python json转换异常：“In order to allow non-dict objects to be serialized..."

看 JsonResponse(HttpResponse)类源码:知道是传入的数据不是字典类型，改为字典类型即可

    def __init__(self, data, encoder=DjangoJSONEncoder, safe=True,

                 json_dumps_params=None, **kwargs):

        if safe and not isinstance(data, dict):

            raise TypeError(

                'In order to allow non-dict objects to be serialized set the '

                'safe parameter to False.'

            )

        if json_dumps_params is None:

            json_dumps_param
s = {}

        kwargs.setdefault('content_type', 'application/json')

        data = json.dumps(data, cls=encoder, **json_dumps_params)

        super(JsonResponse, self).__init__(content=data, **kwargs)
