clearHost()

publicAppEngineRouting.BuilderclearHost()

Output only. The host that the task is sent to.

For more information, see How Requests are Routed.

The host is constructed as:

  • host = [application_domain_name]</br> | [service] + '.' + [application_domain_name]</br> | [version] + '.' + [application_domain_name]</br> | [version_dot_service]+ '.' + [application_domain_name]</br> | [instance] + '.' + [application_domain_name]</br> | [instance_dot_service] + '.' + [application_domain_name]</br> | [instance_dot_version] + '.' + [application_domain_name]</br> | [instance_dot_version_dot_service] + '.' + [application_domain_name]

  • application_domain_name = The domain name of the app, for example <app-id>.appspot.com, which is associated with the queue's project ID. Some tasks which were created using the App Engine SDK use a custom domain name.

  • service = service

  • version = version

  • version_dot_service = version + '.' + service

  • instance = instance

  • instance_dot_service = instance + '.' + service

  • instance_dot_version = instance + '.' + version

  • instance_dot_version_dot_service = instance + '.' + version + '.' + service

    If service is empty, then the task will be sent to the service which is the default service when the task is attempted.

    If version is empty, then the task will be sent to the version which is the default version when the task is attempted.

    If instance is empty, then the task will be sent to an instance which is available when the task is attempted.

    If service, version, or instance is invalid, then the task will be sent to the default version of the default service when the task is attempted.

string host = 4;

Returns
Type Description

This builder for chaining.

clearInstance()

publicAppEngineRouting.BuilderclearInstance()

App instance.

By default, the task is sent to an instance which is available when the task is attempted.

Requests can only be sent to a specific instance if manual scaling is used in App Engine Standard. App Engine Flex does not support instances. For more information, see App Engine Standard request routing and App Engine Flex request routing.

If host is not parsable, then service, version, and instance are the empty string.
