python之如何在 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 checkin 都作为 POST 请求推送到我的服务器，其中包含一个名为 checkin 的参数。我正在尝试获取 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，所以我肯定做错了什么。

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", 
    "photo": "https://foursquare.com/img/blank_boy.png", 
    "gender": "male", 
    "homeCity": "New York, NY", 
    "relationship": "self" 
}, 
"venue": { 
    "id": "4ab7e57cf964a5205f7b20e3", 
    "name": "foursquare HQ", 
    "contact": { 
        "twitter": "foursquare" 
    }, 
    "location": { 
        "address": "East Village", 
        "lat": 40.72809214560253, 
        "lng": -73.99112284183502, 
        "city": "New York", 
        "state": "NY", 
        "postalCode": "10003", 
        "country": "USA" 
    }, 
    "categories": [ 
        { 
            "id": "4bf58dd8d48988d125941735", 
            "name": "Tech Startup", 
            "pluralName": "Tech Startups", 
            "shortName": "Tech Startup", 
            "icon": "https://foursquare.com/img/categories/building/default.png", 
            "parents": [ 
                "Professional & Other Places", 
                "Offices" 
            ], 
            "primary": true 
        } 
    ], 
    "verified": true, 
    "stats": { 
        "checkinsCount": 7313, 
        "usersCount": 565, 
        "tipCount": 128 
    }, 
    "url": "http://foursquare.com" 
} 
}" 

请您参考如下方法:

尝试使用 json.loads(checkin_json) 而不是 json.load(request.POST)。注意额外的“s”。
