Reference documentation and code samples for the Google Cloud Tasks v2beta3 API class AppEngineRouting.
App Engine Routing.
Defines routing characteristics specific to App Engine - service, version,
and instance.
The host is constructed from the domain name of the app associated with
the queue's project ID (for example <app-id>.appspot.com), and the
[service][google.cloud.tasks.v2beta3.AppEngineRouting.service],
[version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and
[instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance]. Tasks
which were created using the App Engine SDK might have a custom domain
name.
By default, the task is sent to the service which is the default
service when the task is attempted.
For some queues or tasks which were created using the App Engine
Task Queue API, [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is
not parsable into
[service][google.cloud.tasks.v2beta3.AppEngineRouting.service],
[version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and
[instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance]. For
example, some tasks which were created using the App Engine SDK use a
custom domain name; custom domains are not parsed by Cloud Tasks. If
[host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is not parsable,
then [service][google.cloud.tasks.v2beta3.AppEngineRouting.service],
[version][google.cloud.tasks.v2beta3.AppEngineRouting.version], and
[instance][google.cloud.tasks.v2beta3.AppEngineRouting.instance] are the
empty string.
By default, the task is sent to the version which is the default
version when the task is attempted.
For some queues or tasks which were created using the App Engine
Task Queue API, [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] is
not parsable into
