我尝试使用 django-rest-framework 上传文件。 这是我尝试过的代码。

        videofile = request.FILES['videoData']
        fs = FileSystemStorage()
        filename = fs.save(videofile.name, videofile)
        user = request.user
        File.objects.create(
            user = user,
            title = request.data['videotitle'],
            url = filename,
            categorys = request.data['categories'],
            preveimage = request.data['vidoePrevimg'],
            filetype = request.data['videoType'],
            filesize = request.data['videoSize']
        )

        status_code = status.HTTP_200_OK
        response = {
            'success': 'true',
            'status code': status_code,
            'message': 'Video uploaded successfully',
        }

它在本地工作正常，当我将它部署到 heroku 时，大多数 API 工作正常，除了文件上传。 服务器返回 503 错误。

这是 heroku 日志。
