XML Parsing error: no root element found (empty content) Django

Question

I am using ajax to connect to a view in my web application.

  $.ajax({
        url: url,
        type: 'PATCH',
        success: function() {
          var d = new Date();
          img = e.target.parentElement.parentElement.getElementsByTagName('img')[0];
          if (img.src.includes("?")){
            img.src = img.src.split("?")[0] + '?' + d.getTime();
          } else {
            img.src = img.src + '?' + d.getTime();
          }

        },
    });

When I click on the button that triggers this, everything works, but I get an XML Parsing error . According to the other questions on stack exchange, this might be beacuse of an empty content. When I use the firefox developer tools, the content of the reverse of the concerned view is indeed empty, because of which, I think, firefox interprets it as an xml. My problem is, that I do not know how to fill the content. In my view, I changed return Response(status=200) to return Response(status=200, content_type='image/jpeg') , because the view does something to an image. But still the content seems to stay empty and I still get the error. I don't know how else to alter the content type than by specifying it in the response. I only get this error in firefox, not in chrome.

Answer 1

结果我只需要将content_type设置为text/html ...

Answer 2

The server response is missing header Content-Type . So the JavaScript 'success' handler cannot parse correctly the response body.
