Python3.6 JsonResponse问题

Question

因此，我最近迁移到了Python 3.6和Django 1.11，我的JsonResponse代码如下所示：

   return JsonResponse({'status': '1'}) 

它工作得很好，但在迁移之后，我开始出现以下错误：

TypeError: Object of type 'bytes' is not JSON serializable

在打印了传递给JsonResponse的数据类型之后，我意识到python3.6将其从dict改为byte。 所以我修改了密码，以确保我通过了口述

在尝试了所有这些之后，我仍然会遇到同样的错误：

^{pr2}$

印刷品：

    {'status': 0}
    <class 'dict'>
    <JsonResponse status_code=200, "application/json">

和json.dumps文件选项y会得到这个错误

AttributeError: 'str' object has no attribute 'get'

任何帮助都将不胜感激

问题不是return JsonResponse({'status': '1'})。在

回溯显示当Django尝试保存Django会话时发生错误。在

您必须在视图中执行以下操作：

request.session['my_key'] = b'bytes'

对于该示例，您必须解码bytes对象（或改用字符串）：

^{pr2}$
