通常，在实施项目时，您在AEM和Adobe Campaign中都拥有自定义代码。使用现有API，您可以在Adobe Campaign中从AEM或从AEM到Adobe Campaign调用自定义代码。本文档介绍如何执行此操作。

先决条件 prerequisites

您必须安装以下软件：

Adobe Experience Manager
Adobe Campaign 6.1

有关详细信息，请参阅将AEM与Adobe Campaign 6.1集成。

示例1：从AEM到Adobe Campaign example-aem-to-adobe-campaign

AEM和Campaign之间的标准集成基于JSON和JSSP (JavaScript Server Page)。这些JSSP文件可在Campaign控制台中找到，且全部以 aec (Adobe Experience Cloud)开头。

NOTE

对于此示例，请参阅“包共享”中提供的Geometrixx。

在此示例中，创建了新的自定义JSSP文件，并从AEM端调用该文件以检索结果。例如，它可用于从Adobe Campaign中检索数据，或将数据保存到Adobe Campaign中。

在Adobe Campaign中，要创建JSSP文件，请单击新建图标。
输入此JSSP文件的名称。在此示例中，使用了 cus：custom.jssp（这意味着它位于 cus 命名空间中）。

将以下代码置于jssp-file中：

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

保存您所做的工作。其余的工作在AEM中。

在AEM端创建一个简单的servlet，以便调用此JSSP。在此示例中，您可以假设以下情况：

您在AEM和Campaign之间建立了连接
已在 /content/geometrixx-outdoors 上配置Campaign云服务

此示例中最重要的对象是 GenericCampaignConnector，它允许您在Adobe Campaign端调用（获取和发布）jssp文件。

以下是一个小的代码片段：

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();

在此示例中，必须将凭据传递到调用。您可以通过getCredentials()方法获取它们，其中您传入的页面配置了Campaign云服务。

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);

完整的代码如下所示：

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.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;

 }

}

示例2：从Adobe Campaign到AEM example-adobe-campaign-to-aem

AEM提供现成的API，用于检索可在siteadmin资源管理器视图中任何位置使用的对象。

chlimage_1-17

NOTE

对于此示例，请参阅“包共享”中提供的Geometrixx。

对于资源管理器中的每个节点，都有一个API链接到该节点。例如，对于节点：

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

API是：

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

URL .1.json 的末尾可以替换为 .2.json、.3.json（根据您感兴趣的子级别数）。若要获取所有关键字，可以使用 infinity：

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

为使用API，AEM默认使用基本身份验证。

名为 amcIntegration.js 的JS库在6.1.1（内部版本8624及更高版本）中可用，该库在其他多个库中实现该逻辑。

AEM API调用 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;
