To request JSON from a URL using Python, you need to send an HTTP GET request to the server and provide the Accept: application/json request header with your request. The Accept header tells the server that our Python client is expecting JSON.
Parse JSON - Convert from JSON to Python If you have a JSON string, you can parse it by using the json. loads() method. The result will be a Python dictionary.
To post a JSON to the server using Python Requests Library, call the requests. post() method and pass the target URL as the first parameter and the JSON data with the json= parameter. The json= parameter takes a dictionary and automatically converts it to a JSON string.
I recommend using the awesome requests library:
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 Response Content: https://requests.readthedocs.io/en/master/user/quickstart/#json-response-content
The requests Python module takes care of both retrieving JSON data and decoding it, due to its builtin JSON decoder. Here is an example taken from the module's documentation:
>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...
So there is no use of having to use some separate module for decoding JSON.
requests has built-in .json() method
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))
