Question

我想创建jsonarray，但我是新来的，所以尽我所能，但无法做到这一点，任何人都可以帮助我。谢谢我已经知道我从这个数组获取数据，但现在我想以这种格式的json数组插入我的文本以发布到数据库

{
  "ServiceVisitID": 1,
  "ServiceItemID": 2,
  "ItemDescription": "sample string 3",
  "SerialNumber": "sample string 4",
  "ItemLocation": "sample string 5",
  "ServiceTasks": [
    {
      "TaskID": 1,
      "Task": "sample string 2",
      "Description": "sample string 3",
      "done": true,
      "Notes": "sample string 5",
      "ReasonID": 6,
      "ResultTypeID": 7
    },
    {
      "TaskID": 1,
      "Task": "sample string 2",
      "Description": "sample string 3",
      "done": true,
      "Notes": "sample string 5",
      "ReasonID": 6,
      "ResultTypeID": 7
    }
  ],
  "ItemAttended": true,
  "NotAttendedReasonCode": "sample string 7",
  "ActionRequiredID": 8,
  "ItemsRequired": [
    {
      "ItemID": 1,
      "StockCode": "sample string 2",
      "Description": "sample string 3",
      "Quantity": 4
    },
    {
      "ItemID": 1,
      "StockCode": "sample string 2",
      "Description": "sample string 3",
      "Quantity": 4
    }
  ],
  "FurtherVisitRequired": true,
  "Notes": "sample string 10",
  "ServiceComplete": true,
  "Code":
  "Message": 
}

我现在的代码，我只能制作5个第一个obj，但之后还有更多的ServiceTasks数组，所以我对此感到困惑

 JSONArray jsonArray=new JSONArray();
                                    JSONObject ob=new JSONObject();

                                   ob.put("ServiceVisitID","1");
                                    ob.put("ServiceItemID","1");
                                    ob.put("ItemDescription","check");
                                    ob.put("SerialNumber","check");
                                    JSONObject itemlocationob=  ob.put("SerialNumber");
                                   ob.put("ItemLocation","check");

                                    JSONArray ServiceTasks=new JSONArray();
                                    JSONObject ServiceTasksob=new JSONObject();

                                    ServiceTasksob.put("TaskID","1");
                                    ServiceTasksob.put("TaskID","1");
                                    ServiceTasksob.put("TaskID","1");
                                    ServiceTasks.put(jsonObject1);
                                    ob.put("",ServiceTasks);

Answer 1

JSONObject jObj = new JSONObject();
jObj.put(KEY,VALUE);
JSONArray jArray = new JsonArray();
jArray.put(jObj);
JSONObject mainJson = new JSONObject();
mainJson.put(KEY,mainJson);

Answer 2

    In an JSONObject we can follow as key value pairs
Considering your code,
JSONArray jsonArray=new JSONArray();
                                    JSONObject ob=new JSONObject();

                                   ob.put("ServiceVisitID","1");
                                    ob.put("ServiceItemID","1");
                                    ob.put("ItemDescription","check");
                                    ob.put("SerialNumber","check");
                                    **//  Wrong version
                                    JSONObject itemlocationob=  ob.put("SerialNumber");  
                                    ob.put("ItemLocation","check");**
                                    //
                                    **//Right version
                                    JSONObject itemlocationob=  new JSONObject();
                                    itemlocationob.put("SerialNumber","<some value>");
                                   ob.put("ItemLocation",itemlocationob);

                                    JSONArray ServiceTasks=new JSONArray();
                                    JSONObject ServiceTasksob=new JSONObject();

                                    ServiceTasks.put("TaskID","1");
                                    ServiceTasks.put("TaskID","2");
                                    ServiceTasks.put("TaskID","3");
                                                                                          ServiceTasksob.put("ServiceTasks",ServiceTasks);
                                    ob.put("service",ServiceTasksob);
                                   //**

我想这是你想要建立的json。希望有所帮助!!!
