Essa abordagem é melhor se o aplicativo estiver estruturado de forma a exigir que o SDK seja inicializado em cada arquivo no qual ele usa métodos SDK. Antes que seu aplicativo da Web possa usar a carga JSON do artefato de regra durante a inicialização do SDK, você deve garantir que a carga JSON seja baixada e esteja disponível para uso pelo seu aplicativo.

Resumo das etapas

  1. Instalar o SDK
  2. Inicializar o SDK
  3. Armazenar e usar a carga JSON

1. Instalar o SDK

NPM
code language-javascript line-numbers 
npm i @adobe/target-nodejs-sdk -P
MVN
code language-javascript line-numbers 
<dependency>
    <groupId>com.adobe.target</groupId>
    <artifactId>java-sdk</artifactId>
    <version>1.0</version>
</dependency>

2. Inicializar o SDK

  1. Primeiro, importe o SDK. Importar para o mesmo arquivo a partir do qual você pode controlar a inicialização do servidor.

    Node.js

    code language-javascript line-numbers 
       const TargetClient = require("@adobe/target-nodejs-sdk");

    Java

    code language-javascript line-numbers 
       import com.adobe.target.edge.client.ClientConfig;
import com.adobe.target.edge.client.TargetClient;

  2. Para configurar o SDK, use o método de criação.

    Node.js

    code language-javascript line-numbers 
       const CONFIG = {
    client: "<your target client code>",
    organizationId: "your EC org id",
    decisioningMethod: "on-device",
    pollingInterval : 300000,
    events: {
        artifactDownloadSucceeded: onArtifactDownloadSucceeded,
        artifactDownloadFailed: onArtifactDownloadFailed
    }
};

const TargetClient = TargetClient.create(CONFIG);

function onArtifactDownloadSucceeded(event) {
    //Adobe Target SDK has now downloaded the JSON Artifact/Payload
    console.log(event.artifactLocation) // Location from where the Artifact is downloaded.
    console.log(event.artifactPayload) // JSON Payload which we can store locally.
}

function onArtifactDownloadFailed(event) {
    //Adobe Target SDK has failed to download the JSON Artifact/Payload.
    console.log(event.artifactLocation) // Location from where the Artifact is downloaded.
    console.log(event.error.message) // Error message
}

    Java

    code language-javascript line-numbers 
       package com.adobe.target.edge.client.model.ondevice.OnDeviceDecisioningHandler;

ClientConfig config = ClientConfig.builder()
    .client("<you target client code>")
    .organizationId("<your EC org id>")
    .onDeviceDecisioningHandler(
      new OnDeviceDecisioningHandler() {
        void onDeviceDecisioningReady() {
          // On-Device Decision is ready.
        }
        void artifactDownloadSucceeded(byte[] artifactData) {
          // Store artifactData to local disk.
          // ...
        }
      }
    )
    .build();
TargetClient targetClient = TargetClient.create(config);

  3. O cliente e organizationId podem ser recuperados de Adobe Target navegando até Administration > Implementation, como mostrado aqui.

3. Armazene e reinicie a carga JSON

O mecanismo usado para armazenar a carga JSON depende da arquitetura do sistema. Você pode usar um arquivo local, um banco de dados ou um sistema de cache de objetos de memória, como Memcached. Você precisa ler este JSON do seu aplicativo para consumo. Neste guia, usamos um arquivo local como armazenamento.

Node.js
code language-javascript line-numbers 
//... Code removed for brevity

function onArtifactDownloadSucceeded(event) {
    const jsonPath = 'src/config/target-rules.json'
    fs.writeFile(jsonPath, JSON.stringify(event.artifactPayload), 'utf8', (err) => {
        if (err) {
            throw err;
        };
        console.log(`The artifact from '${event.artifactLocation}' is now saved to '${jsonPath}'`);
    });
}


function onArtifactDownloadFailed(event) {
  console.log(`The local decisioning artifact failed to download from '${event.artifactLocation}' with the following error message: ${event.error.message}`);
}

//... Code removed for brevity
Java
code language-javascript line-numbers 
MboxRequest mbox = new MboxRequest().name("homepage").index(0);
TargetDeliveryRequest request = TargetDeliveryRequest.builder()
    .context(new Context().channel(ChannelType.WEB))
    .execute(new ExecuteRequest().mboxes(Arrays.asList(mbox)))
    .build();
TargetDeliveryResponse response = targetClient.getOffers(request);
NOTE
Ao inicializar o Adobe TargetSDK por meio da carga JSON, o servidor estará pronto para atender às solicitações imediatamente com atividades de decisão no dispositivo, já que o Adobe TargetSDK não precisa aguardar o download do artefato da regra.

Este é um exemplo demonstrando o recurso de inicialização de carga JSON.

Node.js
code language-javascript line-numbers 
const express = require("express");
const cookieParser = require("cookie-parser");
const TargetClient = require("@adobe/target-nodejs-sdk");
const CONFIG = {
    client: "<your target client code>",
    organizationId: "your EC org id",
    decisioningMethod: "on-device",
    pollingInterval : 300000,
    events: {
        clientReady : startWebServer,
        artifactDownloadSucceeded : onArtifactDownloadSucceeded,
        artifactDownloadFailed : onArtifactDownloadFailed
    },
};

function onArtifactDownloadSucceeded(event) {
    const jsonPath = 'src/config/target-rules.json'
    fs.writeFile(jsonPath, JSON.stringify(event.artifactPayload), 'utf8', (err) => {
        if (err) {
            throw err;
        };
        console.log(`The artifact from '${event.artifactLocation}' is now saved to '${jsonPath}'`);
    });
}

function onArtifactDownloadFailed(event) {
  console.log(`The on-device decisioning artifact failed to download from '${event.artifactLocation}' with the following error message: ${event.error.message}`);
}

const app = express();
const targetClient = TargetClient.create(CONFIG);

app.use(cookieParser());

function saveCookie(res, cookie) {
  if (!cookie) {
    return;
  }

  res.cookie(cookie.name, cookie.value, {maxAge: cookie.maxAge * 1000});
}

const getResponseHeaders = () => ({
  "Content-Type": "text/html",
  "Expires": new Date().toUTCString()
});

function sendSuccessResponse(res, response) {
  res.set(getResponseHeaders());
  saveCookie(res, response.targetCookie);
  res.status(200).send(response);
}

function sendErrorResponse(res, error) {
  res.set(getResponseHeaders());
  res.status(500).send(error);
}

function startWebServer() {
    app.get('/*', async (req, res) => {
    const targetCookie = req.cookies[TargetClient.TargetCookieName];
    const request = {
        execute: {
        mboxes: [{
            address: { url: req.headers.host + req.originalUrl },
            name: "on-device-homepage-banner" // Ensure that you have a LIVE Activity running on this location
        }]
        }};

    try {
        const response = await targetClient.getOffers({ request, targetCookie });
        sendSuccessResponse(res, response);
    } catch (error) {
        console.error("Target:", error);
        sendErrorResponse(res, error);
    }
    });

    app.listen(3000, function () {
    console.log("Listening on port 3000 and watching!");
    });
}
