Django的REST框架，圖像突破上上傳

Question

我有型號產品：

class Product(models.Model): 
    ... 
    image = models.ImageField(
     upload_to=lambda instance, filename: 'images/{0}/{1}'.format(instance.id, filename), 
     max_length=254, blank=True, null=True 
    ) 
    ... 

然後，我有串行：

class ProductSerializer(serializers.ModelSerializer): 
    class Meta: 
     model = Product 
     fields = (
      ... 
      'image', 
      ... 
     ) 

然後我有意見：

class ProductViewSet(BaseViewSet, viewsets.ModelViewSet): 
    queryset = Product.objects.all() 
    serializer_class = ProductSerializer 
    @detail_route(methods=['POST']) 

    def upload_image(self, request, *args, **kwargs): 
     upload = request.data['file'] 
     print(upload.name) 
     product = self.get_object() 
     product.image.delete() 

     upload = request.data['file'] 
     product.image.save(upload.name, upload) 

     return Response({'Location': product.image.url}, status=status.HTTP_201_CREATED) 

問題是隻有圖像。在瀏覽器黑色窗口中上傳圖像更改的「源代碼」，並且無法打開它。 MP3和PDF格式正常工作。爲什麼會發生？謝謝。

也許問題是與base64圖像？在這種情況下，您應該從drf_base64.serializers中導入ModelSerializer並從中繼承。
