我是邮递员的新手，我想知道如何从JSON文件声明请求正文，而JSON文件是我使用集合运行器多次迭代传递请求正文中的值/数据的同一个文件。

如果有人可以帮助我提出这个主张，将不胜感激...

在此处输入代码

我的JSON输入文件：

[
    {
      "POLCODE":"APOL279906","EnrolmentSegmentvalue":"ADF","startDate":"2019-12-01",}
]

请求正文：

[
{
    "code": "{{POLCODE}}","brandCode": " ","lineOfBusinessCode": "HEALTH_INSURANCE","enrolmentSegment": [
        {
            "value": "{{EnrolmentSegmentvalue}}","startDate": "{{startDate}}","endDate": ""
        }
    ]
  }   
]   

响应正文：

{
"saleDate": "2019-12-01","calculateonCancellation": false,"code": "APOL279906","rebateApplicant": [{
    "startDate": "2019-12-01","declarationDate": "2019-12-01"
}],"enrolmentSegment": [{
    "flexCodeDefinitionCode": "ENROLMENT_SEGMENTS","startDate": "2019-12-01","value": "ADF"
}]

}
