lv_micropython/examples/network/https_client.py

# Very simple HTTPS client example:
# - Connects to a server.
# - Upgrades the connection to a TLS connection.
# - Sends a HTTP request.
# - Reads the result.
#
# This example works in both MicroPython and CPython.
#
# To implement an HTTPS client using less code, use mip to install the requests package:
# https://github.com/micropython/micropython-lib/tree/master/python-ecosys/requests
