JSON으로서의 OkHttp Post Body

JSON으로서의 OkHttp Post Body

그래서 Koush's Ion을 사용했을 때 간단한 방법으로 json body를 게시물에 추가할 수 있었습니다..setJsonObjectBody(json).asJsonObject()

저는 OkHttp로 옮기는데, 그렇게 하는 게 좋은 방법이 아닌 것 같아요.여기저기서 오류 400이 나오네요.

생각나는 사람?

json 문자열로 수동 포맷도 해봤습니다.

String reason = menuItem.getTitle().toString();
JsonObject json = new JsonObject();
json.addProperty("Reason", reason);

String url = mBaseUrl + "/" + id + "/report";

Request request = new Request.Builder()
        .header("X-Client-Type", "Android")
        .url(url)
        .post(RequestBody
                .create(MediaType
                    .parse("application/json"),
                        "{\"Reason\": \"" + reason + "\"}"
                ))
        .build();

client.newCall(request).enqueue(new com.squareup.okhttp.Callback() {
    @Override
    public void onFailure(Request request, IOException throwable) {
        throwable.printStackTrace();
    }

    @Override
    public void onResponse(Response response) throws IOException {
        if (!response.isSuccessful()) throw new IOException(
                "Unexpected code " + response);
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(context, "Report Received", Toast.LENGTH_SHORT).show();
            }
        });
    }
});

/*Ion.with(getContext(), url)
        .setHeader("X-Client-Type", "Android")
        .setJsonObjectBody(json)
        .asJsonObject()
        .setCallback(new FutureCallback<JsonObject>() {
            @Override
            public void onCompleted(Exception e, JsonObject result) {
                Toast.makeText(context, "Report Received", Toast.LENGTH_SHORT).show();
            }
        });*/

그냥 사용하다JSONObject.toString(); OkHttp의 튜토리얼을 보세요.

public static final MediaType JSON
    = MediaType.parse("application/json; charset=utf-8");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
  RequestBody body = RequestBody.create(json, JSON); // new
  // RequestBody body = RequestBody.create(JSON, json); // old
  Request request = new Request.Builder()
      .url(url)
      .post(body)
      .build();
  Response response = client.newCall(request).execute();
  return response.body().string();
}

직접 만들 수 있습니다.JSONObject그리고나서toString().

백그라운드 스레드로 실행해 주세요.doInBackground에AsyncTask.

OkHttp 버전> 4:

import okhttp3.MediaType.Companion.toMediaType

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

val client = OkHttpClient()
val mediaType = "application/json; charset=utf-8".toMediaType()
val body = jsonObject.toString().toRequestBody(mediaType)
val request: Request = Request.Builder()
            .url("https://YOUR_URL/")
            .post(body)
            .build()

var response: Response? = null
try {
    response = client.newCall(request).execute()
    val resStr = response.body!!.string()
} catch (e: IOException) {
    e.printStackTrace()
}
   

OkHttp 버전 3:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

  OkHttpClient client = new OkHttpClient();
  MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  // put your json here
  RequestBody body = RequestBody.create(JSON, jsonObject.toString());
  Request request = new Request.Builder()
                    .url("https://YOUR_URL/")
                    .post(body)
                    .build();

  Response response = null;
  try {
      response = client.newCall(request).execute();
      String resStr = response.body().string();
  } catch (IOException e) {
      e.printStackTrace();
  }

또 다른 접근법은FormBody.Builder().
콜백의 예를 다음에 나타냅니다.

Callback loginCallback = new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        try {
            Log.i(TAG, "login failed: " + call.execute().code());
        } catch (IOException e1) {
            e1.printStackTrace();
        }
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        // String loginResponseString = response.body().string();
        try {
            JSONObject responseObj = new JSONObject(response.body().string());
            Log.i(TAG, "responseObj: " + responseObj);
        } catch (JSONException e) {
            e.printStackTrace();
        }
        // Log.i(TAG, "loginResponseString: " + loginResponseString);
    }
};

그런 다음 우리 자신의 몸을 만듭니다.

RequestBody formBody = new FormBody.Builder()
        .add("username", userName)
        .add("password", password)
        .add("customCredential", "")
        .add("isPersistent", "true")
        .add("setCookie", "true")
        .build();

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(this)
        .build();
Request request = new Request.Builder()
        .url(loginUrl)
        .post(formBody)
        .build();

마지막으로 서버를 호출합니다.

client.newCall(request).enqueue(loginCallback);

kotlin, okhttp v4.* 그렇게 동작하고 있습니다.

// import the extensions!
import okhttp3.MediaType.Companion.toMediaType
import okhttp3.RequestBody.Companion.toRequestBody

// ...

json : String = "..."

val JSON : MediaType = "application/json; charset=utf-8".toMediaType()
val jsonBody: RequestBody = json.toRequestBody(JSON)

// go on with Request.Builder() etc
