python - Django Tastypie 添加 Content-Length header

Question

我是 Django 开发的新手。我有一个资源和模型:

型号

class Player(models.Model):
    pseudo = models.CharField(max_length=32, unique=True)

模型资源

class PlayerResource(ModelResource):
    class Meta:
        queryset = Player.objects.all()
        resource_name = 'player'
        authentication = BasicAuthentication()
        authorization = Authorization()
        serializer = Serializer(formats=['xml'])
        filtering = {
            'pseudo': ALL,
        }

我正在请求所有播放器/api/v1/player/?format=xml 但似乎缺少响应 header :Content-Length，这会导致我的应用程序出现一些问题。如何将它添加到响应 header 中？

非常感谢。

缺少 Content-Length 是因为缺少中间件。

但是您可以像这样手动添加 Content-Length :

def create_response(self, request, data, response_class=HttpResponse, **response_kwargs):
        desired_format = self.determine_format(request)
        serialized = self.serialize(request, data, desired_format)
        response = response_class(content=serialized, content_type=build_content_type(desired_format), **response_kwargs)
        response['Content-Length'] = len(response.content)
        return response
