Mule 基于输入日期创建日期数组,mule,dataweave,mule4,Mule,Dataweave,Mule4,我有一个JSON负载，如下所示： { "start_date": "20210314", "end_date": "20210613" } 我希望以这样的方式获取数组，它包含： [ { "start_date": "20210314", "end_date": "20210404" }, {

我有一个JSON负载，如下所示：

{
    "start_date": "20210314",
    "end_date": "20210613"
}

我希望以这样的方式获取数组，它包含：

[
  {
    "start_date": "20210314",
    "end_date": "20210404"
  },
  {
     "start_date": "20210405",
     "end_date": "20210426"
  },
  {
     "start_date": "20210427",
     "end_date": "20210518"
  }.... till the end date in JSON payload
]

开始日期和结束日期已以日期格式强制执行。每个对象的日期间隔为21天 我正在mule 4中创建一个REST API，使用和数学运算符应该可以得到所需的结果

输入

{
    "start_date": "20210314",
    "end_date": "20210824"
}
