AEM Aprenda a generar una imagen con OpenAI o DALL.E 2 y cárguela a DAM para que la velocidad de contenido sea mayor que la de los demás.
AEM Este ejemplo de extensión de la consola de fragmentos de contenido es un barra de acciones extensión que genera una imagen digital a partir de la entrada de lenguaje natural mediante API de OpenAI o DALL.E 2. AEM La imagen generada se cargará en el DAM y la propiedad de imagen del fragmento de contenido seleccionado se actualizará para hacer referencia a esta imagen cargada y recién generada de DAM.
En este ejemplo aprenderá lo siguiente:
El flujo funcional de la extensión de ejemplo es el siguiente:
Generate Image
botón en el barra de acciones abre el modal.Image Description
AEM texto, el fragmento de contenido seleccionado y el host de la acción personalizada de Adobe I/O Runtime.Image Description
texto para especificar qué imagen se debe generar.Este vídeo revisa la generación de imágenes de ejemplo utilizando la extensión OpenAI o DALL.E 2, cómo funciona y cómo se desarrolla. El vídeo tiene marcas de capítulo como Demostración funcional, configuración y código técnico para ver la pieza relevante rápidamente.
El ejemplo utiliza un proyecto de consola de Adobe Developer existente y las siguientes opciones al inicializar la aplicación App Builder mediante aio app init
.

En las secciones siguientes, se muestra información sobre los archivos JavaScript clave de acción de React y Adobe I/O Runtime. Para su referencia, los archivos de claves de web-src
y actions
del proyecto AppBuilder, consulte la sección adobe-appbuilder-cfc-ext-image-generation-code.zip.
El src/aem-cf-console-admin-1/web-src/src/components/App.js
contiene el React router.
Existen dos conjuntos lógicos de rutas:
La primera ruta asigna solicitudes a index.html
, que invoca el componente React responsable de registro de extensión.
<Route index element={<ExtensionRegistration />} />
El segundo conjunto de rutas asigna direcciones URL a componentes de React que representan el contenido del modal de la extensión. El :selection
param representa una ruta de fragmento de contenido de lista delimitada.
Si la extensión tiene varios botones para invocar acciones discretas, registro de extensión asigna a una ruta definida aquí.
<Route
exact path="content-fragment/:selection/generate-image-modal"
element={<GenerateImageModal />}
/>
ExtensionRegistration.js
, asignado al index.html
AEM route, es el punto de entrada para la extensión de la y define:
actionBar
o headerMenu
)getButton()
funciónonClick()
funciónsrc/aem-cf-console-admin-1/web-src/src/components/ExtensionRegistration.js
function ExtensionRegistration() {
const init = async () => {
const guestConnection = await register({
id: extensionId,
methods: {
// Configure your Action Bar button here
actionBar: {
getButton() {
return {
'id': 'generate-image', // Unique ID for the button
'label': 'Generate Image', // Button label
'icon': 'PublishCheck' // Button icon; get name from: https://spectrum.adobe.com/page/icons/ (Remove spaces, keep uppercase)
}
},
// Click handler for the extension button
onClick(selections) {
// Collect the selected content fragment paths
const selectionIds = selections.map(selection => selection.id);
// Create a URL that maps to the
const modalURL = "/index.html#" + generatePath(
"/content-fragment/:selection/generate-image-modal",
{
// Set the :selection React route parameter to an encoded, delimited list of paths of the selected content fragments
selection: encodeURIComponent(selectionIds.join('|')),
}
);
// Open the route in the extension modal using the constructed URL
guestConnection.host.modal.showUrl({
title: "Generate Image",
url: modalURL
})
}
},
}
})
}
init().catch(console.error)
Cada ruta de la extensión, tal como se define en App.js
, se asigna a un componente de React que se procesa en el modal de la extensión.
En esta aplicación de ejemplo, hay un componente React modal (GenerateImageModal.js
) que tiene cuatro estados:
AEM Es importante señalar que cualquier interacción con los de la extensión debe delegarse a un Acción de Adobe I/O Runtime de AppBuilder, que es un proceso independiente sin servidor que se ejecuta en Adobe I/O Runtime.
El uso de acciones de Adobe I/O Runtime AEM para comunicarse con los usuarios, y es para evitar problemas de conectividad de Intercambio de Recursos de Origen Cruzado (CORS).
Si la variable Generar imagen formulario se envía, un formulario personalizado onSubmitHandler()
invoca la acción de Adobe I/O Runtime AEM AEM, pasando la descripción de la imagen, el host (dominio) actual de la y el token de acceso de la cuenta de usuario de. A continuación, la acción llama al de OpenAI Generación de imágenes API para generar una imagen utilizando la descripción de la imagen enviada. Siguiente con AEM Cargar en el del módulo del nodo DirectBinaryUpload
AEM Clase que carga la imagen generada en el sitio de destino y que finalmente utiliza. AEM API de fragmento de contenido para actualizar los fragmentos de contenido.
Cuando se recibe la respuesta de la acción Adobe I/O Runtime, el modal se actualiza para mostrar los resultados de la operación de generación de imágenes.
