Cloud IoT Core Python HTTP example

This sample app publishes data to Cloud Pub/Sub using the HTTP bridge provided as part of Google Cloud IoT Core. For detailed running instructions see the HTTP code samples guide.

Setup

  1. Use virtualenv to create a local Python environment.
virtualenv env && source env/bin/activate
  1. Install the dependencies
pip install -r requirements.txt

Running the Sample

The following snippet summarizes usage:

cloudiot_http_example.py [-h]
    --project_id PROJECT_ID
    --registry_id REGISTRY_ID
    --device_id DEVICE_ID
    --private_key_file PRIVATE_KEY_FILE
    --algorithm {RS256,ES256}
    --message_type={event,state}
    [--cloud_region CLOUD_REGION]
    [--ca_certs CA_CERTS]
    [--num_messages NUM_MESSAGES]

For example, if your project ID is blue-jet-123, the following example shows how you would execute using the configuration from the HTTP code samples guide:

python cloudiot_http_example.py \
    --registry_id=my-registry \
    --project_id=blue-jet-123 \
    --device_id=my-python-device \
    --message_type=event \
    --algorithm=RS256 \
    --private_key_file=../rsa_private.pem
