Tastypie登录返回HttpResonse 500

Question

我试图让一个Tastypie登录系统工作，但是当我发送一个JSON请求与用户数据时，服务器响应Http 500.我已经查看了我的所有代码并尝试调试的问题，但没有我试着工作。

我环顾四周，找不到任何东西来帮助我。

有谁知道我该如何去解决这个问题，或者如果有什么我应该做的，我不是。

谢谢。

import json 
import requests

headers = {"content-type": "application/json"} 
url = "http://localhost:8000/api/v1/user/login/" 

response = requests.post(url, data=json.dumps(data), headers=headers) 

print response 

Answer 1

问题是与request.raw_post_data它的弃用，应改为request.body希望这可以帮助其他人有问题。
