应我的请求，我得到以下答复，

{
    "studyDTO": {
        "studyId": 191,
        "studyCode": "test_ispptest2"
    },
    "sites": [],

            "orderOfDisplay": 30
        },
        {
            "studyId": 191,
            "submitValue": "multi_slice_spiral_ct",
            "displayValue": "Multi-Slice Spiral CT",
            "orderOfDisplay": 50
        },
        {

        },
        {

            "submitValue": "unknown",
            "displayValue": "Unknown",

}

在响应中，我收到的5 modality值可以更多，在JSON类型的下一个请求主体中，我希望添加所有modalities，我如何使用JSR223后处理器来完成此操作，
申请样品：

{
    "studyDTO": {
        "studyId": 191,
        "studyCode": "test_ispptest2"
    },
    "allVisits": true,
    "modalities": [
        {
            "studyId": 191,
            "submitValue": "ct",
            "displayValue": "Conventional CT",
            "orderOfDisplay": 30
        },
        {
            "studyId": 191,
            "submitValue": "multi_slice_spiral_ct",
            "displayValue": "Multi-Slice Spiral CT",
            "orderOfDisplay": 50
        },
        {
            "studyId": 191,
            "submitValue": "dxa",
            "displayValue": "DXA",
            "orderOfDisplay": 60
        },
        {
            "studyId": 191,
            "submitValue": "mri",
            "displayValue": "MRI",
            "orderOfDisplay": 100
        },
        {
            "studyId": 191,
            "submitValue": "unknown",
            "displayValue": "Unknown",
            "orderOfDisplay": 240
        }
    ],
    "includePS": null
}

到目前为止我已经开发了，但是不知道如何形成请求JSON

import groovy.json.JsonSlurper
def jsonString = prev.getResponseDataAsString();
def jsonConvert = new JsonSlurper();
def object = jsonConvert.parseText(jsonString);
def modalityS = object.modalities.size().toString();
def modalitySize = modalityS?.isInteger() ? modalityS.toInteger() : null
for (int i = 0; i < modalitySize ; i++) {
    def modalityOrderOfDisplay = object.modalities[i].orderOfDisplay;
    def modalSubmitValue = object.modalities[i].submitValue;
    def modalDisplayValue = object.modalities[i].displayValue;
    log.info('----------------------->'+modalityOrderOfDisplay);
    log.info('----------------------->'+modalSubmitValue);
    log.info('----------------------->'+modalDisplayValue);
}
