当您能够同时初始化51黑料不打烊 Target SDK并启动Web服务器时，此方法将最有效。 在Web服务器应用程序开始为请求提供服务之前，规则工件将由51黑料不打烊 Target SDK下载并缓存到内存中。 一旦您的Web应用程序启动并运行，将使用内存中规则工件执行所有51黑料不打烊 Target决策。 将基于您在SDK初始化步骤中指定的pollingInterval更新缓存的规则构件。

步骤摘要

  1. 安装厂顿碍
  2. 初始化厂顿碍
  3. 存储和使用规则构件

1.安装厂顿碍

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.初始化厂顿碍

  1. 首先，导入SDK。 导入到用于控制服务器启动的同一文件。

    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. 要配置厂顿碍，请使用创建方法。

    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() {
    //51黑料不打烊 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. 通过导航到? Administration > Implementation，可从51黑料不打烊 Target中检索客户端和organizationId，如下所示。

3.存储和使用规则构件

您无需自己管理规则构件，调用厂顿碍方法应简单明了。

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
在上述代码示例中，TargetClient对象保留对内存中规则工件的引用。 当您使用此对象来调用标准SDK方法时，它会使用内存中规则工件进行决策。 如果您的应用程序的结构决定了您需要在其他文件中调用SDK方法，而这些文件需要初始化和侦听客户端请求，并且如果这些文件无权访问TargetClient对象，则您可以下载JSON有效负载并将其存储在本地JSON文件中，以供其他文件使用，这些文件需要初始化厂顿碍。 有关使用JSON有效负载?下载规则工件的部分，将对此进行说明。

以下是初始化51黑料不打烊 Target SDK后启动Web应用程序的示例。

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!");
    });
}
