我是 Java 和放心 API 的新手。我的要求是，我必须更新收到的 json 响应，并再次调用相同的 API，并将更新的响应作为该 api 的输入内容

Response response = Seller.postSeller(environmentURI, someinput);
               String responseString = response.asString();

        JSONObject responseObject = new JSONObject(responseString);
                JSONArray dataArray = responseObject.getJSONObject("data");

        for (int i = 0; i < dataArray.length(); i++) {
            JSONObject jsonObject = dataArray.getJSONObject(i);

                       responseObject.put("currentDate", SystemDate.getTodaysDate());
                       }


                       //Again I have to call this API

                       Response response = Seller.postSeller(environmentURI, someinput); 
                       //Here I have update "currentDate": "2019-02-23" to todays date and have to pass that as someinput string

收到回复：

{ data:[ 
                   {"Id": "1",
                   "Number": "G24101457",
                    "oldDate": "2016-01-01",
                    "currentDate": "2019-02-23"
                    },
                    {"Id": "2",
                   "Number": "G24101457",
                    "oldDate": "2016-01-01",
                    "currentDate": "2019-02-23"
                    }
                    ]
                    }

基本上我的要求是更新 json 并作为正文传递给 post 请求

五元素

您错误地更改了中的currentDate字段responseObject。您必须jsonObject在 for 循环内进行修改。

jsonObject.put("currentDate", new Date());

获取数据数组有一个小错误，应该是：

JSONArray dataArray = responseObject.getJSONArray("data");

使用相同的调用 API responseObject：

Response response = Seller.postSeller(environmentURI, responseObject.toString());

注意：我在currentdate字段中输入的日期new Date()只是一个示例，您可以将日期输入所需的格式。

这是运行示例：

import org.json.JSONArray;
import org.json.JSONObject;

import java.time.LocalDate;
import java.util.Date;

public class ModifyResponse {
    public static void main(String[] args) {
        //Response response = Seller.postSeller(environmentURI, someinput);
        //String responseString = response.asString();
        String responseString = "{ 'data': [{ 'Id': '1', 'Number': 'G24101457', 'oldDate': '2016-01-01', 'currentDate': '2019-02-23' }, { 'Id': '2', 'Number': 'G24101457', 'oldDate': '2016-01-01', 'currentDate': '2019-02-23' } ] }";
        JSONObject responseObject = new JSONObject(responseString);
        JSONArray dataArray = responseObject.getJSONArray("data");

        for (int i = 0; i < dataArray.length(); i++) {
            JSONObject jsonObject = dataArray.getJSONObject(i);
            //Here I have update "currentDate": "2019-02-23" to todays date and have to pass that as someinput string
            jsonObject.put("currentDate", new Date());
        }

        System.out.println("Modified data: " + responseObject);
        //Again I have to call this API
        //Response response = Seller.postSeller(environmentURI, responseObject.toString());
    }
}
