Usage

AutoFileSender needs 4 params.

1. server ip
2. server path
3. server port
4. directory path you want to watch

AutoFileSender con("127.0.0.1", "/upload/","8000","/home/horoyoii/Desktop");

#include"AutoFileSender.h"

int main(int argc, char* argv[]){

    AutoFileSender con("127.0.0.1", "/upload/","8000","/home/horoyoii/Desktop");
    con.run();

    cout<<"not printed here"<<endl;

    return 0;
}

server side may look like (In python Django)

  @csrf_exempt
  def upload_file(req):
    if req.method == 'POST':                       
         if 'file' in req.FILES:
              file = req.FILES['file']
              filename = file._name
              data = file.read()
              decoded = base64.b64decode(data)
              
              f = open("./upload/"+filename, "wb")
              f.write(decoded)
              f.close()
              return HttpResponse('File Uploaded')
         else:
              return HttpResponse("no file field")

Features

• Simple C++ API
• Runs on Linux platform
• Binary data are encoded by base64
• does not detect .swp or .swx files

Stuff it doesn't do

• It's Linux focused and probably won't work on ohter systmes.
• the file size is limited to 10MB.
• it doesn't detect the directory recursively.
