使用ACS配置文件预填自适应表单

在本部分中,我们将使用从ACS获取的用户档案信息预填自适应表单。 AEM Forms具有预填自适应表单的强大功能。

要了解有关预填自适应表单的更多信息,请阅读本教程

要通过从ACS获取数据来预填充自适应表单,我们假定ACS中存在与已登录AEM用户具有相同电子邮件的用户档案。 例如,如果登录AEM的人员的电子邮件ID是csimms@adobe.com,则我们希望在ACS中找到电子邮件为csimms@adobe.com的用户档案。

需要执行以下步骤,以使用REST API从ACS获取配置文件信息

  • 生成JWT
  • 用于访问令牌的Exchange JWT
  • 对ACS进行REST调用,并通过电子邮件获取配置文件
  • 使用配置文件信息构建XML文档
  • 返回将由AEM Forms使用的XML文档的InputStream

将预填充服务与自适应表单关联

以下是用于从ACS获取和返回用户档案信息的代码。

在第68行中,我们获取AEM用户的电子邮件ID。 通过对Adobe Campaign Standard进行REST调用,可获取用户档案详细信息。 从获取的配置文件详细信息中,以AEM Forms所理解的方式构建XML文档。 将返回此文档的输入流以供AEM Forms使用。
