从字符串数组创建Json Array

Question

我正在尝试实现以下json对象：

sid将是所有json对象的标题，如下所示：

   {
  "sid": {
    "1662809241632798": {
      "JSON": [
        {
          "path": "root/AuthenticationUnixTime",
          "val1": "1521560221877",
          "val2": "null",
          "comp": "false"
        },
        {
          "path": "root/ClientDate",
          "val1": "1521560221877",
          "val2": "1519818708657",
          "comp": "false"
        },
        {
          "path": "root/ContentSize",
          "val1": "18064",
          "val2": "18029",
          "comp": "false"
        }
      ],
      "XML": [
        {
          "path": "root / recording / procIp",
          "val1": "172.22.6.26",
          "val2": "null",
          "comp": "false"
        },
        {
          "path": "root / recording / procIp",
          "val1": "172.22.6.26",
          "val2": "null",
          "comp": "false"
        },
        {
          "path": "root / recording / messagesSize",
          "val1": "13529",
          "val2": "11982",
          "comp": "false"
        }
      ]
    }
  }
}

为了达到上述目的，我尝试使用此代码：

public void newMethod(){

       JSONArray jsonArray = new JSONArray();
       json=removeNullFromArrayString(json);
       JSONObject mainObj = new JSONObject();
       mainObj.put("SID",sid);
       try{
           for(int i=0;i<json.length;i++){
               JSONObject list = new JSONObject();
               list.put("JSON",json[i]);

               jsonArray.add(list);
           }

            System.out.println(jsonArray.toString());


       }catch (JSONException e1) {
           // TODO Auto-generated catch block
           e1.printStackTrace();
       }


   }

其中“ json”是字符串数组，“ XML”是将添加到json的另一个项目。

我的代码产生的是：

[
  {
    "JSON": "[path: root / AuthenticationUnixTime, val1: 1521560221877, val2: null, comp: false]"
  },

在这个问题上的任何帮助将不胜感激。

Answer 1

问题之一是，如果您还想打印sid，则应该打印mainObj （而不是jsonArray ）。 也是toString方法的调用，即：

System.out.println(mainObj.toString());

是多余的。 toString方法在打印期间自动调用，不需要显式调用：

System.out.println(mainObj);

Answer 2

我已使用示例字符串以所需的相同格式创建JSONObject ..希望对您有所帮助

String jsonString = "[path: root / ClientDate, val1: 1521560221877,val2:1519818708657, comp: false],[path: root / ClientDate, val1: 1521560221877,val2:1519818708657, comp: false]";
    JSONObject mainObj = new JSONObject();
    JSONObject child = new JSONObject();
    JSONObject list;
    JSONObject objectId;

    try {
        String[] json1 = jsonString.split("(?=(,\\[))(,\\[)");
        for (String string : json1) {
            string = string.replaceAll("[\\[\\]]", "");
            String[] json = string.split(",");
            list = new JSONObject();
            for (int i = 0; i < json.length; i++) {
                String[] object = json[i].split(":");
                list.put(object[0], object[1]);
            }

            child.append("JSON", list);

        }
        objectId = new JSONObject();
        objectId.put("123456798", child);
        mainObj.put("SID", objectId);
        System.out.println(mainObj);
    } catch (JSONException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

打印输出

{“ SID”：{“ 123456798”：{“ JSON”：[{“ path”：“ root / ClientDate”，“ val2”：“ 1519818708657”，“ val1”：“ 1521560221877”，“ comp”：“ false” }，{“ path”：“ root / ClientDate”，“ val2”：“ 1519818708657”，“ val1”：“ 1521560221877”，“ comp”：“ false”}]}}}
