python - 无法访问 Python 中 JSON 响应中的节点/标签

Question

终于开始学习Python了。阅读了关于该主题的所有其他问题后，我扣除了我是个白痴。

我正在向如下所示的开放 API 发出 Python 请求

import requests
import json

url = 'http://api.turfgame.com/v4/users'
payload = [{"name": "tbone"}]
headers = {'content-type': 'application/json'}

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

一切顺利，我可以打印响应

print r.text

但是，当我想访问响应中的某些标签/节点时，我遇到了麻烦。输出是

[{"country":"se","medals":[34,54,13,5,46,28,16,6],"zones":[323,7577,14606],"pointsPerHour":21,"points":21809,"blocktime":17,"taken":2290,"name":"tbone","totalPoints":347388,"rank":30,"id":95195,"place":1931,"uniqueZonesTaken":269,"region":{"name":"Stockholm","id":141}}]

我试过了

rj = r.json()
print rj['name']

但这只会给我

Traceback (most recent call last):
File "post.py", line 16, in <module>
print rj['name']
TypeError: list indices must be integers, not str

我无法理解如何访问 JSON 响应中的任何单个标签/节点。

Answer 1

你得到的答案:[{"country":"se",..."region":{"name":"Stockholm","id":141}}]是 JSON 对象的列表(注意字典周围的 [])。

因此，要获得您的对象，您必须这样做:

rj = r.json()
print rj[0]['name']    # the [0] to indicate you take the first element of your list
