django - 如何使用 Django Rest Framework 设置 Content-Disposition header

Question

我正在使用 Django REST 框架提供图像。不幸的是它下载而不是显示。我想我必须设置标题 Content-Disposition = 'inline' .我如何在 View 中执行此操作或 Renderer ?

class ImageRenderer(renderers.BaseRenderer):
    media_type = 'image/*'
    format = '*'
    charset = None
    render_style = 'binary'

    def render(self, data, media_type=None, renderer_context=None):
        return data

class ImageView(APIView):
    renderer_classes = (ImageRenderer, )

    def get(self, request, format=None):
        image=MyImage.objects.get(id=1)
        image_file = image.thumbnail_png.file
        return Response(image)

根据 this page在 Django 文档中，您可以设置 Content-Disposition以这种方式 header :

response = Response(my_data, content_type='image/jpeg')
response['Content-Disposition'] = 'attachment; filename="foo.jpeg"'
