# 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
