我推荐使用令人敬畏的requests库：

import requests

url = 'http://maps.googleapis.com/maps/api/directions/json'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

resp = requests.get(url=url, params=params)
data = resp.json() # Check the JSON Response Content documentation below

JSON响应内容：https://requests.readthedocs.io/en/master/user/quickstart/#json-response-content

由于内置了JSON解码器，requests Python模块负责检索JSON数据和解码数据。下面是一个来自模块文档的示例：

>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...

因此，不必使用某个单独的模块来解码JSON。

requests具有内置的.json()方法

import requests
requests.get(url).json()

import urllib
import json

url = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'
result = json.load(urllib.urlopen(url))

使用requests库，漂亮地打印结果，以便更好地定位要提取的键/值，然后使用嵌套的for循环解析数据，在示例中，我一步一步地提取驾驶方向。

import json, requests, pprint

url = 'http://maps.googleapis.com/maps/api/directions/json?'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

data = requests.get(url=url, params=params)
binary = data.content
output = json.loads(binary)

# test to see if the request was valid
#print output['status']

# output all of the results
#pprint.pprint(output)

# step-by-step directions
for route in output['routes']:
        for leg in route['legs']:
            for step in leg['steps']:
                print step['html_instructions']

仅import requests并从json()方法中使用：

source = requests.get("url").json()
print(source)

或者您可以使用以下命令：

import json,urllib.request
data = urllib.request.urlopen("url").read()
output = json.loads(data)
print (output)

试试这个：

import requests
import json

# Goole Maps API.
link = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'

# Request data from link as 'str'
data = requests.get(link).text

# convert 'str' to Json
data = json.loads(data)

# Now you can access Json 
for i in data['routes'][0]['legs'][0]['steps']:
    lattitude = i['start_location']['lat']
    longitude = i['start_location']['lng']
    print('{}, {}'.format(lattitude, longitude))

对于控制台上的漂亮Json：

json.dumps(response.json(), indent=2)

可以使用带缩进的转储。（请import json）
