Ajax POST请求为空

Question

I tried to upload files with Ajax. But POST request is empty.

var fd = new FormData();
fd.append('file', files[0].name);
alert(files[0].name);
$("#form_upload").submit();
$.ajax({
    method: "POST",
    url: "/dropupload/",
    contentType: false,
    processData: false,
    data: fd,
    success: function(data) {
        waitforprocess();
    },
    complete: function(data){
        alert(formdata.size)
    },
    error: function(){
        allert("error")
    }
}); 

in views POST is emty

def post(request):
    q = request.POST.get("file")

q = None

Why POST is empty?

Answer 1

Try serializing the form data instead of creating a new FormData object. Like:

var $form = $("#form_upload").find('form');
var fd = $form.serialize();
// ...
