This library is a reimplementation and subset of json_stream. It enables reading JSON data from a stream rather that loading it all into memory at once. The interface works like lists and dictionaries that are usually returned from
json.load() but require in-order access. Out of order accesses will lead to missing keys and list entries.
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.
Installing from PyPI¶
This library is on PyPI for editors that use it for CircuitPython. In CPython, it is recommended to use json_stream itself.
Installing to a Connected CircuitPython Device with Circup¶
Make sure that you have
circup installed in your Python environment.
Install it with the following command if necessary:
pip3 install circup
circup installed and your CircuitPython device connected use the
following command to install:
circup install adafruit_json_stream
Or the following command to update an existing version:
import ssl import time import adafruit_requests import socketpool import wifi import adafruit_json_stream as json_stream pool = socketpool.SocketPool(wifi.radio) session = adafruit_requests.Session(pool, ssl.create_default_context()) SCORE_URL = "http://site.api.espn.com/apis/site/v2/sports/baseball/mlb/scoreboard" while True: resp = session.get(SCORE_URL) json_data = json_stream.load(resp.iter_content(32)) for event in json_data["events"]: if "Seattle" not in event["name"]: continue for competition in event["competitions"]: for competitor in competition["competitors"]: print(competitor["team"]["displayName"], competitor["score"]) resp.close() time.sleep(60)
