这是什么数据

Question

我正在使用Django，我得到了一个存储在BinaryField中的pdf文件，并试图将其作为数据类型在响应中发送(最好是，我希望根据客户端的请求，尽可能多地发送数据类型(。

class CVPdf(generics.UpdateAPIView):
permission_classes = [IsAuthenticated]
parser_classes = [FileUploadParser]
def get(self, *args):
"""
* ``:param request:`` GET request sent with ``Authorization: Bearer token_id``.
* ``:return:`` Authenticated Seeker CV file
"""
pdf_file= CV.objects.get(id=1).pdf_file
return HttpResponse(pdf_file)

使用python请求库执行GET请求时，我得到了以下数据：

这是什么数据类型？

Answer 1

在我的一个项目中，我为课堂分数制作了一个文件服务功能：

因此，为文件提供服务的代码部分是：

with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type="application/default")
response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)
return response

你要做的是把PDFfilepath放在变量"file_path"中，它会起作用(我想(
