I have service interface method declared like this
IPriceInterfaces = interface( IInvokable)
['{D330D32F-6975-4385-8808-C4A3B08CA52D}']
function updateprices(xlsx: TStream):TInterfaceresult;
My server side code works nicely (tested with postman)
Should TXdataClient support this ?
Looks like it doesn't .
lPriceMethod := xClient.Service;
ms := TMemoryStream.Create;
ms.LoadFromFile(edtExcelName.FileName);
r := lPriceMethod.updateprices(ms);
It should.
What is the error you are getting?
Maybe you need to set
ms.Position := 0;
before calling the service?
It was complaining about content-type, it was not provided. Then I added that, It complained about "Boundary not specified in multipart header"
Actually first error was "invalid mediatype, expected multipart/*, actual "
And I had position:=0 .. removed it with some other code.
I'm not sure how is your service implementation? Are you treating the stream as multipart content?
