在 django Rest api 中使用 POST 进行 Json 解析错误

Question

我正在尝试通过 Django REST 框架实现一个简单的 GET/POST api

views.py

class cuser(APIView):
def post(self, request):
   stream  = BytesIO(request.DATA)
    json = JSONParser().parse(stream)
    return Response()

urls.py

from django.conf.urls import patterns, url
from app import views
urlpatterns = patterns('',

           url(r'^challenges/',views.getall.as_view() ),
           url(r'^cuser/' , views.cuser.as_view() ),
      )

我正在尝试POST一些json到/api/cuser/(api是我项目的urls.py中的命名空间)，JSON

{
"username" : "abhishek",
"email" : "john@doe.com",
"password" : "secretpass"
}

我尝试从可浏览的API页面和httpie(一个类似于curl的python工具)

httpie 命令

http --json POST http://localhost:58601/api/cuser/ username=abhishek email=john@doe.com password=secretpass

但我收到 JSON 解析错误:

JSON parse error - Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

使用 --verbose --debug 的整个调试消息

    POST /api/cuser/ HTTP/1.1

{"username": "abhishek", "email": "john@doe.com", "password": "aaezaakmi1"}

{"detail":"JSON parse error - Expecting property name enclosed in double quotes: line 1 column 2 (char 1)"}

Answer 1

我通过 Google 到达此帖子

"detail": "JSON parse error - Expecting property name enclosed in double-quotes": Turns out you CANNOT have a trailing comma in JSON.

因此，如果您收到此错误，您可能需要更改如下帖子:

{
    "username" : "abhishek",
    "email" : "john@doe.com",
    "password" : "secretpass",
}

对此:

{
    "username" : "abhishek",
    "email" : "john@doe.com",
    "password" : "secretpass"
}

请注意 JSON 对象中最后一个属性后面删除的逗号。
