Saiba como gerar uma imagem usando OpenAI ou DALL.E 2 e carregá-la no DAM do AEM para velocidade de conteúdo.
Este exemplo de extensão do Console de fragmentos de conteúdo do AEM é um barra de ação extensão que gera imagem digital da entrada de linguagem natural usando API OpenAI ou DALL.E 2. A imagem gerada é carregada no DAM AEM e a propriedade de imagem do fragmento de conteúdo selecionado é atualizada para fazer referência a essa imagem recém-gerada e carregada do DAM.
Neste exemplo, você aprenderá:
O fluxo funcional da extensão de exemplo é o seguinte:
Generate Image
botão na caixa barra de ação abre o modal.Image Description
texto, o fragmento de conteúdo selecionado e o host AEM para o ação personalizada do Adobe I/O Runtime.Image Description
texto para especificar qual imagem deve ser gerada.Este exemplo se estende ao ponto de extensão actionBar
para adicionar um botão personalizado ao Console de fragmentos de conteúdo.
IU do AEM estendida | Ponto de extensão |
---|---|
Console de fragmentos de conteúdo | Barra de ação |
O exemplo usa um projeto existente do Adobe Developer Console e as seguintes opções ao inicializar o aplicativo App Builder via aio app init
.

Nas seções a seguir, você aprenderá sobre os principais arquivos JavaScript das ações do React e do Adobe I/O Runtime. Para sua referência, os arquivos principais de web-src
e actions
pasta do projeto AppBuilder forem fornecidas, consulte adobe-appbuilder-cfc-ext-image-generation-code.zip.
A variável src/aem-cf-console-admin-1/web-src/src/components/App.js
contém o Roteador React.
Há dois conjuntos lógicos de rotas:
A primeira rota mapeia solicitações para o index.html
, que invoca o componente do React responsável pela registro de extensão.
<Route index element={<ExtensionRegistration />} />
O segundo conjunto de rotas mapeia URLs para componentes do React que renderizam o conteúdo do modal da extensão. A variável :selection
param representa um caminho de fragmento de conteúdo de lista delimitada.
Se a extensão tiver vários botões para chamar ações distintas, cada um registro de extensão mapeia para uma rota definida aqui.
<Route
exact path="content-fragment/:selection/generate-image-modal"
element={<GenerateImageModal />}
/>
ExtensionRegistration.js
, mapeado para o index.html
é o ponto de entrada para a extensão AEM e define:
actionBar
ou headerMenu
)getButton()
funçãoonClick()
funçãosrc/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 rota da extensão, conforme definido em App.js
, mapeia para um componente React que é renderizado no modal da extensão.
Neste aplicativo de exemplo, há um componente modal do React (GenerateImageModal.js
) que tem quatro estados:
importante, qualquer interação com o AEM a partir da extensão deve ser delegada a um Ação do AppBuilder Adobe I/O Runtime, que é um processo separado e sem servidor em execução Adobe I/O Runtime.
O uso de ações do Adobe I/O Runtime para se comunicar com o AEM é para evitar problemas de conectividade com o CORS (Cross-Origin Resource Sharing, Compartilhamento de recursos entre origens).
Quando a variável Gerar imagem for enviado, um formulário personalizado onSubmitHandler()
invoca a ação Adobe I/O Runtime, transmitindo a descrição da imagem, o host AEM atual (domínio) e o token de acesso AEM do usuário. A ação chama, então, a função de Geração de imagem API para gerar uma imagem usando a descrição da imagem enviada. Próximo uso Upload do AEM do módulo do nó DirectBinaryUpload
a classe it carrega a imagem gerada para o AEM e, finalmente, usa API de fragmento de conteúdo do AEM para atualizar os fragmentos de conteúdo.
Quando a resposta da ação Adobe I/O Runtime é recebida, o modal é atualizado para exibir os resultados da operação de geração de imagem.
