This sample demonstrates how to use the Cloud Tasks client library.

create_http_task.py is a simple command-line program to create tasks to be pushed to an URL endpoint.

create_http_task_with_token.py is a simple command-line program to create tasks to be pushed to an URL endpoint with authorization header.

Prerequisites to run locally:

Please refer to Setting Up a Python Development Environment.

Authentication

Creating a queue

To create a queue (named my-queue) using the Cloud SDK, use the following gcloud command:

gcloud tasks queues create my-queue

Run the Sample Using the Command Line

Set environment variables:

First, your project ID:

export PROJECT_ID=my-project-id

Then the queue ID, as specified at queue creation time. Queue IDs already created can be listed with gcloud tasks queues list.

export QUEUE_ID=my-queue

And finally the location ID, which can be discovered with gcloud tasks queues describe my-queue, with the location embedded in the "name" value (for instance, if the name is "projects/my-project/locations/us-central1/queues/my-queue", then the location is "us-central1").

export LOCATION_ID=us-central1

Creating Tasks with HTTP Targets

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

export URL=https://example.com/task_handler

Running the sample will create a task and send the task to the specific URL endpoint, with a payload specified:

python create_http_task.py --project=$PROJECT_ID --queue=$QUEUE_ID --location=$LOCATION_ID --url=$URL --payload=hello
