How get internet filename

Question

Hi
I using following code to get a file information from url, but GetFileName() method not return pure filename! it just returns part of url including trailing numbers!

CInternetSession sess;
CHttpFile* pfile = (CHttpFile*)sess.OpenURL(_T("https://dl2.soft98.ir/soft/s/Solid.PDF.Tools.10.1.12248.5132.rar?1629176293"), 1, INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_RELOAD);

        if (pfile)
        {
            TRACE0("ok\n");
            TRACE1("Filename: %s\n", pfile->GetFileName()); // output is: Solid.PDF.Tools.10.1.12248.5132.rar?1629176293

            DWORD dw;
            pfile->QueryInfo(HTTP_QUERY_CONTENT_LENGTH, dw);
            TRACE1("File lenght: %u\n", dw);

            pfile->Close();
            delete pfile;
        }

        sess.Close();

Answer 1

I think that you can exclude it:

CString example = _T("Solid.PDF.Tools.10.1.12248.5132.rar?1629176293");
int i = example.FindOneOf( _T("?#") );
CString filename = i >= 0 ? example.Left( i ) : example;

Answer 2

According to your description, I wonder if you want to get the filename from the URL and the filename is not contained in the URL? If so, you couldn't get internet filename via GetFileName() method

As far as I'm concerned you could inspect the Content-Disposition response header using an HTTP request to get the filename.
