Python urllib2:从url接收JSON响应

Question

我试图使用Python获取URL,响应是JSON.但是,当我跑

import urllib2
response = urllib2.urlopen('https://api.instagram.com/v1/tags/pizza/media/XXXXXX')
html=response.read()
print html

html是str类型,我期待一个JSON.有没有什么办法可以将响应捕获为JSON或python字典而不是str.

Answer 1

如果URL返回有效的JSON编码数据,请使用该json库解码:

import urllib2
import json

response = urllib2.urlopen('https://api.instagram.com/v1/tags/pizza/media/XXXXXX')
data = json.load(response)   
print data

Answer 2

import json
import urllib

url = 'http://example.com/file.json'
r = urllib.request.urlopen(url)
data = json.loads(r.read().decode(r.info().get_param('charset') or 'utf-8'))
print(data)

urllib,用于Python 3.4
HTTPMessage,由r.info()返回
