在適用性表單提交上建立促銷活動設定檔

本文將說明在Adobe Campaign Standard中針對適用性表單提交建立設定檔所需的步驟。 此程式可運用自訂提交機制來處理最適化表單提交作業。

本教學課程將逐步說明在適用性表單提交上建立Campaign設定檔的步驟。 若要完成此使用案例,我們必須執行下列作業

  • 建立AEM Service(CampaignService)以使用REST API建立Adobe Campaign Standard設定檔
  • 建立自訂提交動作以處理最適化表單提交
  • 叫用CampaignService的createProfile方法

建立AEM服務

建立AEM服務以建立Adobe Campaign設定檔。 此AEM服務會從OSGI設定中擷取Adobe Campaign憑證。 取得促銷活動認證後,即會產生存取權杖,並使用存取權杖HTTP Post呼叫,在Adobe Campaign中建立設定檔。 以下是建立設定檔的程式碼。

自訂提交

建立自訂提交處理常式,以處理最適化表單提交。 在此自訂提交處理常式中,我們將呼叫CampaignService的createProfile方法。 createProfile方法接受表示需要建立的配置檔案的JSONObject。

若要進一步了解AEM Forms中的自訂提交處理常式,請依照此link操作

以下是自訂提交中的程式碼

aemforms.campaign.core.CampaignService addNewProfile = sling.getService(aemforms.campaign.core.CampaignService.class);
com.google.gson.JsonObject profile = new com.google.gson.JsonObject();
profile.addProperty("email",request.getParameter("email"));
profile.addProperty("firstName",request.getParameter("fname"));
profile.addProperty("lastName",request.getParameter("lname"));
profile.addProperty("mobilePhone",request.getParameter("phone"));

String pkey = addNewProfile.createProfile(profile);

測試解決方案

定義服務和自訂提交動作後,即可測試我們的解決方案。 要測試解決方案,請執行以下步驟
