我正在使用 json 解析器對象解析 json 文件。我無法訪問請求結構及其內部正文內容。我編寫了如下代碼：private static final String filePath = "D:\\score_api.json";public static void main(String[] args) throws FileNotFoundException, IOException, ParseException { FileReader reader = new FileReader(filePath); JSONParser jsonParser = new JSONParser(); JSONObject jsonObject = (JSONObject) jsonParser.parse(reader); System.out.println("++++++++++++++++++\n"+jsonObject); // prints the whole json content. success! JSONObject structure = (JSONObject) jsonObject.get("provider"); System.out.println("provider name: " + structure.get("name")); // prints the provider name. success! JSONArray req= (JSONArray) jsonObject.get("interactions"); Iterator i = req.iterator(); while (i.hasNext()) { JSONObject reqObj = (JSONObject) i.next(); System.out.println("description: " + reqObj.get("description") +"\n"); System.out.println("request body: " + reqObj.get("request")); // prints full request body System.out.println("path: " + reqObj.get("path") +"\n"); // Failing, getting null value. System.out.println("reponse body: " + reqObj.get("response") +"\n"); // Success } }它的輸出：++++++++++++++++++++ {"full json file content prints"}提供者名稱：SIS 描述：API POST Score 請求正文：{"full request body prints"} 路徑：null響應正文：{“狀態(tài)”：200}我正在努力訪問請求正文內容。及其子部分。我想訪問 'path' 的值和其他內部值，如 'adptPolVal'、'eEcoId' 和 Source 結構。我是java的新手，我嘗試但失敗了。任何幫助將不勝感激！提前致謝 ！這是我的json文件內容...{ "consumer": { "name": "Consumer1" }, "provider": { "name": "provider_a" }, "interactions": [ { "description": "API Score", "providerStates": [ { "name": "", "params": {} } ],

您可以使用以下類作為參考來獲得您想要的值。
請確保根據(jù)您的輸出正確使用 getJSONArray() 和 getJSONObject() 方法。
package com.test.test;
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.codehaus.jettison.json.JSONArray;
import org.codehaus.jettison.json.JSONException;
import org.codehaus.jettison.json.JSONObject;
public class Test {
public static void main(String[] args) throws IOException, JSONException {
String filePath = "C://Users//hello//Desktop//New Text Document.txt";
String string = FileUtils.readFileToString(new File(filePath));
JSONObject jsonObject = new JSONObject(string);
JSONArray jsonArray = jsonObject.getJSONArray("interactions");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject reqObj = jsonArray.getJSONObject(i);
System.out.println("description: " + reqObj.get("description") +"\n");
System.out.println("request body: " + reqObj.get("request")); // prints full request body
System.out.println("reponse body: " + reqObj.get("response") +"\n"); // Success
JSONObject requestBoday = reqObj.getJSONObject("request");
JSONObject body = requestBoday.getJSONObject("body");
}
}
}

嘗試替換此行
JSONArray req= (JSONArray) jsonObject.get("interactions");和 ：
JSONArray req= (JSONArray)jsonObject.getJSONArray("interactions");添加回答
