Example 26 with Queue

use of com.google.cloud.tasks.v2.Queue in project nomulus by google.

the class CloudTasksUtils method createTask.

/**
 * Create a {@link Task} to be enqueued.
 *
 * @param path the relative URI (staring with a slash and ending without one).
 * @param method the HTTP method to be used for the request, only GET and POST are supported.
 * @param service the App Engine service to route the request to. Note that with App Engine Task
 *     Queue API if no service is specified, the service which enqueues the task will be used to
 *     process the task. Cloud Tasks API does not support this feature so the service will always
 *     needs to be explicitly specified.
 * @param params a multi-map of URL query parameters. Duplicate keys are saved as is, and it is up
 *     to the server to process the duplicate keys.
 * @return the enqueued task.
 * @see <a
 *     href=ttps://cloud.google.com/appengine/docs/standard/java/taskqueue/push/creating-tasks#target>Specifyinig
