Package com.google.cloud.tasks.v2beta2

Class AppEngineHttpRequest

  • All Implemented Interfaces:
    AppEngineHttpRequestOrBuilder, com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, Serializable
    public final class AppEngineHttpRequest
extends com.google.protobuf.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][google.cloud.tasks.v2beta2.Queue.app_engine_http_target]
 set.

 Using [AppEngineHttpRequest][google.cloud.tasks.v2beta2.AppEngineHttpRequest]
 requires
 [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
 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](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
 and how routing is affected by
 [dispatch
 files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
 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][google.cloud.tasks.v2beta2.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][google.cloud.tasks.v2beta2.AppEngineHttpTarget.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][google.cloud.tasks.v2beta2.AppEngineHttpRequest.app_engine_routing].


 The `url` that the task will be sent to is:

 * `url =` [host][google.cloud.tasks.v2beta2.AppEngineRouting.host] `+`
   [relative_url][google.cloud.tasks.v2beta2.AppEngineHttpRequest.relative_url]

 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 with
 [`login:
 required`](https://cloud.google.com/appengine/docs/standard/python/config/appref)
 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][Task.dispatch_deadline]. Failed
 tasks will be retried according to the
 [retry configuration][google.cloud.tasks.v2beta2.Queue.retry_config]. `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.

      • getHeadersCount

        public int getHeadersCount()
        Description copied from interface: AppEngineHttpRequestOrBuilder
         HTTP request headers.

 This map contains the header field names and values.
 Headers can be set when the
 [task is created][google.cloud.tasks.v2beta2.CloudTasks.CreateTask].
 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][google.cloud.tasks.v2beta2.AppEngineHttpRequest.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][google.cloud.tasks.v2beta2.CloudTasks.CreateTask].
   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](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_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][google.cloud.tasks.v2beta2.Task]. For more information, see the
 [CreateTask][google.cloud.tasks.v2beta2.CloudTasks.CreateTask]
