當您能夠初始化 Adobe Target SDK可在您初始化並啟動網頁伺服器的同時啟動。 規則成品將由 Adobe Target SDK並快取至記憶體中，然後網站伺服器應用程式才會開始處理請求。 一旦您的網頁應用程式啟動並執行，所有 Adobe Target 將使用記憶體中的規則成品來執行決定。 快取的規則成品將會根據 pollingInterval 您可以在SDK初始化步驟中指定。

步驟摘要

  1. 安裝SDK
  2. 初始化SDK
  3. 儲存和使用規則成品

1.安裝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.初始化SDK

  1. 首先，匯入SDK。 匯入至您可從其中控制伺服器啟動的相同檔案。

    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. 若要設定SDK，請使用create方法。

    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: {
        clientReady: startWebServer
    }
};

const TargetClient = TargetClient.create(CONFIG);

function startWebServer() {
    //Adobe Target SDK has now downloaded the JSON Artifacts and is available in the memory.
    //You can start your web server now to serve requests now.
}

    Java

    code language-javascript line-numbers 
       ClientConfig config = ClientConfig.builder()
    .client("<you target client code>")
    .organizationId("<your EC org id>")
    .build();
TargetClient targetClient = TargetClient.create(config);

  3. 使用者端和organizationId都可從下列位置擷取： Adobe Target 瀏覽至 管理 > 實施，如下所示。

    <! — 插入image-client-code.png —>
    Target中「管理」下的「實作」頁面

3.儲存和使用規則成品

您不需要自己管理規則成品，呼叫SDK方法應該要簡單明瞭。

Node.js
code language-javascript line-numbers 
//req is the request object from the server request listener method
const targetCookie = req.cookies[TargetClient.TargetCookieName];
const request = {
    context: {
        channel: "web"
    },
    execute: {
        mboxes: [{
            address: { url: req.headers.host + req.originalUrl },
            name: "on-device-homepage-banner"
        }],
    },
};

TargetClient.getOffers({
    request,
    targetCookie
}).then(function(response) {
    //This Target response is coming from the In-memory Target artifact.
    console.log("Target response", response);
}).catch(function(err) {
    console.error("Target:", err);
})
Java
code language-java 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
在上述程式碼範例中， TargetClient 物件包含記憶體內部規則成品的參考。 當您使用此物件來叫用標準SDK方法時，它會使用記憶體中的規則成品來決策。 如果您的應用程式結構化，以致於您必須在初始化並接聽使用者端請求的檔案以外的檔案中呼叫SDK方法，而且如果這些檔案無法存取TargetClient物件，則您可以下載JSON裝載並將其儲存在本機JSON檔案中，以便在其他需要初始化SDK的檔案上使用。 這將在下一節中關於以下內容進行說明 使用JSON裝載下載規則成品.

以下是初始化 Adobe Target SDK.

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
    }
};

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!");
    });
}
