Django Rest Framework文件上传

Question

我正在使用Django Rest Framework和AngularJs上传文件。我的视图文件如下所示：

class ProductList(APIView):
    authentication_classes = (authentication.TokenAuthentication,)
    def get(self,request):
        if request.user.is_authenticated(): 
            userCompanyId = request.user.get_profile().companyId
            products = Product.objects.filter(company = userCompanyId)
            serializer = ProductSerializer(products,many=True)
            return Response(serializer.data)

    def post(self,request):
        serializer = ProductSerializer(data=request.DATA, files=request.FILES)
        if serializer.is_valid():
            serializer.save()
            return Response(data=request.DATA)

由于post方法的最后一行应返回所有数据，因此我有几个问题：

• 如何检查里面是否有东西request.FILES？
• 如何序列化文件字段？
• 我应该如何使用解析器？

使用FileUploadParser，一切都在请求中。改用put方法，您会在docs中找到一个示例：)

class FileUploadView(views.APIView):
    parser_classes = (FileUploadParser,)

    def put(self, request, filename, format=None):
        file_obj = request.FILES['file']
        # do some stuff with uploaded file
        return Response(status=204)
