如何在Django中将Http Post参数的Json值转换为Python Dict？
我正在使用 Django 接收和处理来自 foursquare 实时 api 的推送通知。每个签入都会作为 POST 请求推送到我的服务器，其中包含名为签入的单个参数。我试图获取 checkin 参数的值并将其转换为 python 字典。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，所以我一定做错了什么。
代码是：
import json
def push(request):
if request.is_secure():
checkin_json = request.POST['checkin']
checkin = json.load(request.POST)
post请求的正文是：
"checkin =
{
"id": "4e6fe1404b90c00032eeac34",
"createdAt": 1315955008,
"type": "checkin",
"timeZone": "America/New_York",
"user": {
"id": "1",
"firstName": "Jimmy",
"lastName": "Foursquare",

I am using Django to receive and process push notifications from the foursquare real-time api. Each checkin is pushed as a POST request to my server containing a single parameter named checkin. I am trying to grab the value of the checkin parameter and convert it to a python dict. However, calling json.loads always results in the following error:
NameError: name 'true' is not defined
I know the json is valid, so I must be doing something wrong.
The code is:
import json
def push(request):
if request.is_secure():
checkin_json = request.POST['checkin']
checkin = json.load(request.POST)
The body of the post request is:
"checkin =
{
"id": "4e6fe1404b90c00032eeac34",
"createdAt": 1315955008,
"type": "checkin",
"timeZone": "America/New_York",
"user": {
"id": "1",
"firstName": "Jimmy",
"lastName": "Foursquare",
"photo": "https://foursquare.com/img/blank_boy.png",
"gender": "male",
"homeCity": "New York, NY",
"relationship": "self"
},
"venue": {
"id": "4ab7e57cf964a5205f7b20e3",

尝试使用
json.loads(checkin_json)而不是json.load(request.POST)。注意额外的“s”。Try
json.loads(checkin_json)instead ofjson.load(request.POST). Notice the extra 's'.将
checkin = json.load(request.POST)更改为checkin = json.loads(checkin_json)change
checkin = json.load(request.POST)tocheckin = json.loads(checkin_json)在 python 上，布尔值是大写的（第一个字母是大写）：True/False。
检查一下。
编辑：
注意这一行：
两个“true”值都是小写的，需要大写
On python, boolean values are Capitalized (first letter is uppercase): True/False.
Check this.
EDIT:
Pay attentiot at this lines:
Both "true" values are lowercase and need to be capitalized
