Python urllib2: 从 url 接收 JSON 响应

我正在尝试使用 Python 获取一个 URL，响应是 JSON

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

Html 是 str 类型的，我希望是 JSON。有没有什么方法可以将响应捕获为 JSON 或 Python 字典而不是 str。

Be careful about the validation and etc, but the straight solution is this:

import json
the_dict = json.load(response)

If the URL is returning valid JSON-encoded data, use the json library to decode that:

import urllib2
import json


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

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, for Python 3.4
HTTPMessage, returned by r.info()

resource_url = 'http://localhost:8080/service/'
response = json.loads(urllib2.urlopen(resource_url).read())

None of the provided examples on here worked for me. They were either for Python 2 (uurllib2) or those for Python 3 return the error "ImportError: No module named request". I google the error message and it apparently requires me to install a the module - which is obviously unacceptable for such a simple task.

This code worked for me: 

import json,urllib
data = urllib.urlopen("https://api.github.com/users?since=0").read()
d = json.loads(data)
print (d)

Though I guess it has already answered I would like to add my little bit in this

import json
import urllib2
class Website(object):
def __init__(self,name):
self.name = name
def dump(self):
self.data= urllib2.urlopen(self.name)
return self.data


def convJSON(self):
data=  json.load(self.dump())
print data


domain = Website("https://example.com")
domain.convJSON()

Note : object passed to json.load() should support .read() , therefore urllib2.urlopen(self.name).read() would not work . Doamin passed should be provided with protocol in this case http

Python 3 standard library one-liner:

load(urlopen(url))


# imports (place these above the code before running it)
from json import load
from urllib.request import urlopen
url = 'https://jsonplaceholder.typicode.com/todos/1'

you can also get json by using requests as below:

import requests


r = requests.get('http://yoursite.com/your-json-pfile.json')
json_response = r.json()

This is another simpler solution to your question

pd.read_json(data)

where data is the str output from the following code

response = urlopen("https://data.nasa.gov/resource/y77d-th95.json")
json_data = response.read().decode('utf-8', 'replace')
