystem/signals/ethernet/board1/do0;state');
  PeticionHttp.RequestBody.WriteAnsiString('1-P=0');
  PeticionHttp.RequestBody.Position:=0;
  PeticionHttp.Post('https://localhost:80/subscription', Respuesta); 
        
I got a access violation in this line:
Code:
[Select]PeticionHttp.RequestBody.WriteAnsiString('resources=1'); 

I using Lazarus 3.0 and FPC 3.3.1 Trunc

Any idea?

Thanks

Hello, I found the problem.
I missed this line:
Code: [Select] 
PeticionHttp.RequestBody:=TRawByteStringStream.Create;
