Python Django Tastypie添加内容长度标题

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)

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

模型资源

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

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

我请求所有玩家使用/api/v1/player/？format=xml，但似乎缺少响应标题：Content Length，这导致我的应用程序出现一些问题。如何将其添加到响应标题中

非常感谢。

您可以通过在自己的资源中覆盖create\u response方法来添加内容长度标题，例如：

class MyResource(ModelResource):
   class Meta:
        queryset=MyModel.objects.all()

   def create_response(self, ...)
      # Here goes regular code that do the method from tastypie
      return response_class(content=serialized, content_type=build_content_type(desired_format), Content-Length=value,  **response_kwargs)

您可以通过在自己的资源中覆盖create_Response方法来添加内容长度标题，例如：

class MyResource(ModelResource):
   class Meta:
        queryset=MyModel.objects.all()

   def create_response(self, ...)
      # Here goes regular code that do the method from tastypie
      return response_class(content=serialized, content_type=build_content_type(desired_format), Content-Length=value,  **response_kwargs)

缺少内容长度是由于缺少中间件。

但是您可以像这样手动添加内容长度：

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
