Class AppEngineHttpRequest (2.55.0) 

public final class AppEngineHttpRequest extends GeneratedMessageV3 implements AppEngineHttpRequestOrBuilder

App Engine HTTP request.

The message defines the HTTP request that is sent to an App Engine app when the task is dispatched.

This proto can only be used for tasks in a queue which has app_engine_http_target set.

Using AppEngineHttpRequest requires appengine.applications.get Google IAM permission for the project and the following scope:

https://www.googleapis.com/auth/cloud-platform

The task will be delivered to the App Engine app which belongs to the same project as the queue. For more information, see How Requests are Routed and how routing is affected by dispatch files. 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 set, app_engine_routing_override is used for all tasks in the queue, no matter what the setting is for the task-level app_engine_routing.

The url that the task will be sent to is:

  • url = host + relative_url

    Tasks can be dispatched to secure app handlers, unsecure app handlers, and URIs restricted with login: admin. Because tasks are not run as any user, they cannot be dispatched to URIs restricted with login: 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 [200 - 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 deadline. Failed tasks will be retried according to the retry configuration. 503 (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.

Methods

containsHeaders(String key)

public boolean containsHeaders(String key)

HTTP request headers.

This map contains the header field names and values. Headers can be set when the task is created. Repeated headers are not supported but a header value can contain commas.

Cloud Tasks sets some headers to default values:

  • User-Agent: By default, this header is "AppEngine-Google; (+http://code.google.com/appengine)". This header can be modified, but Cloud Tasks will append "AppEngine-Google; (+http://code.google.com/appengine)" to the modified User-Agent.

    If the task has a payload, Cloud Tasks sets the following headers:

  • Content-Type: By default, the Content-Type header is set to "application/octet-stream". The default can be overridden by explicitly setting Content-Type to a particular media type when the task is created. For example, Content-Type can be set to "application/json".

  • Content-Length: This is computed by Cloud Tasks. This value is output only. It cannot be changed.

    The headers below cannot be set or overridden:

  • Host

  • X-Google-*

  • X-AppEngine-*

    In addition, Cloud Tasks sets some headers when the task is dispatched, such as headers containing information about the task; see request headers. These headers are set only when the task is dispatched, so they are not visible when the task is returned in a Cloud Tasks response.

    Although there is no specific limit for the maximum number of headers or the size, there is a limit on the maximum size of the Task. For more information, see the CreateTask documentation.
