urlpatterns = [
  
    path('upload',views.test_upload)

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

主路由：

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

分路由：

urlpatterns = [
  
    path('upload',views.test_upload)
]

models:

class Content(models.Model):
    title = models.CharField('标题', max_length=100)
    picture = models.FileField(upload_to='picture')

views：

def test_upload(request):
    if request.method == 'POST':
        file = request.FILES.get('file')
        title = request.POST.get('title')
        Content.objects.create(title=title,file=file)
        return HttpResponse('上传成功')
    elif request.method == 'GET':
        return render(request,'node/test_upload.html')
