How can I send a file created by javascript, to server and then handle it by django, for emailing?

My javascript code:

function PrepareEmailPrescription() {

    doc = PreparePrescriptionPDF()

    var pdf = doc.output();   

    var fd = new FormData();    

    fd.append( 'file', pdf );

    $.ajax({

        url: `/clinic/${cliniclabel}/prescription/sendemail/patient/${patient_id}`,

        data: fd,

        processData: false,

        contentType: false,

        type: 'POST',

        success: function(data){

        alert(data);

        }

    });  

}

Here, PreparePrescriptionPDF is a function which generated a pdf file with pdfjs.

On the django server, I have:

def SendPrescriptionbyMail(request, cliniclabel, patient_id):

    # print(request.body)

    print(request.FILES)

    print(request.FILES['file'])

    return HttpResponse('Successfully sent email')

I am getting the following response from django:

[14/Nov/2018 15:59:18] "GET /clinic/medicines HTTP/1.1" 200 8389

<MultiValueDict: {}>

    });  

}
