Convert JsonObject to String

问题:

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

Above is a JsonObject, the data is a JsonObject.

How to convert it to a String like "msg":"success" as you know, i can't directly add a double quotes outside data's value.

回答1:

@hsz we have inbuild method to convert jsonObject to string. Why don't you use that.

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

回答2:

you can use

JsonObject.getString("msg");  

回答3:

Add a double quotes outside the brackets and replace double quotes inside the {} with \"

So: "{\"data\":{..... }"

回答4:

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

回答5:

     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")); 

回答6:

You can use reliable library GSON

private static final Type DATA_TYPE_JSON =          new TypeToken() {}.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()); 

回答7:

 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"} 

Use JSON.stringify to convert entire data into string like below

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"}" 

Use JSON.parse to convert entire string object into JSON Object like below

var orgdata = JSON.parse(stringData); 

o/p:

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

回答8:

I think you need this :

Suppose you have Sample JSON like this :

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

Converted to String :

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

Just replace " by \"
