如何在django中上传word或pdf文件

MEDIA_ROOT = '/path/to/upload/folder/'

from django import forms

class UploadFileForm(forms.Form):
    file = forms.FileField()

from .forms import UploadFileForm
import os

def upload_file(request):
    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            file = form.cleaned_data['file']
            file_path = os.path.join(settings.MEDIA_ROOT, file.name)
            with open(file_path, 'wb') as destination:
                for chunk in file.chunks():
                    destination.write(chunk)
            return HttpResponse('文件上传成功！')
    else:
        form = UploadFileForm()
    return render(request, 'upload.html', {'form': form})

<form method="post" enctype="multipart/form-data">
  {% csrf_token %}
  {{ form }}
  <button type="submit">上传</button>
</form>
