post multipart data

I need to send a zip file to a rest service as http(s) post with content-type multipart/form-data. The rest service will return json data to indicate success/failure.

I found this forum post: http://synopse.info/forum/viewtopic.php?id=2366 but is there any documentation on how to use it or perhaps a small example?

Re: post multipart data

In end-user code, you should use TSQLRestServerURIContext.InputAsMultiPart in a method-based service.
See http://synopse.info/files/html/api-1.18 … C_436B0FC2

Re: post multipart data

Thanks but I don't understand how this relates to the TWinHttp.Post request that I'd like to send:

  SetLength(MultiPart, 1);
  MultiPart[0].Name := 'file';
  MultiPart[0].FileName := ExtractFileName(Filename);
  MultiPart[0].ContentType := 'application/octet-stream';
  MultiPart[0].Encoding := 'UTF8';
  MultiPart[0].Content := Body;

  ctx := TSQLRestServerURIContext.Create;
  ctx.InputAsMultiPart(MultiPart);

  // what to do to send with TWinHttp.Post ?

Re: post multipart data

Oh - I did not understand your exact question.
I though your were talking about the server part.

There is no multi-part mime encoding for the client yet in SynCrtSock.pas.
So you would have to use Indy or Synapse to compute the body, then send it via TWinHttp.Post().
