如何获取在django的filefield中上传的文件的原始名称

# 导入必要的模块
from django.shortcuts import render
from django.http import HttpResponse

# 定义视图函数
def upload_file(request):
    if request.method == 'POST':
        # 获取包含上传文件的表单数据
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            # 获取上传文件的File对象
            uploaded_file = form.cleaned_data['file_field']
            # 获取上传文件的原始名称
            original_filename = uploaded_file.name
            # 进行其他操作，如保存文件等
            # ...
            return HttpResponse(f"上传成功，文件名：{original_filename}")
    else:
        form = UploadFileForm()
    return render(request, 'upload.html', {'form': form})
