How to send an array of string?

Remoting SDK

Hi

Another small question.
This is my implementation method at server:

[ROService(__ServiceName, __ServiceID)]
  TautenticacaoService = class(TRORemoteDataModule)
     public
     [ROServiceMethod]
     function Login(const aUserID: Unicodestring; const interfaces: array of string ): Unicodestring;

This is what RO generated:

IautenticacaoService = interface(IROService)
  ['{54485C27-740F-4C83-B73B-0783EDAF86D9}']
    function Login(const aUserID: UnicodeString; const interfaces: UnicodeString): UnicodeString;
 end;

Note that it translated array of string into unicodeString

This is my client code (or how I want to send it to server):

...
FConexaoAutenticacao.Login('MARCOS',[EID_LogEvents]);
...

It complains that ‘ordinal type required’, so How can I send and array of string to server?

Hi,

You can use TArray<UnicodeString>

note: You can launch Service Builder (Windows) and generate files in it. it can be helpful:

Hi
When I use TArray:

[ROService(__ServiceName, __ServiceID)]
  TautenticacaoService = class(TRORemoteDataModule)
    procedure RORemoteDataModuleCreate(Sender: TObject);
  private
  public
    [ROServiceMethod]
    function Login(const aUserID: Unicodestring; const interfaces: TArray<UnicodeString> ): Unicodestring;

It generates:

 IautenticacaoService = interface(IROService)
  ['{54485C27-740F-4C83-B73B-0783EDAF86D9}']
    function Login(const aUserID: UnicodeString; const interfaces: TArray_System_string_): UnicodeString;

Which does not compile as it doesn’t know this type TArray_System_string_

I know how to solve it in a hard way: declare a type of array of string as a TROComplexType and so on but I think I am doing some mistake here and there is a simple way to do that…

Hi,

sorry, correct one is TROArray<UnicodeString>.

SB generates this case as

  MyStringArray = class(TROArray<UnicodeString>)
  end;

  INewService = interface(IROService)
  ['{59acf55f-ee19-4ddf-a5a4-203a237906ef}']
    procedure NewMethod(const NewParam: MyStringArray);
  end;
