python 里面 JsonResponse (book_list,safe=False)

代码为：

 # 查询所有图书 、 增加图书 def get(self,request):      queryset = BookInfo.objects.all()     book_list = []      for book in queryset:         book_list.append({             'id':book.id,             'bread':book.bread          })     return JsonResponse (book_list,safe=False)

遇到问题：

JsonResponse (book_list,safe=False)

safe=False 这是什么鬼 ？

解决方案：

down 下源码后 ：

 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_params = {}     kwargs.setdefault('content_type', 'application/json')     data = json.dumps(data, cls=encoder, **json_dumps_params)     super(JsonResponse, self).__init__(content=data, **kwargs)

最终答案：

'In order to allow non-dict objects to be serialized set the ' 'safe parameter to False.'
