upload file to the server for indexing in the server using browser UNIGUI application

[mazluta 1]

I have a document management system (DMS) written in Delphi UNIGUI.

I have a scanning system with many capabilities written in Delphi DESKTOP.

I want to scan with the DeskTop application and when finished send the scanned file to the server (Unigui) to perform the filing on the server.
The server should receive the file, save it in the temporary area and pop up a filing screen.

What is the best way to do it?

I'm not sure there's a "best" way; there are many options and depending on your time, abilities, security requirements, and possibly other factors, one solution may work better than others. Here are a few suggestions and you can shoot down which ones that won't work for some reason or other:

• Use a file-sync service (DropBox, pCloud, etc.) then your desktop app can simply save a file to a pre-selected folder and a few moments later it will be synchronized to your server. This would be the quickest and easiest to implement but you may not trust a third-party service.
• Set up FTP/SFTP on your server with a custom login; then implement SFTP in your desktop app to send the file to that SFTP account.
• I don't know UniGUI that well but if there's an easy way to provide a URL for HTTP-POST messages, then add that to your server app; your desktop app would then simply send the file in an HTTP-POST message to that URL.
• You could also write your own custom messaging service, the server side would listen on a specific port and your desktop would send files to that port. But why reinvent FTP?

There are too few informations to do a proposal:

 

- they should work inside a LAN, a WLAN, Internet ?

- they should work inside an office, a complex structure ?

- how many processes will there be? 100 per seconds, 100 per hours ?

-etc ...

Hi David.

yes, you right.

Since the Server (UNIGUI) is always running i thought to use it as "FTP". 

 

on the Desktop App

 

var
  HTTP: TIdHTTP;
  FormData: TIdMultipartFormDataStream;
  url : string;
  FilePath : string;
  ResultInt : Int64;
begin
  Try
    HTTP := TIdHTTP.Create(nil);
    FormData := TIdMultipartFormDataStream.Create;
    try
      FilePath := 'c:\a\M1.pdf';
      URL := PrmUrlAddress + ':' + IntToStr(PrmUrlPort) + '/Indexing';
      ResultInt := GetUniqueNumber;
      JustWriteToLog('url=' + url);
      JustWriteToLog('ResultInt=' + IntToStr(ResultInt));
      FormData.AddFile('file', FilePath, 'application/octet-stream'); // 'file' is the form field name expected by the server
      FormData.AddFormField('UniqueName', IntToStr(ResultInt));

      HTTP.Post(URL, FormData); // URL is the endpoint, e.g., http://yourserver:port/upload
      ShowMessage('File uploaded successfully - Status Code = ' + IntToStr(HTTP.ResponseCode));
      ShowMessage('Response Text = ' + HTTP.ResponseText);
    except
      on E: Exception do
        ShowMessage('Failed to upload file: ' + E.Message);
    end;
  Finally
    FormData.Free;
    HTTP.Free;
  End;
 

and on the server (UNIGUI)

 

Var
  FileStream: TFileStream;
  SavePath  : string;
  FileFirstName : String;
  FormData: TIdMultiPartFormDataStream;
begin
  if ARequestInfo.URI = '/Indexing' then
  begin
    FormData := TIdMultiPartFormDataStream.Create;
    FileFirstName := The Extra PARAM Field
    SavePath := 'C:\a\' + FileFirstName + '.pdf';
    FileStream := TFileStream.Create(SavePath, fmCreate);
    try
      // Copy the incoming data to the file stream
      FileStream.CopyFrom(ARequestInfo.PostStream, ARequestInfo.PostStream.Size);
    finally
      FileStream.Free;
    end;
    AResponseInfo.ResponseText := 'File Saved OK';
    Handled := True;
  end;
end;

 

then after getting 200 status from the server,

send another one with the unique no and go to indexing process.

yes. sorry.

office - internet - cloud server.

the desktop will be installed in any of the clients

10-50 per day.

5 users.

 

since i new to web development i would like to hear what the masters idea

I think you are in the right way. Think about HTTPS transfer and may be a simple login (sending username and password for example).

this is the solution
