如何从Python中的JSON输出中获取任何项的值?

如何从Python中的JSON输出中获取任何项的值?,python,python-2.7,confluence-rest-api,Python,Python 2.7,Confluence Rest Api,我在python中有一个函数,它以JSON格式获取数据,我需要获取一个项的值并将其存储在变量中,这样我就可以使用另一个函数了 import requests import json import sys def printResponse(r): print '{} {}\n'.format(json.dumps(r.json(), sort_keys=True, indent=4, separators=(',', ': ')), r) r = requests

我在python中有一个函数,它以JSON格式获取数据,我需要获取一个项的值并将其存储在变量中,这样我就可以使用另一个函数了

import requests
import json
import sys
def printResponse(r):
    print '{} {}\n'.format(json.dumps(r.json(),
    sort_keys=True,
    indent=4,
    separators=(',', ': ')), r)
r = requests.get('https://wiki.tourist.com/rest/api/content',
    params={'title' : 'Release Notes for 1.1n1'},
    auth=('ABCDE', '*******'))
printResponse(r)
getPageid = json.loads(r)
value = int(getPageid['results']['id'])
我试图在变量“value”中获取id(160925)项的值,以便将其用于另一个函数

import requests
import json
import sys
def printResponse(r):
    print '{} {}\n'.format(json.dumps(r.json(),
    sort_keys=True,
    indent=4,
    separators=(',', ': ')), r)
r = requests.get('https://wiki.tourist.com/rest/api/content',
    params={'title' : 'Release Notes for 1.1n1'},
    auth=('ABCDE', '*******'))
printResponse(r)
getPageid = json.loads(r)
value = int(getPageid['results']['id'])
下面是JSON输出

JSON响应中的
“results”
键似乎对应于一个列表,因此您需要索引到该列表中以获取dict


例如,
getPageid['results'][0]['id']
应该为
“results”
列表中的第一个对象返回
“id”
键的字符串值

我收到了这个错误,getPageid=json.loads(r)文件“C:\Python27\lib\json\u init.py”,第339行,在loads return\u default\u decoder.decode文件中“C:\Python27\lib\json\decoder.py”,第364行,在decode obj中,end=self.raw_decode(s,idx=_w(s,0.end())TypeError:需要字符串或缓冲区感谢您给了我正确的方向。我现在可以得到ver=int(info['results'][0]['id'])print ver的结果
