一般而言，實作專案時，您在AEM和Adobe Campaign中都有自訂程式碼。使用現有API，您可以在Adobe Campaign中從AEM或從AEM呼叫Adobe Campaign的自訂程式碼。本檔案將說明如何執行此操作。

先決條件 prerequisites

您必須安裝下列專案：

Adobe Experience Manager
Adobe Campaign 6.1

如需詳細資訊，請參閱整合AEM與Adobe Campaign 6.1。

範例1：AEM至Adobe Campaign example-aem-to-adobe-campaign

AEM與Campaign之間的標準整合是以JSON和JSSP (JavaScript伺服器頁面)為基礎。這些JSSP檔案可在Campaign主控台中找到，且全部以 aec (Adobe Experience Cloud)開頭。

NOTE

如需此範例，請參閱[封裝共用]中的Geometrixx。

在此範例中，已建立新的自訂JSSP檔案，並從AEM端呼叫該檔案來擷取結果。例如，它可用來從Adobe Campaign擷取資料，或將資料儲存至Adobe Campaign。

若要在Adobe Campaign中建立JSSP檔案，請按一下新增圖示。
輸入此JSSP檔案的名稱。在此範例中，使用了 cus：custom.jssp （表示它位於 cus 名稱空間）。

將下列程式碼放入jssp-file中：

code language-none
`<% var origin = request.getParameter("origin"); document.write("Hello from Adobe Campaign, origin : " + origin); %>`

儲存您的工作。其餘的工作在AEM中。

在AEM端建立簡單的servlet，以便呼叫此JSSP。在此範例中，您可以假設以下情況：

您的連線在AEM和Campaign之間正常運作
已在 /content/geometrixx-outdoors 上設定Campaign雲端服務

此範例中最重要的物件是 GenericCampaignConnector，其可讓您在Adobe Campaign端呼叫（取得和發佈） jssp檔案。

以下是一個小的程式碼片段：

code language-none

code language-none
`@Reference private GenericCampaignConnector campaignConnector; ... Map<String, String> params = new HashMap<String, String>(); params.put("origin", "AEM"); CallResults results = campaignConnector.callGeneric("/jssp/cus/custom.jssp", params, credentials); return results.bodyAsString();`

@Reference
private GenericCampaignConnector campaignConnector;
...
Map<String, String> params = new HashMap<String, String>();
params.put("origin", "AEM");
CallResults results = campaignConnector.callGeneric("/jssp/cus/custom.jssp", params, credentials);
return results.bodyAsString();

在此範例中，您必須將憑證傳遞至呼叫。您可以透過getCredentials()方法取得，您可在其中傳入已設定Campaign雲端服務的頁面。

code language-xml

code language-xml
`// page containing the cloudservice for Adobe Campaign Configuration config = campaignConnector.getWebserviceConfig(page.getContentResource().getParent()); CampaignCredentials credentials = campaignConnector.retrieveCredentials(config);`

// page containing the cloudservice for Adobe Campaign
Configuration config = campaignConnector.getWebserviceConfig(page.getContentResource().getParent());
CampaignCredentials credentials = campaignConnector.retrieveCredentials(config);

完整的程式碼如下：

import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.ServletException;

import org.apache.felix.scr.annotations.Reference;
import org.apache.felix.scr.annotations.sling.SlingServlet;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingSafeMethodsServlet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.day.cq.mcm.campaign.CallResults;
import com.day.cq.mcm.campaign.CampaignCredentials;
import com.day.cq.mcm.campaign.GenericCampaignConnector;
import com.day.cq.wcm.api.Page;
import com.day.cq.wcm.api.PageManager;
import com.day.cq.wcm.api.PageManagerFactory;
import com.day.cq.wcm.webservicesupport.Configuration;

@SlingServlet(paths="/bin/campaign", methods="GET")
public class CustomServlet extends SlingSafeMethodsServlet {

 private final Logger log = LoggerFactory.getLogger(this.getClass());

 @Reference
 private GenericCampaignConnector campaignConnector;

 @Reference
 private PageManagerFactory pageManagerFactory;

 @Override
 protected void doGet(SlingHttpServletRequest request,
   SlingHttpServletResponse response) throws ServletException,
   IOException {

  PageManager pm = pageManagerFactory.getPageManager(request.getResourceResolver());

  Page page = pm.getPage("/content/geometrixx-outdoors");

  String result = null;
  if ( page != null) {
   result = callCustomFunction(page);
  }
  if ( result != null ) {
   PrintWriter pw = response.getWriter();
   pw.print(result);
  }
 }

 private String callCustomFunction(Page page ) {
  try {
   Configuration config = campaignConnector.getWebserviceConfig(page.getContentResource().getParent());
   CampaignCredentials credentials = campaignConnector.retrieveCredentials(config);

   Map<String, String> params = new HashMap<String, String>();
   params.put("origin", "AEM");
   CallResults results = campaignConnector.callGeneric("/jssp/cus/custom.jssp", params, credentials);
   return results.bodyAsString();
  } catch (Exception e ) {
   log.error("Something went wrong during the connection", e);
  }
  return null;

 }

}

範例2：從Adobe Campaign到AEM example-adobe-campaign-to-aem

AEM提供立即可用的API，可擷取Siteadmin Explorer檢視中任何位置可用的物件。

chlimage_1-17

NOTE

如需此範例，請參閱[封裝共用]中的Geometrixx。

對於總管中的每個節點，都有一個API連結至該節點。例如，對於節點：

http://localhost:4502/siteadmin#/content/campaigns/geometrixx/scott-recommends

API是：

http://localhost:4502/content/campaigns/geometrixx/scott-recommends.1.json

URL .1.json 的結尾可以根據您想要取得的子層級數目由 .2.json、.3.json 取代。若要取得所有關鍵字，可使用無限：

http://localhost:4502/content/campaigns/geometrixx/scott-recommends.infinity.json

為了使用API，AEM預設會使用基本驗證。

名為 amcIntegration.js 的JS程式庫可在6.1.1 （build 8624及更新版本）中使用，該程式庫會在其他數個程式庫中實作該邏輯。

AEM API呼叫 aem-api-call

loadLibrary("nms:amcIntegration.js");

var cmsAccountId = sqlGetInt("select iExtAccountId from NmsExtAccount where sName=$(sz)","aemInstance")
var cmsAccount = nms.extAccount.load(String(cmsAccountId));
var cmsServer = cmsAccount.server;

var request = new HttpClientRequest(cmsServer+"/content/campaigns/geometrixx.infinity.json")
aemAddBasicAuthentication(cmsAccount, request);
request.method = "GET"
request.header["Content-Type"] = "application/json; charset=UTF-8";
request.execute();
var response = request.response;
