这是这个问题的延续
以下是原始代码的缩写版本。我尝试包含最相关的部分，并省略了 cron 作业使用的脚本部分，该作业使用值更新数据存储区。
然后，在sendFollowUp()处理程序中，第二个 cron 作业在数据存储中查询这些值，然后使用推送任务队列将这些值作为参数发送，这些参数最终在 REST API 调用中使用到另一个发送人员（实体）的服务数据存储区中的电子邮件。
我不知道如何在不通过表单提交发布请求的情况下在同一个处理程序中使用发布请求来跟进获取请求。这需要在 sendFollowUp 处理程序中发生。我发现的大多数示例都包括提交表单。但是，我不想那样做。我只是希望它自动与 cron 作业和任务队列一起工作。
