AppEngineHttpRequest(mapping=None, *, ignore_unknown_fields=False, **kwargs)
App Engine HTTP request.
The message defines the HTTP request that is sent to an App Engine app when the task is dispatched.
Google IAM permission for the project and the following scope:
The task will be delivered to the App Engine app which belongs to
the same project as the queue. For more information, see
and how routing is affected by
Traffic is encrypted during transport and never leaves Google
datacenters. Because this traffic is carried over a communication
mechanism internal to Google, you cannot explicitly set the protocol
(for example, HTTP or HTTPS). The request to the handler, however,
will appear to have used the HTTP protocol.
The AppEngineRouting used to construct the URL that the task is delivered to can be set at the queue-level or task-level:
- If [app_engine_routing_override is set on the queue][Queue.app_engine_routing_override], this value is used for all tasks in the queue, no matter what the setting is for the [task-level app_engine_routing][AppEngineHttpRequest.app_engine_routing].
url that the task will be sent to is:
Tasks can be dispatched to secure app handlers, unsecure app
handlers, and URIs restricted with
login: admin`` <https://cloud.google.com/appengine/docs/standard/python/config/appref>`__.
Because tasks are not run as any user, they cannot be dispatched to
URIs restricted withlogin: required
Task dispatches also do not follow redirects.
The task attempt has succeeded if the app's request handler returns
an HTTP response code in the range [
299]. The task
attempt has failed if the app's handler returns a non-2xx response
code or Cloud Tasks does not receive response before the
tasks will be retried according to the [retry
(Service Unavailable) is considered an App Engine system error
instead of an application error and will cause Cloud Tasks' traffic
congestion control to temporarily throttle the queue's dispatches.
Unlike other types of task targets, a
429 (Too Many Requests)
response from an app handler does not cause traffic congestion
control to throttle the queue.
The HTTP method to use for the request. The default is POST. The app's request handler for the task's target URL must be able to handle HTTP requests with this http_method, otherwise the task attempt will fail with error code 405 (Method Not Allowed). See `Writing a push task request handler
Task-level setting for App Engine routing. - If [app_engine_routing_override is set on the queue][Queue.app_engine_routing_override], this value is used for all tasks in the queue, no matter what the setting is for the [task-level app_engine_routing][AppEngineHttpRequest.app_engine_routing].
The relative URI. The relative URI must begin with "/" and must be a valid HTTP relative URI. It can contain a path and query string arguments. If the relative URI is empty, then the root path "/" will be used. No spaces are allowed, and the maximum length allowed is 2083 characters.
HTTP request headers. This map contains the header field names and values. Headers can be set when the [task is created][google.cloud.tasks.v2.CloudTasks.CreateTask]. Repeated headers are not supported but a header value can contain commas. Cloud Tasks sets some headers to default values: -
HTTP request body. A request body is allowed only if the HTTP method is POST or PUT. It is an error to set a body on a task with an incompatible HttpMethod.
