所以我最近迁移到了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，但是在迁移之后，我开始发现这个错误：
typeerror：“bytes”类型的对象不是json可序列化的
在打印了传递给JsonResponse的数据类型之后，我意识到python 3.6将其从dict改为byte。
所以我修改了代码以确保我传递的是一个dict。
在尝试了所有这些之后，我仍然会遇到同样的错误：
data = dict([('status', 0)])
print(data)
print(type(data))
# print(type(json.dumps(data)))
# data = {"status": '0'}
# data = json.dumps(data)
# json.dumps(data.decode("utf-8"))
#response = json.JSONEncoder().encode({"status": 0})
#JsonResponse(data, safe=False)
# response = json.dumps(data)
print(JsonResponse(data, safe=False))
return JsonResponse(data, safe=False)
印刷品：
{'status': 0}
<class 'dict'>
<JsonResponse status_code=200, "application/json">
使用json.dumps选项，可以改为获取此错误
attributeerror:“str”对象没有“get”属性
任何帮助都将不胜感激

最佳答案
问题不在于return JsonResponse({'status': '1'})。
回溯显示当Django试图保存Django会话时发生错误。
你一定是在做这样的事情：
request.session['my_key'] = b'bytes'
对于该示例，您必须解码bytes对象（或使用字符串代替）：
request.session['my_key'] = b'bytes'.decode('utf-8')
