一.FileResponse

def file_download(request, id):
    fileObj = ChangeRequestFile.objects.get(pk=id)
    file_path = fileObj.file.file
    file = open(str(file_path), 'rb')
    response = FileResponse(file)
    response['Content-Type'] = 'application/octet-stream'
    response['Content-Disposition'] = 'attachment;filename="%s"' % urlquote(fileObj.filename)
    return

二.FileWrapper+FileResponse

def file_download(request, id):
    file = ChangeRequestFile.objects.get(pk=id)
    wrapper = FileWrapper(file.file.file)
    content_type = 'application/octet-stream'
    if file.suffix:
        content_type = 'application/{}'.format(file.suffix)
    response = FileResponse(wrapper, content_type=content_type)
    response['Content-Disposition'] = "attachment; filename*=utf-8''{}".format(
        escape_uri_path(file.filename))
    response['Access-Control-Expose-Headers'] = 'Content-Disposition'
    return
