Question

最后尝试学习Python。在阅读了有关该主题的所有其他问题后，我已经扣除了我是一个白痴。

我正在向一个开放的API发出Python请求，如下所示

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，我可以打印回复

print r.text

然而，当我想要访问我遇到墙壁的响应中的某些标签/节点时，它就是这样。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}}]

我已经尝试

了

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

但那只给了我

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记/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[]。）

所以，要获得你的对象，你必须这样做：

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

无法在Python中访问JSON响应中的节点/标记
