Consume Webservice in SOAP with HTTPRIO in DELPHI

Question

I’m having a little trouble with a request via webservice/Soap. I’m trying to feed a function of a WSDL of Vtex through the Delphi and it always returns to me that a value has not been filled in.

Code of my function Insert Field

function TIntegracaoVtex.InserirCampo : Boolean;
var
  funcao : ProductEspecificationInsertByFieldId;
  funcaoResposta: ProductEspecificationInsertByFieldIdResponse;
  valor  : arrayOfString;
begin
  Result := False;
  try
  funcao := ProductEspecificationInsertByFieldId.Create;

  SetLength(valor, 1);
  valor[0]  := '16GB';

  funcao.idProduct   := 11;
  funcao.fieldId     := 23;
  funcao.fieldValues := valor;


  funcaoResposta := ProductEspecificationInsertByFieldIdResponse.Create;
  servico := GetIService(False, 'http://webservice-'+loja+'.vtexcommerce.com.br/AdminWebService/Service.svc', HTTPRIO1);
  servico.ProductEspecificationInsertByFieldId(funcao);

  funcaoResposta := servico.ProductEspecificationInsertByFieldId(funcao);

  Result := True;
  except
    Result := False;
  end;

Webservice function in SOAP, imported from environment VTEX

function  ProductEspecificationInsertByFieldId(const parameters: ProductEspecificationInsertByFieldId): ProductEspecificationInsertByFieldIdResponse; stdcall;

Class received as parameter to feed the function

ProductEspecificationInsertByFieldId = class(TRemotable)
  private
    FidProduct: Integer;
    FidProduct_Specified: boolean;
    FfieldId: Integer;
    FfieldId_Specified: boolean;
    FfieldValues: ArrayOfstring;
    FfieldValues_Specified: boolean;
    procedure SetidProduct(Index: Integer; const AInteger: Integer);
    function  idProduct_Specified(Index: Integer): boolean;
    procedure SetfieldId(Index: Integer; const AInteger: Integer);
    function  fieldId_Specified(Index: Integer): boolean;
    procedure SetfieldValues(Index: Integer; const AArrayOfstring: ArrayOfstring);
    function  fieldValues_Specified(Index: Integer): boolean;
  public
    constructor Create; override;
  published
    property idProduct:   Integer        Index (IS_OPTN) read FidProduct write SetidProduct stored idProduct_Specified;
    property fieldId:     Integer        Index (IS_OPTN) read FfieldId write SetfieldId stored fieldId_Specified;
    property fieldValues: ArrayOfstring  Index (IS_OPTN or IS_NLBL) read FfieldValues write SetfieldValues stored fieldValues_Specified;
  end;

Answer 1

In my VTEX integration, I use as follows:

var
  objProduto: ProductInsertUpdate;

begin
    objProduto := ProductInsertUpdate.Create;
    objProduto.productVO := ProductDTO2.Create;

    with objProduto.productVO do
    begin
        Id := 23;
        // ... demais dados
    end;

    GetIService.ProductInsertUpdate(objProduto);
end;

Try something with the model above.
