将JsonArray添加到JsonObject

标签: java json arrays

我今天搜索了很多关于这个主题的内容。但我找不到它,如何将JSONArray添加到JSONObject?

因为每次我这样做都会收到此错误:Stackoverflow

        JSONObject fillBadkamerFormaatFromContentlet(Structure structure, String formaat) {
    JSONObject jsonObject = new JSONObject();
    JSONArray arr = new JSONArray();

    BadkamerFormaat badkamerFormaat = new BadkamerFormaat();
    BadkamerTegel badkamerTegel;
    List<Contentlet> contentlets = getContentletsByStructure(structure);
    badkamerFormaat.formaat = formaat;
    badkamerFormaat.tegels = new ArrayList<BadkamerTegel>();

    try {
        jsonObject.put("formaat", formaat); 
    } catch (JSONException e1) {
        throw new RuntimeException(e1);
    }

    for(Contentlet contentlet : contentlets) {
        badkamerTegel = new BadkamerTegel();
        badkamerTegel.naam = contentlet.getStringProperty(ParameterNames.toolBetegelVeldNaam);
        try {
            badkamerTegel.afbeeldingTegel = contentlet.getBinary(ParameterNames.toolBetegelVeldTegelAfbeelding).getPath();
            badkamerTegel.afbeeldingBadkamer = contentlet.getBinary(ParameterNames.toolBetegelVeldBadkamerAfbeelding).getCanonicalPath();
            arr.put(badkamerTegel.toJSON());
        } catch (IOException e) {
            throw new RuntimeException(e);
        }   
    }

    try {
        jsonObject.put("aoColumnDefs",arr);
    } catch (JSONException e) {
        throw new RuntimeException(e);
    }

    return jsonObject;          
}

我收到此错误:

我想要的JSON:只有最后一个JsonArray出错:

{
           "wand": [
        {
            formaat: 'vierkant15x15'
            tegels: [
                    {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ]
        }
        ,

        {
            formaat: 'vierkant17x15'
            tegels: [
                    {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ]
        }
    ]

,             “vloer”:[             {                 格式:'vierkant10x15'                 tegels:[                         {naam:'',imgThumb:'/ bla / bla.png',largeImg:'/ bla / bla2.png'}                         ,{naam:'',imgThumb:'/ bla / bla.png',largeImg:'/ bla / bla2.png'}                         ]             }             ,

        {
            formaat: 'vierkant45x15'
            tegels: [
                    {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ]
        }
    ]

}

我认为这是你正在使用的API的一个问题(也就是bug)。 JSONArray实现Collection(从此API派生的json.org实现具有JSONArray实现集合)。 JSONObject有一个重载的put()方法,它接收一个Collection并将其包装在JSONArray中(从而导​​致问题)。我认为您需要强制使用其他JSONObject.put()方法:

    jsonObject.put("aoColumnDefs",(Object)arr);

您应该向供应商提交错误,非常确定他们的JSONObject.put(String,Collection)方法已损坏。

这里是简单的代码

List <String> list = new ArrayList <String>();
list.add("a");
list.add("b");
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
        array.put(list.get(i));
}
JSONObject obj = new JSONObject();
try {
    obj.put("result", array);
} catch (JSONException e) {
 // TODO Auto-generated catch block
e.printStackTrace();
}
pw.write(obj.toString());

答案 2 :(得分:3)

您的清单:

List<MyCustomObject> myCustomObjectList;

您的JSONArray:

// Don't need to loop through it. JSONArray constructor do it for you.
new JSONArray(myCustomObjectList)

您的回复:

return new JSONObject().put("yourCustomKey", new JSONArray(myCustomObjectList));

你的帖子/放置http正文请求将是这样的:

    {
        "yourCustomKey: [
           {
               "myCustomObjectProperty": 1
           },
           {
               "myCustomObjectProperty": 2
           }
        ]
    }

我自己开始了解这一点,对于Android开发非常新,我发现这个视频非常有用。

https://www.youtube.com/watch?v=qcotbMLjlA4

它专门用于在视频中于19:30将JSONArray发送到JSONObject。

JSONArray视频到JSONObject的代码:

JSONArray queryArray = quoteJSONObject.names();

ArrayList<String> list = new ArrayList<String>();

for(int i = 0; i < queryArray.length(); i++){
    list.add(queryArray.getString(i));
}

for(String item : list){
    Log.v("JSON ARRAY ITEMS ", item);
}

只需尝试以下简单的解决方案:

JsonObject body=new JsonObject();
body.add("orders", (JsonElement) orders);

只要我的JSON请求如下:

{
      "role": "RT",
      "orders": [
        {
          "order_id": "ORDER201908aPq9Gs",
          "cart_id": 164444,
          "affiliate_id": 0,
          "orm_order_status": 9,
          "status_comments": "IC DUE - Auto moved to Instruction Call Due after 48hrs",
          "status_date": "2020-04-15",
        }
      ]
    }
