Tastypie登录返回HttpResonse 500

Question

我正在尝试使用Tastypie登录系统，但是当我发送带有用户数据的json请求时，服务器会响应Http 500.我查看了所有代码并试图调试问题但是我尝试的都没有工作。

我环顾四周，找不到任何可以帮助我的事。

有没有人知道如何解决这个问题，或者我应该做些什么我不是。

感谢。

试试这个，它对我有用！

在终端

In [2]: import requests

In [3]: import json

In [4]: data = {"username" : "test", "password" : "password"}

In [5]: headers = {"content-type": "application/json"}

In [6]: url= "http://localhost:8000/api/v1/user/login/"

In [7]: response = requests.post(url, data=json.dumps(data), headers=headers)

In [8]: response
Out[8]: <Response [200]>

问题是request.raw_post_data已被弃用，应更改为request.body希望这有助于其他任何人遇到问题。
