# Google Cloud Tasks Samples | ||
|
||
[![Open in Cloud Shell][shell_img]][shell_link] | ||

|
||
Sample command-line programs for interacting with the Cloud Tasks API | ||
. | ||
|
||
App Engine queues push tasks to an App Engine HTTP target. This directory | ||
contains both the App Engine app to deploy, as well as the snippets to run | ||
locally to push tasks to it, which could also be called on App Engine. | ||
|
||
`create_app_engine_queue_task.py` is a simple command-line program to create | ||
tasks to be pushed to the App Engine app. | ||
|
||
`main.py` is the main App Engine app. This app serves as an endpoint to receive | ||
App Engine task attempts. | ||
|
||
`app.yaml` configures the App Engine app. | ||
|
||
|
||
## Prerequisites to run locally: | ||
|
||
Please refer to [Setting Up a Python Development Environment](https://cloud.google.com/python/setup). | ||
|
||
## Authentication | ||
|
||
To set up authentication, please refer to our | ||
[authentication getting started guide](https://cloud.google.com/docs/authentication/getting-started). | ||
|
||
## Creating a queue | ||
|
||
To create a queue using the Cloud SDK, use the following gcloud command: | ||
|
||
``` | ||
gcloud beta tasks queues create-app-engine-queue my-appengine-queue | ||
``` | ||
|
||
Note: A newly created queue will route to the default App Engine service and | ||
version unless configured to do otherwise. | ||
|
||
## Deploying the App Engine App | ||
|
||
Deploy the App Engine app with gcloud: | ||
|
||
* To deploy to the Standard environment: | ||
``` | ||
gcloud app deploy app.yaml | ||
``` | ||
* To deploy to the Flexible environment: | ||
``` | ||
gcloud app deploy app.flexible.yaml | ||
``` | ||
|
||
Verify the index page is serving: | ||
|
||
``` | ||
gcloud app browse | ||
``` | ||
|
||
The App Engine app serves as a target for the push requests. It has an | ||
endpoint `/example_task_handler` that reads the payload (i.e., the request body) | ||
of the HTTP POST request and logs it. The log output can be viewed with: | ||
|
||
``` | ||
gcloud app logs read | ||
``` | ||
|
||
## 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 beta tasks queues list`. | ||
|
||
``` | ||
export QUEUE_ID=my-appengine-queue | ||
``` | ||
|
||
And finally the location ID, which can be discovered with | ||
`gcloud beta tasks queues describe $QUEUE_ID`, with the location embedded in | ||
the "name" value (for instance, if the name is | ||
"projects/my-project/locations/us-central1/queues/my-appengine-queue", then the | ||
location is "us-central1"). | ||
|
||
``` | ||
export LOCATION_ID=us-central1 | ||
``` | ||
|
||
### Using HTTP Push Queues | ||
|
||
Set an environment variable for the endpoint to your task handler. This is an | ||
example url to send requests to the App Engine task handler: | ||
``` | ||
export URL=https://<project_id>.appspot.com/example_task_handler | ||
``` | ||
|
||
Running the sample will create a task and send the task to the specific URL | ||
endpoint, with a payload specified: | ||
|
||
``` | ||
python create_http_task.py --project=$PROJECT_ID --queue=$QUEUE_ID --location=$LOCATION_ID --url=$URL --payload=hello | ||
``` |
