Sample command-line programs for interacting with the Cloud Tasks API

.

* To deploy to the Standard environment:

```

```

* To deploy to the Flexible environment:

```

```

Running the sample will create a task, targeted at the `/example_task_handler`

Set an environment variable for the endpoint to your task handler. This is an

example url to send requests to the App Engine task handler:

Running the sample will create a task and send the task to the specific URL

endpoint, with a payload specified:

Now view that the payload was received and verify the payload:

runtime: python

env: flex

entrypoint: gunicorn -b :$PORT --threads=4 main:app
