# It is absolutely CRITICAL that you use certificate validation to ensure and guarantee that
# 1. you are indeed sending the message to *.hanatrial.ondemand.com and
# 2. that you avoid the possibility of TLS/SSL MITM attacks which would allow a malicious person to capture the OAuth token
# URLLIB3 DOES NOT VERIFY CERTIFICATES BY DEFAULT
# Therefore, install urllib3 and certifi and specify the PoolManager as below to enforce certificate check
# See https://urllib3.readthedocs.org/en/latest/security.html for more details

# use with or without proxy
http = urllib3.PoolManager(
	cert_reqs='CERT_REQUIRED', # Force certificate check.
	ca_certs=certifi.where(),  # Path to the Certifi bundle.
)
# http = urllib3.proxy_from_url('http://proxy_host:proxy_port')

# interaction for a specific Device instance - replace 'd000-e000-v000-i000-c000-e001' with your specific Device ID

body='{"mode":"async", "messageType":"m0t0y0p0e1", "messages":[{"sensor":"sensor1", "value":"20", "timestamp":1468991773}]}'

# It is also possible to send multiple messages (3 in this example) in a single request that conform to the same message type.
# body='{"mode":"async", "messageType":"m0t0y0p0e1", "messages":[{"sensor":"sensor1", "value":"20", "timestamp":1468991773},{"sensor":"sensor1", "value":"21", "timestamp":1468991873},{"sensor":"sensor1", "value":"22", "timestamp":1468991973}]}'

# Because every message field in a message type definition defines its position (see message type example above) it is also possible to compress the messages array by omitting the field names.
# Please be aware is that value order is very important in this case (it should match to the message type field positions like specified during message type creation)
# body='{"mode":"async","messageType":"m0t0y0p0e1","messages":[["sensor1","20",1468991773],["sensor1","21",1468991873],["sensor1","22",1468991973]]}'
