在Django中上传和下载xlsx文件

编程问答 2022-06-03

问题描述

我正在尝试使用将文件上传（xlsx）到s3的视图。还有一个芹菜功能，应该下载此文件，以便我可以执行一些操作。

我的观点：

class ImportView(APIView):
    parser_classes = (FileUploadParser,)

    def post(self,request,filename):
        imported = ImportSerializer(data=request.data)
        fs = FileSystemStorage(tempfile.gettempdir())
        file_name = fs.save(content=new_colabs.validated_data["file"],name="import.xlsx")
        full_path = os.path.join(fs.location,file_name)
        object_name = file_name
        s3 = boto3.client("s3")
        s3.upload_file(full_path,"my_bucket",file_name)
        # call celery here...
        return Response(status=status.HTTP_200_OK)

我的芹菜任务

def example_download_funciont(self):
    s3 = boto3.client("s3")
    bucket = s3.Bucket("my_bucket")
    with open(file_name,'wb') as data:
        file = bucket.download_fileobj(object_name,data)
    workbook = load_workbook(file)
    # [...]

运行此代码，我可以将其上传到s3。但是，当我尝试直接通过aws控制台访问它时，出现此错误：

在celery任务中，我无法下载文件。当我打电话给file时，我得到 None。

有人可以指出我的向导吗？我在botocore文档中看到了它，但没有成功。
