如何在Java中解析JSON结构化JSON数组对象 [英] How to parse JSON structured-JSON Array Object in Java

问题描述

我正在尝试解析此JSON代码

i'm trying to parse this JSON code

{
  "resultCode":"350",
  "message":"OK",
  "result":1,
  "data":
{
    "totalCount":"2",
    "videos":[
      {
        "videoId":"73bfedf534",
        "VideoUrl":"www.videourlexample.com",
        "title":"vbsample1",
        "description":""
      },

{
        "videoId":"73bfedf534",
        "VideoUrl":"www.videourlexample.com",
        "title":"vbsample2",
        "description":""
      }
    ]
  }
}

我只能解析这个.

"resultCode":"350",
"message":"OK",
"result":1,

这是Java代码

JSONObject jsonObject = (JSONObject)  
//return the JSON code above.
jsonParser.parse(getHTML("...httpRequest..."));

    // get a String from the JSON object
    String resultCode = (String) jsonObject.get("resultCode");
    System.out.println("[RESULTCODE] The message is: " + resultCode);


    // get a String from the JSON object
    String message = (String) jsonObject.get("message");
    System.out.println("[MESSAGE] The message is: " + message);

    // get a number from the JSON object
    long result =  (long) jsonObject.get("result");
    System.out.println("[RESULT] The resultCode is: " + result);

我无法解析数据".有人可以帮我吗? 我想分别从json数组中获取每个值...例如resultCode，消息和结果.

I can't parse the "data". Someone can help me? I would like to take each value from the json array separately... like resultCode, message and result.

谢谢.

推荐答案

 JSONObject mainObj= new JSONObject(yourJSON);
 String resultCode= mainObj.get("resultCode");
 String message= mainObj.get("message");
 String result= mainObj.get("result");
 JSONObject dataObj = mainObj.get("data");
 JSONArray jsonArray = (JSONArray) dataObj.get("videos");
 for (int i = 0; i <jsonArray.length(); i++) {
   JSONObject obj= jsonArray.get(i);
   String videoId=obj.get("videoId");
   String videoUrl=obj.get("VideoUrl");
   String title=obj.get("title");
   String description=obj.get("description");
    System.out.println("videoId="+videoId   +"videoUrl="+videoUrl+"title=title"+"description="+description);        
}
 System.out.println("resultCode"+resultCode+"message"+message+"result"+result);
