Publica un mensaje en el tema
En la consola de Google Cloud , ve a la página Temas de Pub/Sub.
Deberías ver el mensaje que acabas de publicar. El mensaje tiene los datos, Hello World, y la hora en que se publicó.
Cuando se usa la consola de Google Cloud , una extracción individual de un volumen de mensajes bajo a menudo puede mostrar cero mensajes. Si no ves mensajes, haz clic en Extraer varias veces para emitir varias solicitudes de extracción. Esto no es un problema con las bibliotecas cliente de Pub/Sub.

In the Google Cloud console, go to the **Pub/Sub subscriptions** page.\n\n [Go to Subscriptions](https://console.cloud.google.com/cloudpubsub/subscription/list)\n2.

In the Google Cloud console, go to the **Pub/Sub topics**\n page.\n\n [Go to Topics](https://console.cloud.google.com/cloudpubsub/topicList)\n2. Click the `MyTopic` topic.\n\n3.

In the **Messages** tab, click **Pull**.\n\nYou should see the message that you just published. The message has\nthe data, `Hello World`, and the time when the message was\npublished.\n\nWhen using the Google Cloud console, an individual pull for a low\nmessage volume can often return zero messages. If you do not see messages, click\n**Pull** multiple times to issue multiple pull requests. This is not an issue\nwith the [Pub/Sub Client Libraries](/pubsub/docs/publish-receive-messages-client-library).\n\nClean up\n--------\n\n\nTo avoid incurring charges to your Google Cloud account for\nthe resources used on this page, follow these steps.\n\nIf you no longer need the topic and subscription you created, you\ncan delete them.\n\nTo delete the topic and subscription, complete these steps:\n\n1. Go to the\n **Topics**\n page.\n\n2. Check the checkbox next to `MyTopic` and click\n **Delete**.\n\n3. Complete the steps in the confirmation window to permanently delete the\n topic.\n\nOr you can [delete the project](https://console.cloud.google.com/cloud-resource-manager) that you created.\n\nWhat's next\n-----------\n\n- Learn more about the Pub/Sub [concepts](/pubsub/docs/overview)\n discussed in this page.\n\n- Read the [basics of the Pub/Sub service](/pubsub/docs/pubsub-basics).\n\n- Work through an [end-to-end example](/pubsub/docs/building-pubsub-messaging-system)\n of a Pub/Sub system.\n\n- Try another Pub/Sub quickstart that\n uses [client libraries](/pubsub/docs/publish-receive-messages-client-library)\n or the [Google Cloud CLI](/pubsub/docs/publish-receive-messages-gcloud).\n\n- Learn how to create [topics](/pubsub/docs/create-topic)\n and publish [messages](/pubsub/docs/publisher).\n\n- [Choose](/pubsub/docs/subscriber) or [create](/pubsub/docs/create-subscription) a subscription.\n\n- Learn more about [Pub/Sub APIs](/pubsub/docs/reference/service_apis_overview)."]]
