我有一个请求有效负载（JSON格式），它有一个包含1000个对象的数组，每个对象有6个键值对，其中5个键值对是我使用参数化从csv文件中阅读的，第6个键值必须是数组中每个对象未来日期的唯一日期值。
我尝试了这个与时移功能，为1迭代工作，但我想执行它的n-迭代次数。
我为此检查了Groovy代码，但我对Groovy一无所知，我已经开始学习它了。
如何在JMeter中实现这一点？
此外，在从HTTP请求默认值-参数或测试计划-用户定义变量阅读时移函数时，它不会读取每个对象的不同日期，而是复制每个对象中第一个变量的相同日期。

{
  “deviceNumber": “XX”,
  “array: [
    {
      “keyValue1: “${value1_ReadFromCSV}”,
      "keyValue2”: “${value2_ReadFromCSV}”,
      "keyValue3”: “${value3_ReadFromCSV}”,
      "keyValue4”: “${value4_ReadFromCSV}”,
      "keyValue5”: “${value5_ReadFromCSV}”,
      "keyValue6”: "2020-05-23” (Should be dynamically generated)
    },
    {
      “keyValue7: “value7_ReadFromCSV”,
      "keyValue8”: "value8_ReadFromCSV",
      "keyValue9”: "value9_ReadFromCSV",
      "keyValue10”: "value10_ReadFromCSV",
      "keyValue11”: "value11_ReadFromCSV",
      "keyValue12”: "2020-05-24” (Should be dynamically generated)
    },
    .
    .
    .
    .
    {
      “keyValue995: “value995_ReadFromCSV”,
      "keyValue996”: "value996_ReadFromCSV",
      "keyValue997”: "value997_ReadFromCSV",
      "keyValue998”: "value998_ReadFromCSV",
      "keyValue999”: "value999_ReadFromCSV",
      "keyValue1000”: "2025–12-31” (Should be dynamically generated)
    }
  ]
}

通过逐行阅读csv文件并使用groovy将每一行存储到一个变量中，我已经得到了部分解决方案。但是，我不想直接将行存储到变量中，而是从csv文件的每一行创建一个JSON对象，为数组中的每个对象创建一个唯一的未来日期。
csv文件为：（注：我已经删除了csv中的日期列，因为我不再需要它。

deviceNumber,keyValue1,keyValue2,keyValue3,keyValue4,keyValue5,keyValue7,keyValue8,keyValue9,keyValue10,keyValue11,keyValue12,keyValue13,keyValue15,keyValue15,keyValue16

请提出任何参考/例子来做到这一点。
