Question

{
    "data": 
    {
        "map":
        {
            "allowNestedValues": true,
            "create": "2012-12-11 15:16:13",
            "title": "test201212110004",
            "transitions": []
        }
    },
    "msg": "success",
    "code": "0"
}

以上是JsonObject，data是JsonObject。

如您所知，如何将其转换为String "msg":"success"，我不能直接在data的值之外添加双引号。

Answer 1

@hsz我们有内置的方法将JsonObject转换为String。你为什么不用它。

JSONObject json = new JSONObject();
json.toString();

Answer 2

你可以使用

JsonObject.getString("msg");

Answer 3

您可以使用：

JSONObject jsonObject = new JSONObject();
jsonObject.toString();

如果您想获得特定值，可以使用：

jsonObject.getString("msg");

或整数值

jsonObject.getInt("codeNum");

Answer 4

在括号外添加双引号，并将{}中的双引号替换为\"

所以："{\"data\":{..... }"

Answer 5

您可以尝试Gson转换器，以获得json.stringify之类的exacy转换

val jsonString:String = jsonObject.toString()
val gson:Gson = GsonBuilder().setPrettyPrinting().create()
val json:JsonElement = gson.fromJson(jsonString,JsonElement.class)
val jsonInString:String= gson.toJson(json)
println(jsonInString)

Answer 6

JSONObject metadata = (JSONObject) data.get("map"); //for example
String jsonString = metadata.**toJSONString()**;

Answer 7

     This should get all the values from the above JsonObject  
     System.out.println(jsonObj.get("msg"));
     System.out.println(jsonObj.get("code"));

     JsonObject obj= jsonObj.get("data").getAsJsonObject().get("map").getAsJsonObject();
     System.out.println(obj.get("allowNestedValues"));
     System.out.println(obj.get("create"));
     System.out.println(obj.get("title"));
     System.out.println(obj.get("transitions"));

Answer 8

您可以使用可靠的库GSON

private static final Type DATA_TYPE_JSON = 
        new TypeToken<JSONObject>() {}.getType();           
JSONObject orderJSON = new JSONObject();
orderJSON.put("noOfLayers", "2");
orderJSON.put("baseMaterial", "mat");
System.out.println("JSON == "+orderJSON.toString());
String dataAsJson = new Gson().toJson(orderJSON, DATA_TYPE_JSON);
System.out.println("Value of dataAsJson == "+dataAsJson.toString());
String data = new Gson().toJson(dataAsJson);
System.out.println("Value of jsonString == "+data.toString());

Answer 9

 var data= {"data": {"map":{"allowNestedValues": true,"create": "2012-12-11 15:16:13","title": "test201212110004","transitions": []}},"msg": "success","code": "0"}

O / P：

Object {data: Object, msg: "success", code: "0"}

使用JSON.stringify将整个数据转换为字符串，如下所示

var stringData = JSON.stringify(data);

O / P：

"{"data":{"map":{"allowNestedValues":true,"create":"2012-12-11 15:16:13","title":"test201212110004","transitions":[]}},"msg":"success","code":"0"}"

使用JSON.parse将整个字符串对象转换为JSON对象，如下所示

var orgdata = JSON.parse(stringData);

O / P：

Object {data: Object, msg: "success", code: "0"}

Answer 10

我认为你需要这个：

假设你有这样的样本JSON：

{"ParamOne":"InnerParamOne":"InnerParamOneValue","InnerParamTwo":"InnerParamTwoValue","InnerParamThree":"InnerParamThreeValue","InnerParamFour":"InnerParamFourValue","InnerParamFive":"InnerParamFiveValue"}}

转换为字符串：

String response = {\"ParamOne\":{\"InnerParamOne\":\"InnerParamOneValue\",\"InnerParamTwo\":\"InnerParamTwoValue\",\"InnerParamThree\":\"InnerParamThreeValue\",\"InnerParamFour\":\"InnerParamFourValue\",\"InnerParamFive\":\"InnerParamFiveValue\"}} ;

只需更换＆＃34;通过\＆＃34;
