Question

我正在使用Django从foursquare实时api接收和处理推送通知。每个签入都作为POST请求推送到包含名为checkin的单个参数的服务器。我试图获取checkin参数的值并将其转换为python dict。但是，调用json.loads总是会导致以下错误：

NameError: name 'true' is not defined

我知道json是有效的，所以我一定做错了。

代码是：

import json    
def push(request):
  if request.is_secure():
    checkin_json = request.POST['checkin']
    checkin = json.load(request.POST)

发布请求的正文是：

"checkin =

"createdAt": 1315955008,

}"

Answer 1

尝试使用json.loads(checkin_json)代替json.load(request.POST)。注意额外的's'。

Answer 2

将checkin = json.load(request.POST)更改为checkin = json.loads(checkin_json)

Answer 3

在python上，布尔值为大写（第一个字母为大写）：True / False。

检查一下。

编辑：请注意以下几点：

"primary": true
    }
],
"verified": true,

两个“true”值都是小写的，需要大写
