Android - JSON Array 및 JSON 객체 생성
Android에서 다음 형식으로 JSON을 만들려면 어떻게 해야 합니까?전달되는 API는 JsonArray를 해석하기 때문에 오브젝트는 해석됩니다.아니면 json 오브젝트만 넘겨도 될까요?서비스 콜당 1개의 트랜잭션만 넣으면 되기 때문입니다.
{
"student": [
{
"id": 1,
"name": "John Doe",
"year": "1st",
"curriculum": "Arts",
"birthday": 3/3/1995
},
{
"id": 2,
"name": "Michael West",
"year": "2nd",
"curriculum": "Economic",
"birthday": 4/4/1994
}
]
}
제가 아는 건 JSONObject 뿐입니다.이것처럼 말이다.
JSONObject obj = new JSONObject();
try {
obj.put("id", "3");
obj.put("name", "NAME OF STUDENT");
obj.put("year", "3rd");
obj.put("curriculum", "Arts");
obj.put("birthday", "5/5/1993");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
어떤 아이디어라도.감사해요.
다음 코드를 사용합니다.
JSONObject student1 = new JSONObject();
try {
student1.put("id", "3");
student1.put("name", "NAME OF STUDENT");
student1.put("year", "3rd");
student1.put("curriculum", "Arts");
student1.put("birthday", "5/5/1993");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONObject student2 = new JSONObject();
try {
student2.put("id", "2");
student2.put("name", "NAME OF STUDENT2");
student2.put("year", "4rd");
student2.put("curriculum", "scicence");
student2.put("birthday", "5/5/1993");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray jsonArray = new JSONArray();
jsonArray.put(student1);
jsonArray.put(student2);
JSONObject studentsObj = new JSONObject();
studentsObj.put("Students", jsonArray);
String jsonStr = studentsObj.toString();
System.out.println("jsonString: "+jsonStr);
public JSONObject makJsonObject(int id[], String name[], String year[],
String curriculum[], String birthday[], int numberof_students)
throws JSONException {
JSONObject obj = null;
JSONArray jsonArray = new JSONArray();
for (int i = 0; i < numberof_students; i++) {
obj = new JSONObject();
try {
obj.put("id", id[i]);
obj.put("name", name[i]);
obj.put("year", year[i]);
obj.put("curriculum", curriculum[i]);
obj.put("birthday", birthday[i]);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
jsonArray.put(obj);
}
JSONObject finalobject = new JSONObject();
finalobject.put("student", jsonArray);
return finalobject;
}
JSONObject obj = new JSONObject();
try {
obj.put("id", "3");
obj.put("name", "NAME OF STUDENT");
obj.put("year", "3rd");
obj.put("curriculum", "Arts");
obj.put("birthday", "5/5/1993");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray js=new JSONArray(obj.toString());
JSONObject obj2 = new JSONObject();
obj2.put("student", js.toString());
메서드를 생성하여 매개 변수를 전달하고 json을 응답으로 가져올 수 있습니다.
private JSONObject jsonResult(String Name,int id, String curriculum) throws JSONException {
JSONObject json = null;
json = new JSONObject("{\"" + "Name" + "\":" + "\"" + Name+ "\""
+ "," + "\"" + "Id" + "\":" + id + "," + "\"" + "Curriculum"
+ "\":" + "\"" + curriculum+ "\"" + "}");
return json;
}

다음 코드와 같이 동적으로 작성할 수 있습니다.
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("username", userName);
jsonBody.put("email", email);
jsonBody.put("phone", contactNumber);
jsonBody.put("password", password);
jsonBody.put("carType", carType);
jsonBody.put("fcmToken", "lljlkdsajfljasldfj;lsa");
jsonBody.put("profilePhoto", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg");
JSONObject document = new JSONObject();
try {
document.put("DL", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("Registration", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("Insurance", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("CarInside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("CarOutside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
} catch (JSONException e) {
e.printStackTrace();
}
jsonBody.put("documents", document.toString());
Log.i("MAHDI", "Hello: Mahdi: Data: " + jsonBody);
} catch (JSONException e) {
e.printStackTrace();
}
또한 createDocument 메서드 코드:
public JSONArray createDocument(String id, String imageUrl) {
JSONObject dlObject = new JSONObject();
try {
dlObject.put("_id", id);
dlObject.put("uriPath", imageUrl);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray dlArray = new JSONArray();
dlArray.put(dlObject);
return dlArray;
}
다음은 트라이캐치가 필요 없는 간단한 버전(단, 짧지 않은 버전)입니다.
Map<String, String> data = new HashMap<>();
data.put("user", "mark@facebook.com");
data.put("pass", "123");
JSONObject jsonData = new JSONObject(data);
필드에 jsonObject를 추가하려면 다음과 같이 하십시오.
data.put("socialMedia", (new JSONObject()).put("facebookId", "1174989895893400"));
data.put("socialMedia", (new JSONObject()).put("googleId", "106585039098745627377"));
아쉽게도 put() 메서드 때문에 트라이캐치가 필요합니다.
다시 시도 캐치를 피하고 싶은 경우(권장하지 않지만 올바른 형식의 json 문자열을 보장할 수 있다면 문제 없음) 다음과 같이 하십시오.
data.put("socialMedia", "{ 'facebookId': '1174989895893400' }");
JsonArrays 등에 대해서도 같은 작업을 수행할 수 있습니다.
건배.
답을 찾을 때까지 고군분투하고 있었어
GSON 라이브러리 사용:
Gson gson = Gson(); String str_json = gson.tojson(jsonArray);`json 어레이를 전달합니다.이것은 자동 문자열화 됩니다.이 옵션은 나에게 완벽하게 작동했다.
JSONObject jsonResult = new JSONObject();
try {
jsonResult.put("clave", "valor");
jsonResult.put("username", "iesous");
jsonResult.put("password", "1234");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.d("DEV","jsonResult->"+jsonResult);
Map<String, String> params = new HashMap<String, String>();
//** Temp array
List<String[]> tmpArray = new ArrayList<>();
tmpArray.add(new String[]{"b001","book1"});
tmpArray.add(new String[]{"b002","book2"});
//** Json Array Example
JSONArray jrrM = new JSONArray();
for(int i=0; i<tmpArray.size(); i++){
JSONArray jrr = new JSONArray();
jrr.put(tmpArray.get(i)[0]);
jrr.put(tmpArray.get(i)[1]);
jrrM.put(jrr);
}
//Json Object Example
JSONObject jsonObj = new JSONObject();
try {
jsonObj.put("plno","000000001");
jsonObj.put("rows", jrrM);
}catch (JSONException ex){
ex.printStackTrace();
}
// Bundles them
params.put("user", "guest");
params.put("tb", "book_store");
params.put("action","save");
params.put("data", jsonObj.toString());
// Now you can send them to the server.
public void DataSendReg(String picPath, final String ed2, String ed4, int bty1, String bdatee, String ed1, String cno, String address , String select_item, String select_item1, String height, String weight) {
final ProgressDialog dialog=new ProgressDialog(SignInAct.this);
dialog.setMessage("Process....");
AsyncHttpClient httpClient=new AsyncHttpClient();
RequestParams params=new RequestParams();
File pic = new File(picPath);
try {
params.put("image",pic);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
params.put("height",height);
params.put("weight",weight);

params.put("pass",ed4);
params.put("bid",bty1);
params.put("birthdate",bdatee);
params.put("city","Surat");
params.put("state","Gujarat");
httpClient.post(WebAPI.REGAPI,params,new JsonHttpResponseHandler(){
@Override
public void onStart() {
dialog.show();
}
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
try {
String done=response.get("msg").toString();
if(done.equals("s")) {
Toast.makeText(SignInAct.this, "Registration Success Fully", Toast.LENGTH_SHORT).show();
DataPrefrenceMaster.SetRing(ed2);
startActivity(new Intent(SignInAct.this, LoginAct.class));
finish();
}
else if(done.equals("ex")) {
Toast.makeText(SignInAct.this, "email already exist", Toast.LENGTH_SHORT).show();
}else Toast.makeText(SignInAct.this, "Registration failed", Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
Toast.makeText(SignInAct.this, "e :: ="+e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
Toast.makeText(SignInAct.this, "Server not Responce", Toast.LENGTH_SHORT).show();
Log.d("jkl","error");
}
@Override
public void onFinish() {
dialog.dismiss();
}
});
}
JSONObject를 사용해야 합니다.풋 방식
